Video walkthrough for the new @RealTryHackMe "PwnKit" Room by MuirlandOracle. We'll investigate, exploit and mitigate the recently discovered memory corruption vulnerability (read/write out-of-bounds) in Polkit's pkexec, a SUID-root program that is installed by default on every major Linux distribution. This easily exploited vulnerability (CVE-2021-4034) allows any unprivileged user to gain full root privileges on a vulnerable host by exploiting this vulnerability in its default configuration. Hope you enjoy 🙂 #TryHackMe #PwnKit #Polkit #pkexec #CVE-2021-4034
