With names, email addresses, and mobile numbers from underground databases, one person in five is at risk of account compromise even with SMS two-factor authentication in place.

This Metasploit module creates a RAR file that can be emailed to a Zimbra server to exploit CVE-2022-30333. If successful, it plants a JSP-based backdoor in the public web directory, then executes that backdoor. The core vulnerability is a path-traversal issue in unRAR that can extract an arbitrary file to an arbitrary location on a Linux system. This issue is exploitable on Zimbra Collaboration versions 9.0.0 Patch 24 and below and 8.8.15 Patch 31 and below provided that UnRAR versions 6.11 or below are installed.

Ubuntu Security Notice 5550-1 - It was discovered that GnuTLS incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause GnuTLS to crash, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. It was discovered that GnuTLS incorrectly handled the verification of certain pkcs7 signatures. A remote attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code.

do_request in request.c in muhttpd before 1.1.7 allows remote attackers to read arbitrary files by constructing a URL with a single character before a desired path on the filesystem. This occurs because the code skips over the first character when serving files. Arris NVG443, NVG599, NVG589, and NVG510 devices and Arris-derived BGW210 and BGW320 devices are affected.

A month after the algorithms were revealed, some companies have already begun incorporating the future standards into their products and services.

In BIG-IP Versions 16.1.x before 16.1.2.2, 15.1.x before 15.1.6.1, 14.1.x before 14.1.5, and all versions of 13.1.x, when a BIG-IP LTM Client SSL profile is configured on a virtual server to perform client certificate authentication with session tickets enabled, undisclosed requests cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

In BIG-IP Versions 16.1.x before 16.1.3.1 and 15.1.x before 15.1.6.1, when an LTM Client or Server SSL profile with TLS 1.3 enabled is configured on a virtual server, along with an iRule that calls HTTP::respond, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
