Technical details

The vulnerability exists within the TIOCCONS ioctl function in SunOS 4.1.1. The system fails to perform adequate permission checks when a user requests to redirect console I/O to a different terminal. A local attacker with standard user access can exploit this lack of validation to intercept sensitive console traffic or manipulate system inputs, ultimately facilitating a privilege escalation to root. This is a local attack requiring no special preconditions other than system access. Patch information was historically provided in CERT advisory CA-1990-12.
