Using sudo for local privilege escalation - Patch your systems!
I recently came across CVE-2025-32463 and it re-emphasized to me the importance of making sure systems are being properly patched. This is a relatively easy exploit where the linux `sudo` utility is used to perform a local privilege escalation attack and gain root access to a vulnerable system. In this post, I'll show how I recreated the POC exploit on multiple flavors of linux as well as what to be on the lookout for if you are in charge of ensuring systems are patched.
