SSTI

Sandworm is a medium linux box featuring a website with functionality for PGP operations, one of which is vulnerable to SSTI and leads to a restricted shell. Within the firejail environment, I discovered user credentials allowing me to pivot to a SSH shell. Next, I hijacked a cargo crate for command execution to get an unrestricted shell as the previous user. Finally, I exploit a vulnerable version of firejail to root privileges.
