Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU16501

Risk: Low

CVSSv4.0: 6.6 [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]

CVE-ID: N/A

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

NetBSD: 7.1 - 8.0

CVE-ID: N/A

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
