EUVDB-ID: #VU45214

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2010-4764

CWE-ID: CWE-255 - Credentials Management

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Open Ticket Request System (OTRS) before 2.4.10, and 3.x before 3.0.3, does not present warnings about incoming encrypted e-mail messages that were based on revoked PGP or GPG keys, which makes it easier for remote attackers to spoof e-mail communication by leveraging a key that has a revocation signature.

Mitigation

Install update from vendor's website.
