Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Improper Encoding or Escaping of Output

EUVDB-ID: #VU102870

Risk: Low

CVSSv4.0: 0.2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-50349

CWE-ID: CWE-116 - Improper Encoding or Escaping of Output

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect handling of control sequences in account names when asking for credentials. A remote attacker can trick the victim into clicking on a specially crafted URL and trick users into providing passwords for trusted Git hosting sites when in fact they are then sent to untrusted sites that are under the attacker's control.

Mitigation

Install updates from vendor's repository.
