Multiple high-severity flaws have been uncovered in the open source OpenLiteSpeed Web Server as well as its enterprise variant that could be weaponized to achieve remote code execution. "By chaining and exploiting the vulnerabilities, adversaries could compromise the web server and gain fully privileged remote code execution," Palo Alto Networks Unit 42  said  in a Thursday report. OpenLiteSpeed , the open source edition of LiteSpeed Web Server, is the sixth most popular web server, accounting for 1.9 million unique servers across the world. The first of the three flaws is a directory traversal flaw ( CVE-2022-0072 , CVSS score: 5.8), which could be exploited to access forbidden files in the web root directory. The remaining two vulnerabilities ( CVE-2022-0073  and  CVE-2022-0074 , CVSS scores: 8.8) relate to a case of privilege escalation and command injection, respectively, that could be chained to achieve privileged code execution. "A threat actor who man...

A nascent Linux-based botnet named Enemybot has expanded its capabilities to include recently disclosed security vulnerabilities in its arsenal to target web servers, Android devices, and content management systems (CMS). "The malware is rapidly adopting one-day vulnerabilities as part of its exploitation capabilities," AT&T Alien Labs  said  in a technical write-up published last week. "Services such as VMware Workspace ONE, Adobe ColdFusion, WordPress, PHP Scriptcase and more are being targeted as well as IoT and Android devices." First disclosed by  Securonix  in March and later by  Fortinet , Enemybot has been linked to a threat actor tracked as Keksec (aka Kek Security, Necro, and FreakOut), with early attacks targeting routers from Seowon Intech, D-Link, and iRZ. Enemybot, which is capable of carrying out  DDoS attacks , draws its origins from several other botnets like Mirai, Qbot, Zbot, Gafgyt, and LolFMe. An analysis of the latest variant...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Researchers from Qihoo 360's Netlab security team have released details of a new evolving botnet called " Abcbot " that has been observed in the wild with worm-like propagation features to infect Linux systems and launch distributed denial-of-service (DDoS) attacks against targets. While the earliest version of the botnet dates back to July 2021, new variants observed as recently as October 30 have been equipped with additional updates to strike Linux web servers with weak passwords and are susceptible to N-day vulnerabilities, including a custom implementation of DDoS functionality, indicating that the malware is under continuous development. Netlab's findings also build on a report from Trend Micro early last month, which  publicized  attacks targeting Huawei Cloud with cryptocurrency-mining and cryptojacking malware. The intrusions were also notable for the fact that the malicious shell scripts specifically disabled a process designed to monitor and scan the ser...

The Apache Software Foundation on Thursday released additional security updates for its HTTP Server product to remediate what it says is an "incomplete fix" for an  actively exploited  path traversal and remote code execution flaw that it patched earlier this week. CVE-2021-42013 , as the new vulnerability is identified as, builds upon  CVE-2021-41773 , a flaw that impacts Apache web servers running version 2.4.49 and involves a  path normalization  bug that could enable an adversary to access and view arbitrary files stored on a vulnerable server. Although the flaw was addressed by the maintainers in version 2.4.50, a day after the patches were released it became known that the weakness could also be abused to gain remote code execution if the "mod_cgi" module was loaded and the configuration "require all denied" was absent, prompting Apache to issue another round of emergency updates. "It was found that the fix for CVE-2021-41773 in Apache HTT...

Apache has issued patches to address two security vulnerabilities, including a path traversal and file disclosure flaw in its HTTP server that it said is being actively exploited in the wild. "A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the expected document root," the open-source project maintainers  noted  in an advisory published Tuesday. "If files outside of the document root are not protected by 'require all denied' these requests can succeed. Additionally this flaw could leak the source of interpreted files like CGI scripts." The flaw, tracked as  CVE-2021-41773 , affects only Apache HTTP server version 2.4.49. Ash Daulton and cPanel Security Team have been credited with discovering and reporting the issue on September 29, 2021.

A financially-motivated threat actor notorious for its cryptojacking attacks has leveraged a revised version of their malware to target cloud infrastructures using vulnerabilities in web server technologies, according to new research. Deployed by the China-based cybercrime group  Rocke , the Pro-Ocean cryptojacking malware now comes with improved rootkit and worm capabilities, as well as harbors new evasion tactics to sidestep cybersecurity companies' detection methods, Palo Alto Networks' Unit 42 researchers  said  in a Thursday write-up. "Pro-Ocean uses known vulnerabilities to target cloud applications," the researchers detailed. "In our analysis, we found Pro-Ocean targeting Apache ActiveMQ ( CVE-2016-3088 ), Oracle WebLogic ( CVE-2017-10271 ) and Redis (unsecure instances)." "Once installed, the malware kills any process that uses the CPU heavily, so that it's able to use 100% of the CPU and mine Monero efficiently." First documented...

If your web-server runs on Apache, you should immediately install the latest available version of the server application to prevent hackers from taking unauthorized control over it. Apache recently fixed multiple vulnerabilities in its web server software that could have potentially led to the execution of arbitrary code and, in specific scenarios, even could allow attackers to cause a crash and denial of service. The flaws, tracked as CVE-2020-9490, CVE-2020-11984, CVE-2020-11993, were uncovered by Felix Wilhelm of Google Project Zero, and have since been addressed by the Apache Foundation in the latest version of the software ( 2.4.46 ). The first of the three issues involve a possible remote code execution vulnerability due to a buffer overflow with the "mod_uwsgi" module (CVE-2020-11984), potentially allowing an adversary to view, change, or delete sensitive data depending on the privileges associated with an application running on the server. "[A] Malici...

Russian law enforcement officers have raided the Moscow offices of Nginx—the company behind the world's second most popular web server software—over a copyright infringement complaint filed by Rambler, a Russian Internet portal and email service provider. According to multiple reports from local media and social media, the police conducted searches and has also detained several employees of the company, including Igor Sysoev , the original developer of Nginx and Maxim Konovalov , another co-founder of the company. Over 30% of the websites on the Internet today, including many of the world's most popular sites like Netflix and Twitch, run on the Nginx server. Igor Sysoev created the Nginx web server in the early 2000s and open-sourced it in 2004, after which he founded the company Nginx in 2015 that has now been acquired by F5 Networks , an American technology company, for $ 670 million. According to a copy of the complaint shared on Twitter, Rambler accused that Sys...

Cybersecurity researchers today uncovered details of two new vulnerabilities in the GoAhead web server software, a tiny application widely embedded in hundreds of millions of Internet-connected smart devices. One of the two vulnerabilities, assigned as CVE-2019-5096, is a critical code execution flaw that can be exploited by attackers to execute malicious code on vulnerable devices and take control over them. The first vulnerability resides in the way multi-part/form-data requests are processed within the base GoAhead web server application, affecting GoAhead Web Server versions v5.0.1, v.4.1.1, and v3.6.5. According to the researchers at Cisco Talos, while processing a specially crafted HTTP request, an attacker exploiting the vulnerability can cause use-after-free condition on the server and corrupt heap structures, leading to code execution attacks. The second vulnerability, assigned as CVE-2019-5097, also resides in the same component of the GoAhead Web Server and can be ...

If you use Zoom video conferencing software on your Mac computer—then beware—any website you're visiting in your web browser can turn on your device camera without your permission. Ironically, even if you had ever installed the Zoom client on your device and simply uninstalled it, a remote attacker can still activate your webcam. Zoom is one of the most popular cloud-based meeting platforms that provide video, audio, and screen sharing options to users, allowing them to host webinars, teach online courses, conduct online training, or join virtual meetings online. In a Medium post published today, cybersecurity researcher Jonathan Leitschuh disclosed details of an unpatched critical security vulnerability (CVE-2019-13450) in the Zoom client app for Apple Mac computers, which if combined with a separate flaw, could allow attackers to execute arbitrary code on the targeted systems remotely. Jonathan responsibly reported the security vulnerability to the affected company ov...

One of the most important software companies NGINX , which is also behind the very popular open-source web server of the same name, is being acquired by its rival, F5 Networks , in a deal valued at about $670 million. While NGINX is not a name that you have ever heard of, the reality is that you use NGINX every day when you post a photo, watch streaming video, purchase goods online, or log into your applications at work. NGINX powers over half of the busiest websites in the world. Majority of sites on the Internet today, including The Hacker News, and hundreds of thousands apps, like Instagram, Pinterest, Netflix, and Airbnb are hosted on web servers running NGINX. NGINX web server is the third most widely used servers in the world—behind only Microsoft and Apache, and ahead of Google. In short, the internet as we know it today would not exist without NGINX. F5 Acquires NGINX to Bridge NetOps and DevOps F5 Networks is the industry leader in cloud and security application...

The Apache Software Foundation (ASF) has released security updates to address several vulnerabilities in its Tomcat application server, one of which could allow a remote attacker to obtain sensitive information. Apache Tomcat is an open source web server and servlet system, which uses several Java EE specifications like Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket, and provides a "pure Java" HTTP web server environment for Java concept to run in. Unlike Apache Struts2 vulnerabilities exploited to breach the systems of America credit reporting agency Equifax late last year, new Apache Tomcat vulnerabilities are less likely to be exploited in the wild. Apache Tomcat — Information Disclosure Vulnerability The more critical flaw ( CVE-2018-8037 ) of all in Apache Tomcat is an information disclosure vulnerability caused due to a bug in the tracking of connection closures which can lead to reuse of user sessions in a new connection. The vu...

The Apache Tomcat team has recently patched several security vulnerabilities in Apache Tomcat, one of which could allow an unauthorised attacker to execute malicious code on affected servers remotely. Apache Tomcat, developed by the Apache Software Foundation (ASF), is an open source web server and servlet system, which uses several Java EE specifications like Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket, and provides a "pure Java" HTTP web server environment for Java concept to run in. Unlike Apache Struts2 vulnerabilities , which have recently been exploited to breach the systems of American credit reporting agency Equifax , Apache Tomcat flaws are less likely to be exploited. The critical Remote Code Execution (RCE) vulnerability (CVE-2017-12617) discovered in Apache Tomcat is due to insufficient validation of user-supplied input by the affected software. Only systems with HTTP PUTs enabled (via setting the "read-only" initi...

Etherparty announced Sunday that its ICO (Initial Coin Offering) website selling tokens for a blockchain-based smart contract tool was hacked and the address for sending funds to buy tokens was replaced by a fraudulent address controlled by the hackers. Vancouver-based Etherparty is a smart contract creation tool that allows its users to create smart contracts on the blockchain. Companies like this launch ICO to let them raise funding from multiple sources. Etherparty said the company launched its Fuel token sale on Sunday, October 1 at 9 A.M. PDT, but just 45 minutes, some unknown attackers hacked into its ICO website and replaced the legitimate address by their own, redirecting cryptocurrencies sent by investors into their digital wallet. According to the details released by the Etherparty team, the company detected the hack after just 15 minutes and immediately took its website down for nearly one and half hour to fix the issue, preventing more people from sending funds to ...

Security researchers have discovered a critical remote code execution vulnerability in the popular Apache Struts web application framework, allowing a remote attacker to run malicious code on the affected servers. Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for developing web applications in the Java programming language, which supports REST, AJAX, and JSON. The vulnerability (CVE-2017-9805) is a programming blunder that resides in the way Struts processes data from an untrusted source. Specifically, Struts REST plugin fails to handle XML payloads while deserializing them properly. All versions of Apache Struts since 2008 (Struts 2.1.2 - Struts 2.3.33, Struts 2.5 - Struts 2.5.12) are affected, leaving all web applications using the framework's REST plugin vulnerable to remote attackers. According to one of the security researchers at LGTM, who discovered this flaw, the Struts framework is being used by "an incredibly large number and va...

Sensitive files linked to the United States intelligence agency were reportedly left on a public Amazon server by one of the nation's top intelligence contractor without a password, according to a new report. UpGuard cyber risk analyst Chris Vickery discovered  a cache of 60,000 documents from a US military project for the National Geospatial-Intelligence Agency (NGA) left unsecured on Amazon cloud storage server for anyone to access. The documents included passwords to a US government system containing sensitive information, and the security credentials of a senior employee of Booz Allen Hamilton, one of the country's top defense contractors. Although there wasn't any top secret file in the cache Vickery discovered, the documents included credentials to log into code repositories that could contain classified files and other credentials. Master Credentials to a Highly-Protected Pentagon System were Exposed Roughly 28GB of exposed documents included the privat...

Dark Web is right now going through a very rough time. Just two days ago, a hacker group affiliated with Anonymous broke into the servers of Freedom Hosting II and took down more than 10,000 Tor-based .onion dark websites with an alarming announcement to its visitors, which said: " Hello, Freedom Hosting II, you have been hacked. " Freedom Hosting II is the single largest host of underground websites accessible only through Tor anonymising browser that hosts somewhere between 15 and 20 percent of all sites on the Dark Web, anonymity and privacy researcher Sarah Jamie Lewis estimated . Besides defacing all Dark Web sites hosted on Freedom Hosting II with the same message and stealing its database, the hackers also demanded a ransom for 0.1 Bitcoin (just over $100) to return the compromised data to the hosting service. Now, it has been reported that the stolen database from Freedom Hosting II has publicly been released online to a site hosted on the Tor network, wh...

In last few years, we saw an innumerable rise in ransomware threats ranging from Cryptowall to Locky ransomware discovered last week. Now, another genre of ransomware had been branched out from the family of CTB-Locker Ransomware with an update to infect Websites. The newly transformed ransomware dubbed " CTB-Locker for Websites " exclusively hijacks the websites by locking out its data, which would only be decrypted after making a payment of 0.4 BTC. This seems to be the very first time when any ransomware has actually defaced a website in an attempt to convince its administrator to comply with the ransom demand. However, the infected website admins can unlock any 2 files by the random generator for free as a proof of decryption key works. Here's How CTB-Locker for Websites Ransomware Works Lawrence explained that CTB-Locker ransomware replaces the index page ( the original index.php or index.html ) of the servers hosting websites with the ...

Security researchers from Russian Internet giant Yandex have discovered a new piece of malware that is being used to target Linux and FreeBSD web servers in order to make them a part of the wide botnet, even without the need of any root privileges. Researchers dubbed the malware as Mayhem, a nasty malware modular that includes a number of payloads to cause malicious things and targets to infect only those machines which are not updated with security patches or less likely to run security software. So far, researchers have found over 1,400 Linux and FreeBSD servers around the world that have compromised by the malware , with potentially thousands more to come. Most of the compromised machines are located in the USA, Russia, Germany and Canada. Three security experts, Andrej Kovalev, Konstantin Ostrashkevich and Evgeny Sidorov , who work at Russia-based Internet portal Yandex, discovered the malware targeting *nix servers . They were able to trace transmissions from th...
