1) Improper certificate validation

EUVDB-ID: #VU97150

Risk: Low

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

CVE-ID: CVE-2024-8096

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to curl might fail to detect some OCSP problems when configured to use the Certificate Status Request TLS extension. A remote attacker can bypass OCSP stapling protection and perform a Man-in-the-Middle (MitM) attack.

Successful exploitation of the vulnerability requires that curl is build to use GnuTLS library.

Mitigation

Update the affected package curl to the latest version.
