New Critical RCE Vulnerability Discovered in Apache Struts 2 - Patch Now

New Critical RCE Vulnerability Discovered in Apache Struts 2 - Patch Now

Dec 12, 2023 Vulnerability / Software Security
Apache has released a security advisory warning of a critical security flaw in the Struts 2 open-source web application framework that could result in remote code execution. Tracked as  CVE-2023-50164 , the vulnerability is  rooted  in a flawed "file upload logic" that could enable unauthorized path traversal and could be exploited under the circumstances to upload a malicious file and achieve execution of arbitrary code. Struts is a Java framework that uses the Model-View-Controller ( MVC ) architecture for building enterprise-oriented web applications. Steven Seeley of Source Incite has been credited with discovering and reporting the flaw, which impacts the following versions of the software - Struts 2.3.37 (EOL) Struts 2.5.0 - Struts 2.5.32, and Struts 6.0.0 - Struts 6.3.0 Patches for the bug are available in versions 2.5.33 and 6.3.0.2 or greater. There are no workarounds that remediate the issue. "All developers are strongly advised to perform this upgr
Google Releases Android Update to Patch Actively Exploited Vulnerability

Google Releases Android Update to Patch Actively Exploited Vulnerability

May 06, 2022
Google has released monthly security patches for Android with fixes for 37 flaws across different components, one of which is a fix for an actively exploited Linux kernel vulnerability that came to light earlier this year. Tracked as  CVE-2021-22600  (CVSS score: 7.8), the vulnerability is ranked "High" for severity and could be exploited by a local user to escalate privileges or deny service. The issue relates to a  double-free vulnerability  residing in the  Packet  network protocol implementation in the Linux kernel that could cause memory corruption, potentially leading to denial-of-service or execution of arbitrary code. Patches were released by different Linux distributions, including  Debian ,  Red Hat ,  SUSE , and  Ubuntu  in December 2021 and January 2022. "There are indications that CVE-2021-22600 may be under limited, targeted exploitation," Google  noted  in its Android Security Bulletin for May 2022. Specifics about the nature of the attacks are

Researchers Disclose Unpatched Vulnerabilities in Microsoft Teams Software

Dec 23, 2021
Microsoft said it won't be fixing or is pushing patches to a later date for three of the four security flaws uncovered in its Teams business communication platform earlier this March. The disclosure comes from Berlin-based cybersecurity firm Positive Security, which  found  that the implementation of the link preview feature was susceptible to a number of issues that could "allow accessing internal Microsoft services, spoofing the link preview, and, for Android users, leaking their IP address, and DoS'ing their Teams app/channels." Of the four vulnerabilities, Microsoft is said to have addressed only one that results in IP address leakage from Android devices, with the tech giant noting that a fix for the denial-of-service (DoS) flaw will be considered in a future version of the product. The issues were responsibly disclosed to the company on March 10, 2021. Chief among the flaws is a server-side request forgery ( SSRF ) vulnerability in the endpoint "/urlp

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo
Microsoft Releases Windows Updates to Patch Actively Exploited Vulnerability

Microsoft Releases Windows Updates to Patch Actively Exploited Vulnerability

Aug 11, 2021
Microsoft on Tuesday rolled out  security updates  to address a total of 44 security issues affecting its software products and services, one of which it says is an actively exploited zero-day in the wild. The update, which is the smallest release since December 2019, squashes seven Critical and 37 Important bugs in Windows, .NET Core & Visual Studio, Azure, Microsoft Graphics Component, Microsoft Office, Microsoft Scripting Engine, Microsoft Windows Codecs Library, Remote Desktop Client, among others. This is in addition to  seven security flaws  it patched in the Microsoft Edge browser on August 5. Chief among the patched issues is  CVE-2021-36948  (CVSS score: 7.8), an elevation of privilege flaw affecting Windows Update Medic Service — a service that enables remediation and protection of Windows Update components — which could be abused to run malicious programs with escalated permissions. Microsoft's Threat Intelligence Center has been credited with reporting the flaw
Microsoft Urges Azure Users to Update PowerShell to Patch RCE Flaw

Microsoft Urges Azure Users to Update PowerShell to Patch RCE Flaw

Jul 05, 2021
Microsoft is urging Azure users to  update  the PowerShell command-line tool as soon as possible to protect against a critical remote code execution vulnerability impacting .NET Core. The issue, tracked as  CVE-2021-26701  (CVSS score: 8.1), affects PowerShell versions 7.0 and 7.1 and have been remediated in versions 7.0.6 and 7.1.3, respectively. Windows PowerShell 5.1 isn't impacted by the flaw. Built on the .NET Common Language Runtime (CLR),  PowerShell  is a cross-platform task automation utility that consists of a command-line shell, a scripting language, and a configuration management framework. "A remote code execution vulnerability exists in .NET 5 and .NET Core due to how text encoding is performed," the company  noted in an advisory  published earlier this April, adding that the problem resides in the " System.Text.Encodings.Web " package, which provides types for encoding and escaping strings for use in JavaScript, HTML, and URLs. System.Text.

Cisco VoIP phone vulnerability allow eavesdropping remotely

Cisco VoIP phone vulnerability allow eavesdropping remotely

Dec 15, 2012
Cui, a fifth year grad student from the Columbia University Intrusion Detection Systems Lab and co-founder of Red Balloon Security, has demonstrated an attack on common Cisco-branded Voice over IP (VoIP) phones that could easily eavesdrop on private conversations remotely. The vulnerability Cui demonstrated was based on work he did over the last year on what he called ' Project Gunman v2 ', where a laser printer firmware update could be compromised to include additional, and potentially malicious, code. The latest vulnerability is based on a lack of input validation at the syscall interface. Cui said, " allows arbitrary modification of kernel memory from userland, as well as arbitrary code execution within the kernel. This, in turn, allows the attacker to become root, gain control over the DSP , buttons, and LEDs on the phone. " While he did not specify the precise vulnerability, Cui said it allowed him to patch the phone's software with arbitrary pieces of code, and that this a
