Bitbucket Environment Variable Remote Command Injection
Posted Mar 16, 2023
Authored by Shelby Pace, Y4er, Ry0taK | Site metasploit.com

For various versions of Bitbucket, there is an authenticated command injection vulnerability that can be exploited by injecting environment variables into a user name. This module achieves remote code execution as the atlbitbucket user by injecting the GIT_EXTERNAL_DIFF environment variable, a null character as a delimiter, and arbitrary code into a user's user name. The value (payload) of the GIT_EXTERNAL_DIFF environment variable will be run once the Bitbucket application is coerced into generating a diff. This Metasploit module requires at least admin credentials, as admins and above only have the option to change their user name.

Kernel Live Patch Security Notice LSN-0092-1
Posted Mar 8, 2023
Authored by Benjamin M. Romer

Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
