Microsoft Issues Windows Update to Patch 0-Day Used to Spread Emotet Malware

Microsoft Issues Windows Update to Patch 0-Day Used to Spread Emotet Malware

Dec 15, 2021
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

Second Log4j Vulnerability (CVE-2021-45046) Discovered — New Patch Released

Dec 15, 2021
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.

Update Google Chrome to Patch New Zero-Day Exploit Detected in the Wild

Dec 14, 2021
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

Unpatched Unauthorized File Read Vulnerability Affects Microsoft Windows OS

Nov 30, 2021
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

Oct 08, 2021
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
