Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions OpenDMARC versions 1.3.2 and earlier OpenDMARC versions 1.4.x through 1.4.0-Beta1

Description The issue is related to a signature-bypass vulnerability, specifically when dealing with multiple From: addresses in email messages. This could impact applications that rely on domain names to determine the origin of an email. The vulnerability might allow a remote attacker to bypass authentication through spoofing, potentially leading to unauthorized access to information and disruption of its integrity and availability.

Recommendations For OpenDMARC versions 1.3.2 and earlier, update to a version that fixes the signature-bypass vulnerability. For OpenDMARC versions 1.4.x through 1.4.0-Beta1, update to a version that fixes the signature-bypass vulnerability. As a temporary workaround, consider restricting the handling of multiple From: addresses in email messages to minimize the risk of exploitation.
