This week rbowes added an LPE exploit for Zimbra with Postfix. The exploit leverages a vulnerability whereby the Zimbra user can run postfix as root which in turn is capable of executing arbitrary shellscripts. This can be abused for reliable privilege escalation from the context of the zimbra
service account to root
. As of this time, this vulnerability remains unpatched.
rbowes also added an RCE for Zimbra as well. This exploit can be used to remotely obtain the initial access necessary to exploit CVE-2022-3569 and escalate privileges to root. This exploit leverages a path traversal vulnerability to write a malicious JSP file to the web directory which yields code execution. The vulnerability does not require authentication however it should be noted that pax must not be present on the target in order for it to be exploitable. A Zimbra patch adds pax as a requirement, so either the patch must not have been applied or pax must have been explicitly removed.
Community member heyder submitted an exploit for multiple Fortinet products this week. The exploit involves an authentication bypass that is leveraged to establish an SSH session with the target. Unfortunately, the tested FortiGate v7.2.1 instance used during testing indicated that the target could not be used for SSH port forwarding.
Metasploit is capable of importing scan data produced by a variety of tools such as Qualys and Nessus. This week jmartin switched the XML parser used while processing Qualys scan files to obtain a dramatic performance improvement. Scans data which previously took hours to import takes only a few minutes now.

and you can get more details on the changes since the last blog post from
GitHub:
If you are a git
user, you can clone the Metasploit Framework repo (master branch) for the latest.
To install fresh without using git, you can use the open-source-only Nightly Installers or the
binary installers (which also include the commercial edition).
