Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) CRLF injection

EUVDB-ID: #VU105794

Risk: Low

CVSSv4.0: 0.6 [CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-25184

CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')

Exploit availability: No

Description

The vulnerability allows a remote user to manipulate data log entries.

The vulnerability exists due to insufficient validation of attacker-supplied data in Rack::CommonLogger. A remote user can pass specially crafted authorization credentials containing CR-LF characters to the Rack::Auth::Basic method, which stores this info into the to the env['REMOTE_USER'] variable. If the application accepts CR-LF characters in user name, a remote user can manipulate data log entries.

Mitigation

Update the affected package rubygem-rack-1_6 to the latest version.

Vulnerable software versions
