Posted Feb 20, 2020
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4289-1 - Jeriko One discovered that Squid incorrectly handled memory when connected to an FTP server. A remote attacker could possibly use this issue to obtain sensitive information from Squid memory. Regis Leroy discovered that Squid incorrectly handled certain HTTP requests. A remote attacker could possibly use this issue to access server resources prohibited by earlier security filters. Guido Vranken discovered that Squid incorrectly handled certain buffer operations when acting as a reverse proxy. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.

Apache James Server 2.3.2 Insecure User Creation / Arbitrary File Write
Posted Feb 20, 2020
Authored by Matthew Aberegg, Michael Burkey, Palaczynski Jakub | Site metasploit.com

This Metasploit module exploits a vulnerability that exists due to a lack of input validation when creating a user. Messages for a given user are stored in a directory partially defined by the username. By creating a user with a directory traversal payload as the username, commands can be written to a given directory. To use this module with the cron exploitation method, run the exploit using the given payload, host, and port. After running the exploit, the payload will be executed within 60 seconds. Due to differences in how cron may run in certain Linux operating systems such as Ubuntu, it may be preferable to set the target to Bash Completion as the cron method may not work. If the target is set to Bash completion, start a listener using the given payload, host, and port before running the exploit. After running the exploit, the payload will be executed when a user logs into the system. For this exploitation method, bash completion must be enabled to gain code execution. This exploitation method will leave an Apache James mail object artifact in the /etc/bash_completion.d directory and the malicious user account.
