Description

This security bulletin contains information about 1 vulnerability.

1) Input validation error (CVE-ID: CVE-2010-4767)

CWE-ID: CWE-20 - Improper input validation

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

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Open Ticket Request System (OTRS) before 2.3.6 does not properly handle e-mail messages in which the From line contains UTF-8 characters associated with diacritical marks and an invalid charset, which allows remote attackers to cause a denial of service (duplicate tickets and duplicate auto-responses) by sending a crafted message to a POP3 mailbox.

Remediation

Install update from vendor's website.
