Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-11053

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error when using a .netrc file for credentials and an instruction to follow HTTP redirects. The cURL library can leak credentials intended for the first URL prior to redirection. This however will only occur if the .netrc file has an entry that matches the redirect target hostname but the entry either omits just the password or omits both login and password.

Mitigation

Install updates from vendor's website.
