Release of PoC Exploit for New Drupal Flaw Once Again Puts Sites Under Attack
April 26, 2018Swati Khandelwal
Only a few hours after the Drupal team releases latest updates to fix a new remote code execution flaw in its content management system software, hackers have already started exploiting the vulnerability in the wild. Announced yesterday, the newly discovered vulnerability ( CVE-2018-7602 ) affects Drupal 7 and 8 core and allows remote attackers to achieve exactly same what previously discovered Drupalgeddon2 (CVE-2018-7600) flaw allowed—complete take over of affected websites. Although Drupal team has not released any technical details of the vulnerability to prevent immediate exploitation, two individual hackers have revealed some details, along with a proof-of-concept exploit just a few hours after the patch release. If you have been actively reading every latest story on The Hacker News, you must be aware of how the release of Drupalgeddon2 PoC exploit derived much attention, which eventually allowed attackers actively hijack websites and spread cryptocurrency miners , b

April 14, 2018Swati Khandelwal
Hackers have started exploiting a recently disclosed critical vulnerability in Drupal shortly after the public release of working exploit code. Two weeks ago, Drupal security team discovered a highly critical remote code execution vulnerability, dubbed Drupalgeddon2 , in its content management system software that could allow attackers to completely take over vulnerable websites. To address this vulnerability the company immediately released updated versions of Drupal CMS without releasing any technical details of the vulnerability, giving more than a million sites enough time to patch the issue. Two days ago, security researchers at Check Point and Dofinity published complete technical details about this vulnerability (CVE-2018-7600), using which, a Russian security researcher published a proof-of-concept (PoC) exploit code for Drupalgeddon2 on GitHub. The Drupalgeddon2 vulnerability that affects all versions of Drupal from 6 to 8 allows an unauthenticated, remote attack

Apache Tomcat Patches Important Remote Code Execution Flaw

Apache Tomcat Patches Important Remote Code Execution Flaw
October 05, 2017Swati Khandelwal
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

7-Year-Old Samba Flaw Lets Hackers Access Thousands of Linux PCs Remotely
May 25, 2017Swati Khandelwal
A 7-year-old critical remote code execution vulnerability has been discovered in Samba networking software that could allow a remote attacker to take control of an affected Linux and Unix machines. Samba is open-source software (re-implementation of SMB networking protocol) that runs on the majority of operating systems available today, including Windows, Linux, UNIX, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to share network shared folders, files, and printers with Windows operating system. The newly discovered remote code execution vulnerability ( CVE-2017-7494 ) affects all versions newer than Samba 3.5.0 that was released on March 1, 2010. "All versions of Samba from 3.5.0 onwards are vulnerable to a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it," Samba wrote in an advisory published Wed

Internet-Connected Medical Washer-Disinfector Found Vulnerable to Hacking
March 27, 2017Swati Khandelwal
Internet-of-Things devices are turning every industry into the computer industry, making customers think that their lives would be much easier with smart devices. There are, of course, some really good reasons to connect certain devices to the Internet. For example, remotely switching on your A/C a few minutes before you enter your home, instead of leaving it blasting all day. But does everything need to be connected? Of course, not. One such example is the latest bug report at Full Disclosure, affecting an Internet-connected washer-disinfector appliance by Germany-based manufacturer Miele . The Miele Professional PG 8528 appliance, which is used in medical establishments to clean and properly disinfect laboratory and surgical instruments, is suffering from a Web Server Directory Traversal vulnerability. Jens Regel of German consultancy Schneider & Wulf has discovered the flaw ( CVE-2017-7240 ) that allows an unauthenticated, remote attacker to access directories oth

WikiLeaks Won't Disclose CIA Exploits To Companies Until Certain Demands Are Met

WikiLeaks Won't Disclose CIA Exploits To Companies Until Certain Demands Are Met
March 18, 2017Swati Khandelwal
It's been over a week since Wikileaks promised to hand over more information on hacking tools and tactics of the Central Intelligence Agency (CIA) to the affected tech companies, following a leak of a roughly 8,761 documents that Wikileaks claimed belonged to CIA hacking units. "We have decided to work with them, to give them some exclusive access to some of the technical details we have, so that fixes can be pushed out," WikiLeaks' founder Julian Assange said during a Facebook Live press conference last week. However, it looks like the things aren't that easier for tech companies as they look. After days of waiting, Assange made its first contact with Apple, Microsoft, and Google this week and finally made his intentions clear – no sharing of bugs and vulnerabilities the CIA is or was allegedly taking advantage of until certain demands are met. Multiple anonymous sources familiar with the matter told Motherboard that Assange sent an email to Apple,

A Simple JavaScript Exploit Bypasses ASLR Protection On 22 CPU Architectures

A Simple JavaScript Exploit Bypasses ASLR Protection On 22 CPU Architectures
February 16, 2017Swati Khandelwal
Security researchers have discovered a chip flaw that could nullify hacking protections for millions of devices regardless of their operating system or application running on them, and the worse — the flaw can not be entirely fixed with any mere software update. The vulnerability resides in the way the memory management unit (MMU), a component of many CPUs, works and leads to bypass the Address Space Layout Randomization (ASLR) protection. ASLR is a crucial security defense deployed by all modern operating systems from Windows and Linux to macOS, Android, and the BSDs. In general, ASLR is a memory protection mechanism which randomizes the location where programs run in a device's memory. This, in turn, makes it difficult for attackers to execute malicious payloads in specific spots in memory when exploiting buffer overflows or similar bugs. In short, for attackers, it's like an attempt to burglarize a house blindfolded. But now a group of researchers, known as VUSe

Check If Your Netgear Router is also Vulnerable to this Password Bypass Flaw
January 31, 2017Swati Khandelwal
Again bad news for consumers with Netgear routers: Netgear routers hit by another serious security vulnerability, but this time more than two dozens router models are affected. Security researchers from Trustwave are warning of a new authentication vulnerability in at least 31 models of Netgear models that potentially affects over one million Netgear customers. The new vulnerability, discovered by Trustwave's SpiderLabs researcher Simon Kenin, can allow remote hackers to obtain the admin password for the Netgear router through a flaw in the password recovery process. Kenin discovered the flaw ( CVE-2017-5521 ) when he was trying to access the management page of his Netgear router but had forgotten its password. Exploiting the Bug to Take Full Access on Affected Routers So, the researcher started looking for ways to hack his own router and found a couple of exploits from 2014 that he leveraged to discover this flaw which allowed him to query routers and retrieve thei

Update — Hacker Claims to Have Hacked the FBI, But It Wasn't
January 05, 2017Mohit Kumar
Update: A hacker yesterday claimed to have hacked the FBI's website running on Plone CMS, but it seems it wasn't hacked using any zero-day vulnerability in Plone. We contacted Plone security team and updated this story (see below) with official statements. A hacker, using Twitter handle CyberZeist , has claimed to have hacked the FBI's website (fbi.gov) and leaked personal account information of several FBI agents publically. CyberZeist had initially exposed the flaw on 22 December, giving the FBI time to patch the vulnerability in its website's code before making the data public. The hacker exploited a zero-day vulnerability in the Plone CMS , an Open Source Content Management software used by FBI to host its website, and leaked personal data of 155 FBI officials to Pastebin , including their names, passwords, and email accounts. CyberZeist tweeted multiple screenshots as proof of his claims, showing his unauthorized access to server and database files usi

Ubuntu’s Crash Report Tool Allows Remote Code Execution

Ubuntu’s Crash Report Tool Allows Remote Code Execution
December 16, 2016Swati Khandelwal
No software is immune to being Hacked! Not even Linux. A security researcher has discovered a critical vulnerability in Ubuntu Linux operating system that would allow an attacker to remotely compromise a target computer using a malicious file. The vulnerability affects all default Ubuntu Linux installations versions 12.10 (Quantal) and later. Researcher Donncha O'Cearbhaill discovered the security bug which actually resides in the Apport crash reporting tool on Ubuntu. A successful exploit of this CrashDB code injection issue could allow an attacker to remotely execute arbitrary code on victim's machine. All an attacker needs is to trick the Ubuntu user into opening a maliciously booby-trapped crash file. This would inject malicious code in Ubuntu OS's crash file handler, which when parsed, executes arbitrary Python code. "The code first checks if the CrashDB field starts with { indicating the start of a Python dictionary," O'Cearbhaill explain

North Korea's Linux-based Red Star OS can be Hacked Remotely with just a Link

North Korea's Linux-based Red Star OS can be Hacked Remotely with just a Link
December 06, 2016Wang Wei
North Korea's own homegrown computer operating system, that's supposed to be fully hacker proof and more secure than foreign OS, like Microsoft's Windows, can easily be hacked remotely. A group of hackers managed to break into Red Star OS — North Korea's government sanctioned Linux-based OS — using just a link. Red Star OS is North Korea's own homegrown OS that looks remarkably just like Apple's OS X and gives North Korean authorities more control over the computers, providing not only security but also spying tools that help track files in a way that if the government wants, every bit of user's data can be traced easily. According to the information security company Hacker House , Red Star OS contains a critical vulnerability that makes it possible for hackers to gain remote access to any PC running North Korea's OS just by tricking victims into opening a hyperlink. The latest version of Red Star OS ships with a Firefox-based web browser cal

Firefox Zero-Day Exploit to Unmask Tor Users Released Online
November 30, 2016Swati Khandelwal
Hackers are actively exploiting a zero-day vulnerability in Firefox to unmask Tor Browser users, similar to what the FBI exploited during an investigation of a child pornography site. Tor (The Onion Router) is an anonymity software that not only provides a safe heaven to human rights activists, journalists, government officials, but also is a place where drugs, assassins for hire, child pornography, and other illegal activities has allegedly been traded. A Javascript zero-day exploit currently being actively exploited in the wild is designed to remotely execute malicious code on the Windows operating system via memory corruption flaw in Firefox web browser. The exploit code was publicly published by an admin of the SIGAINT privacy-oriented public email service on the Tor-Talk mailing list. The mailing list message reveals that the zero-day exploit affecting Firefox is currently being exploited against Tor Browser users by unknown attackers to leak the potentially identifyi

NTP DoS Exploit Released — Update Your Servers to Patch 10 Flaws
November 23, 2016Mohit Kumar
A proof-of-concept (PoC) exploit for a critical vulnerability in the Network Time Protocol daemon (ntpd) has been publically released that could allow anyone to crash a server with just a single maliciously crafted packet. The vulnerability has been patched by the Network Time Foundation with the release of NTP 4.2.8p9, which includes a total of 40 security patches, bug fixes, and improvements. The NTP daemon is used in almost every device that needs to synchronize time on computer clocks. NTP got the most attention in late 2014 and 2015 when hackers used it to launch highly amplified DDoS attacks against services. The flaw which affects NTP.org's nptd versions prior to 4.2.8p9, but not including ntp-4.3.94, has been discovered by security researcher Magnus Stubman, who privately disclosed it to the Network Time Foundation on June 24. A patch for the vulnerability was developed and sent to Stubman on 29th September and just two days later, the researcher acknowledged t

Cisco Exploit Leaked in NSA Hack Modifies to Target Latest Version of Firewalls
August 24, 2016Mohit Kumar
Recently released NSA exploit from " The Shadow Brokers " leak that affects older versions of Cisco System firewalls can work against newer models as well. Dubbed ExtraBacon , the exploit was restricted to versions 8.4.(4) and earlier versions of Cisco's Adaptive Security Appliance (ASA) – a line of firewalls designed to protect corporate, government networks and data centers. However, the exploit has now been expanded to 9.2.(4) after researchers from Hungary-based security consultancy SilentSignal were able to modify the code of ExtraBacon to make it work on a much newer version of Cisco's ASA software. Both Cisco and Fortinet have confirmed their firewalls are affected by exploits listed in the Shadow Brokers cache that contained a set of " cyber weapons " stolen from the Equation Group . The Equation Group is an elite hacking group tied to the NSA's offensive Tailored Access Operations (TAO) and linked to the previous infamous Regin and S

If you are a torrent lover and have registered on  BitTorrent community forum website, then you may have had your personal details compromised, along with your hashed passwords. The BitTorrent team has announced that its community forums have been hacked, which exposed private information of hundreds of thousands of its users. As of now, BitTorrent is the most visited torrent client around the world with more than 150 Million monthly active users. Besides this, BitTorrent also has a dedicated community forum that has over hundreds of thousands of registered members with tens of thousands of daily visitors. A recent security alert by the team says the forum database has been compromised by hackers who were able to get their hands on its users’ passwords, warning its users to update their passwords as soon as possible. The vulnerability is believed to be originated at one of its vendors, who alerted the BitTorrent team about the issue earlier this week. "The vulnera

FBI paid Hacker $1.3 Million to Unlock San Bernardino Shooter's iPhone

FBI paid Hacker $1.3 Million to Unlock San Bernardino Shooter's iPhone
April 22, 2016Swati Khandelwal
In Brief Guess how much the FBI has paid an unknown grey-hat hacker to break into San Bernardino Shooter's iPhone? FBI Director James Comey hinted during an interview that the FBI spent more than $1.3 Million for breaking into the iPhone of a suspected terrorist and found nothing useful on it. Apple's  legal battle with the Federal Bureau of Investigation (FBI) ended following the bureau's announcement last month that it bought a hacking tool to break into the locked iPhone 5C belonging to the alleged San Bernardino shooter Syed Farook. At the time, the FBI did not disclose the name of the third party neither it revealed the cost of the hacking tool. But yesterday while speaking at the Aspen Security Forum in London, FBI Director James Comey gave a hint on the price it gave to the unnamed "outside party" for the hacking solution after Apple refused to help the agency bypass the iPhone's security mechanisms. The FBI Paid Over $1.3 MILLION f

July 30, 2015Wang Wei
Bad week for Android. Just days after a critical Stagefright vulnerability was revealed in the widely popular mobile platform, another new vulnerability threatens to make most Android devices unresponsive and practically unusable to essential tasks. Security researchers at Trend Micro have developed an attack technique that could ultimately crash more than 55 percent of Android phones , almost making them completely unresponsive and useless to perform very basic functions, including to make or receive calls. The dangerous security flaw affects any device running Android 4.3 Jelly Bean and later, including the latest Android 5.1.1 Lollipop , potentially putting hundreds of millions of Android users vulnerable to hackers. The flaw surfaced two days after Zimperium researchers warned that nearly 950 Million Android phones can be hijacked by sending a simple text message. Dubbed Stagefright , the vulnerability is more serious because it required no end-user interaction at
