Cisco Issues Patch for Critical RCE Vulnerability in RCM for StarOS Software
January 20, 2022Ravie Lakshmanan
Cisco Systems has rolled out fixes for a critical security flaw affecting Redundancy Configuration Manager (RCM) for Cisco StarOS Software that could be weaponized by an unauthenticated, remote attacker to execute arbitrary code and take over vulnerable machines. Tracked as  CVE-2022-20649  (CVSS score: 9.0), the vulnerability stems from the fact that the debug mode has been incorrectly enabled for specific services. "An attacker could exploit this vulnerability by connecting to the device and navigating to the service with debug mode enabled," Cisco said in an advisory. "A successful exploit could allow the attacker to execute arbitrary commands as the root user." The network equipment maker, however, noted that the adversary would need to perform detailed reconnaissance to allow for unauthenticated access to vulnerable devices. Stating that the vulnerability was discovered during internal security testing, Cisco added it found no evidence of active exploitat

" To successfully exploit this vulnerability, an attacker would need valid Advanced User credentials." Unified CCMP and Unified CCDM pro

Meeting Patching-Related Compliance Requirements with TuxCare

Meeting Patching-Related Compliance Requirements with TuxCare
January 13, 2022The Hacker News
Cybersecurity teams have many demands competing for limited resources. Restricted budgets are a problem, and restricted staff resources are also a bottleneck. There is also the need to maintain business continuity at all times. It's a frustrating mix of challenges – with resources behind tasks such as patching rarely sufficient to meet security prerogatives or compliance deadlines. The multitude of different security-related standards have ever stringent deadlines, and it is often the case that business needs don't necessarily align with those requirements. At the core of what TuxCare does is automated live patching – a way to consistently keep critical services safe from security threats, without the need to expend significant resources in doing so, or the need to live with business disruption. In this article, we'll outline how  TuxCare  helps organizations such as yours deal better with security challenges including patching, and the support of end-of-life operating s

Microsoft Issues Windows Update to Patch 0-Day Used to Spread Emotet Malware
December 14, 2021Ravie Lakshmanan
Microsoft has rolled out  Patch Tuesday updates  to address multiple security vulnerabilities in Windows and other software, including one actively exploited flaw that's being abused to deliver Emotet, TrickBot, or Bazaloader malware payloads. The latest monthly release for December fixes a total of 67 flaws, bringing the total number of bugs patched by the company this year to 887, according to the  Zero Day Initiative . Seven of the 67 flaws are rated Critical and 60 are rated as Important in severity, with five of the issues publicly known at the time of release. It's worth noting that this is in addition to the  21 flaws  resolved in the Chromium-based Microsoft Edge browser. The most critical of the lot is  CVE-2021-43890  (CVSS score: 7.1), a Windows AppX installer spoofing vulnerability that Microsoft said could be exploited to achieve arbitrary code execution. The lower severity rating is indicative of the fact that code execution hinges on the logged-on user level,

Second Log4j Vulnerability (CVE-2021-45046) Discovered — New Patch Released
December 14, 2021Ravie Lakshmanan
UPDATE — The severity score of CVE-2021-45046, originally classified as a DoS bug, has since been revised from 3.7 to 9.0, to reflect the fact that an attacker could abuse the vulnerability to send a specially crafted string that leads to "information leak and remote code execution in some environments and local code execution in all environments." The Apache Software Foundation (ASF) has pushed out a new fix for the Log4j logging utility after the previous patch for the recently disclosed  Log4Shell  exploit was deemed as "incomplete in certain non-default configurations." The second vulnerability — tracked as  CVE-2021-45046  — is rated 3.7 out of a maximum of 10 on the CVSS rating system and affects all versions of Log4j from 2.0-beta9 through 2.12.1 and 2.13.0 through 2.15.0, which the project maintainers shipped last week to address a critical remote code execution vulnerability (CVE-2021-44228) that could be abused to infiltrate and take over systems.

December 13, 2021Ravie Lakshmanan
Google has rolled out fixes for five security vulnerabilities in its Chrome web browser, including one which it says is being exploited in the wild, making it the  17th such weakness  to be disclosed since the start of the year. Tracked as  CVE-2021-4102 , the flaw relates to a  use-after-free bug  in the V8 JavaScript and WebAssembly engine, which could have severe consequences ranging from corruption of valid data to the execution of arbitrary code. An anonymous researcher has been credited with discovering and reporting the flaw. As it stands, it's not known how the weakness is being abused in real-world attacks, but the internet giant issued a terse statement that said, "it's aware of reports that an exploit for CVE-2021-4102 exists in the wild." This is done so in an attempt to ensure that a majority of users are updated with a fix and prevent further exploitation by other threat actors. CVE-2021-4102 is the second use-after-free vulnerability in V8 the comp

Unpatched Unauthorized File Read Vulnerability Affects Microsoft Windows OS
November 30, 2021Ravie Lakshmanan
Unofficial patches have been issued to remediate an improperly patched Windows security vulnerability that could allow information disclosure and local privilege escalation (LPE) on vulnerable systems. Tracked as  CVE-2021-24084  (CVSS score: 5.5), the flaw concerns an information disclosure vulnerability in the Windows Mobile Device Management component that could enable an attacker to gain unauthorized file system access and read arbitrary files. Security researcher Abdelhamid Naceri was credited with discovering and reporting the bug in October 2020, prompting Microsoft to address the issue as part of its February 2021 Patch Tuesday updates. But as  observed  by Naceri in June 2021, not only could the patch be bypassed to achieve the same objective, the researcher this month found that the incompletely patched vulnerability could also be  exploited  to gain administrator privileges and run malicious code on Windows 10 machines running the  latest security updates .

New Patch Released for Actively Exploited 0-Day Apache Path Traversal to RCE Attacks
October 07, 2021Ravie Lakshmanan
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
