Title: Majordomo Local -C Parameter Vulnerability
Severity: MODERATE
Description:
It is possible for a local user to gain majordomo privileges through a vulnerability which allows privileged arbitrary commands to be executed. If the -C parameter is passed to majordomo (or one of several other scripts) when run with the setuid root wrapper, the argument to -C will be executed with majordomo privileges.
This occurs on several scripts: archive2.pl, bounce-remind, config-test, digest, majordomo, request-answer and resend. medit under bin/, and archive_mh.pl, new-list, and sequencer under Tools/ uses 'require' in the same way, but since the wrapper only executes those scripts found in the majordomo installation directory, they cannot be exploited.
Affected Products:
- Great Circle Associates Majordomo 1.94.4
