Description
This security bulletin contains information about 2 vulnerabilities.
1) Information disclosure (CVE-ID: N/A)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
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.

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 improper checking the return value of bozo_check_special_files(). 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.
