CVE-1999-1266

Summary

CVE-1999-1266 is a vulnerability affecting the rsh daemon (rshd), where different error messages are generated based on the validity of provided usernames. This issue allows remote attackers to distinguish valid user accounts on a targeted system, potentially facilitating further exploitation attempts. Despite identical inputs for valid and invalid usernames, rshd reveals sensitive information about system users, making it crucial for affected systems to be updated with a patch or configuration change.
