CVE-2016-7143

Name of the Vulnerable Software and Affected Versions Charybdis versions prior to 3.5.3

Description The issue allows remote attackers to spoof certificate fingerprints, enabling them to log in as another user. This is achieved by crafting the AUTHENTICATE parameter. The m authenticate function in modules/m sasl.c is specifically vulnerable to this type of attack.

Recommendations For versions prior to 3.5.3, update to version 3.5.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the m authenticate function until a patch is applied. Avoid using the crafted AUTHENTICATE parameter in the affected module until the issue is resolved.
