Overview

CVE-2023-5422 is a high-severity vulnerability. It was published on October 16, 2023 and has a CVSS 3.1 base score of 8.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.7, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The functions to fetch e-mail via POP3 or IMAP as well as sending e-mail via SMTP use OpenSSL for static SSL or TLS based communication. As the

SSL_get_verify_result() function is not used the certificated is trusted always and it can not be ensured that the certificate

satisfies all necessary security requirements.

This could allow an

attacker to use an invalid certificate to claim to be a trusted host,

use expired certificates, or conduct other attacks that could be

detected if the certificate is properly validated.

This issue affects OTRS: from 7.0.X before 7.0.47, from 8.0.X before 8.0.37; ((OTRS)) Community Edition: from 6.0.X through 6.0.34.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
