Hey Webmasters, are you using Memcached to boost the performance of your website? Beware! It might be vulnerable to remote hackers. Three critical Remote Code Execution vulnerabilities have been reported in Memcached by security researcher Aleksandar Nikolich at Cisco Talos Group that expose major websites, including Facebook, Twitter, YouTube, Reddit, to hackers. Memcached is a fabulous piece of open-source distributed caching system that allows objects to be stored in memory. It has been designed to speed up dynamic web applications by reducing stress on the database that helps administrators to increase performance and scale web applications. Memcached is widely used by thousands upon thousands of websites, including popular social networking sites such as Facebook, Flickr, Twitter, Reddit, YouTube, Github, and many more. Nikolich says that he discovered multiple integer overflow bugs in Memcached that could be exploited to remotely run arbitrary code on the targeted s...

Yahoo! was recently impacted by a critical web application vulnerabilities which left website's database and server vulnerable to hackers. A cyber security expert and penetration tester, Ebrahim Hegazy a.k.a Zigoo from Egypt , has found a serious SQL injection vulnerability in Yahoo's website that allows an attacker to remotely execute any commands on its server with Root Privileges. According to Hegazy blog post , the SQLi vulnerability resides in a domain of Yahoo! website i.e. https://innovationjockeys.net/tictac_chk_req.php . Any remote user can manipulate the input to the " f_id " parameter in the above URL, which could be exploited to extract database from the server. While pentesting, he found username and password ( encoded as Base64 ) of Yahoo!' admin panel stored in the database. He decoded the Administrator Password and successfully Logged in to the Admin panel. Furthermore, SQL injection flaw also facilitate the attacker to exploit Remote Cod...

Microsoft's  Patch Tuesday update  for the month of March has been made officially available with 71 fixes spanning across its software products such as Windows, Office, Exchange, and Defender, among others. Of the total 71 patches, three are rated Critical and 68 are rated Important in severity. While none of the vulnerabilities are listed as actively exploited, three of them are publicly known at the time of release. It's worth pointing out that Microsoft separately  addressed 21 flaws  in the Chromium-based Microsoft Edge browser earlier this month. All the three critical vulnerabilities remediated this month are remote code execution flaws impacting HEVC Video Extensions ( CVE-2022-22006 ), Microsoft Exchange Server ( CVE-2022-23277 ), and VP9 Video Extensions ( CVE-2022-24501 ). The Microsoft Exchange Server vulnerability, which was reported by researcher Markus Wulftange, is also noteworthy for the fact that it requires the attacker to be authenticated to ...

The updates are also in addition to 30 issues addressed by Microsoft in its Chromium-based Edge browser since last month's Patch Tuesday edition and one side-channel flaw impacting certain processor models offered by AMD ( CVE-2023-20569  or  Inception ). ADV230003 concerns an already known security flaw tracked as  CVE-2023-36884 , a remote code execution vulnerability in Office and Windows HTML that has been actively exploited by the Russia-linked RomCom threat actor in attacks targeting Ukraine as...

Microsoft on Tuesday kicked off its first set of updates for 2022 by  plugging 96 security holes  across its software ecosystem, while urging customers to prioritize patching for what it calls a critical "wormable" vulnerability. Of the 96 vulnerabilities, nine are rated Critical and 89 are rated Important in severity, with six zero-day publicly known at the time of the release. This is in addition to  29 issues  patched in Microsoft Edge on January 6, 2022. None of the disclosed bugs are listed as under attack. The patches cover a swath of the computing giant's portfolio, including Microsoft Windows and Windows Components, Exchange Server, Microsoft Office and Office Components, SharePoint Server, .NET Framework, Microsoft Dynamics, Open-Source Software, Windows Hyper-V, Windows Defender, and Windows Remote Desktop Protocol (RDP).

Security researchers have discovered not one or two, but a total of seven security vulnerabilities in the popular open source Dnsmasq network services software, three of which could allow remote code execution on a vulnerable system and hijack it. Dnsmasq is a widely used lightweight network application tool designed to provide DNS (Domain Name System) forwarder, DHCP (Dynamic Host Configuration Protocol) server, router ads and network boot services for small networks. Dnsmasq comes pre-installed on various devices and operating systems, including Linux distributions such as Ubuntu and Debian, home routers, smartphones and Internet of Things (IoT) devices. A shodan scan for "Dnsmasq" reveals around 1.1 million instances worldwide. Recently, Google's security team reviewed Dnsmasq and discovered seven security issues, including DNS-related remote code execution, information disclosure, and denial-of-service (DoS) issues that can be triggered via DNS or DHCP. ...

Facebook has paid out its largest Bug Bounty ever of $33,500 to a Brazilian security researcher for discovering and reporting a critical Remote code execution vulnerability, which potentially allows the full control of a server. In September, ' Reginaldo Silva' found an XML External Entity Expansion vulnerability affecting the part of Drupal that handled OpenID, which allows attacker to read any files on the webserver. As a feature, Facebook allows users to access their accounts using OpenID in which it receives an XML document from 3rd service and parse it to verify that it is indeed the correct provider or not i.e. Receives at https://www.facebook.com/openid/receiver.php  In November 2013, while testing Facebook's ' Forgot your password ' functionality, he found that the OpenID process could be manipulated to execute any command on the Facebook server remotely and also allows to read arbitrary files on the webserver. In a Proof-of-Concept , ...

As much as you protect your electronics from being hacked, hackers are clever enough at finding new ways to get into your devices. But, you would hope that once a flaw discovered it would at least be fixed in few days or weeks, but that's not always the case. A three-year-old security vulnerability within a software component used by more than 6.1 Million smart devices still remains unpatched by many vendors, thereby placing Smart TVs, Routers, Smartphones, and other Internet of Things (IoT) products at risk of exploit. Security researchers at Trend Micro have brought the flaw to light that has been known since 2012 but has not been patched yet. Remote Code Execution Vulnerabilities  Researchers discovered a collection of Remote Code Execution (RCE) vulnerabilities in the Portable SDK for UPnP , or libupnp component – a software library used by mobile devices, routers, smart TVs, and other IoT devices to stream media files over a network. The flaws occur du...

While Windows users are currently in fear of getting their systems hijacked by the WannaCry ransomware outbreak, Apple users are sitting relaxed, thinking that malware attacks are something that happens to Windows users, and not Apple. But you are mistaken – Apple products are also not immune to the hack attacks and malware infections, as an ebook can hack your Mac, iPhone, and iPad. Apple on Monday pushed out software updates for iOS, macOS, Safari, tvOS, iCloud, iTunes, and watchOS to fix a total of 67 unique security vulnerabilities, many of which allows attackers to perform remote code execution on an affected system. iOS is 10.3.2 for iPhone, iPad, and iPod Apple's mobile operating system iOS 10.3.2 for the iPhone, iPad and iPod touch addresses 41 security flaws, 23 of which resides in WebKit, including 17 remote code execution and 5 cross-site scripting (XSS) vulnerabilities. Besides this, iOS 10.3.2 also addresses a pair of flaws in iBooks for iOS (CVE-2017-24...
