Detailed vulnerability description
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists in the handling of bozohttpd special files due to a missing check against .htpasswd itself in some cases. A remote attacker can access contents of certain special files including configuration files for bozohttpd(8) and include the standard .htpasswd file for HTTP Basic Authorisation (RFC-7617), which contains both a list of user names and their encrypted passwords.
