Technical details
A privilege escalation vulnerability exists in the 'chsh' (change shell) utility within HP-UX versions 9.X through 10.20. The flaw resides in the handling of user input or environment variables by the setuid-root executable, allowing a local, unprivileged user to execute arbitrary code or manipulate system files with root authority. An attacker must have local shell access to the system to execute the command. Successful exploitation results in a complete compromise of the host's confidentiality, integrity, and availability. Patches were historically made available by the vendor to address this issue.
