NVD Description

Note: Versions mentioned in the description apply only to the upstream php-horde-groupware package and not the php-horde-groupware package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Horde Groupware v5.2.22 has a user enumeration vulnerability that allows an unauthenticated attacker to determine the existence of valid accounts on the system. To exploit the vulnerability, an HTTP request must be sent to ‘/imp/attachment.php’ including the parameters ‘id’ and ‘u’. If the specified user exists, the server will return the download of an empty file; if it does not exist, no download will be initiated, which unequivocally reveals the validity of the user.
