CVE-2016-7144
The m_authenticate function in modules/m_sasl.c in UnrealIRCd before 3.2.10.7 and 4.x before 4.0.6 allows remote attackers to spoof certificate fingerprints and consequently log in as another user via a crafted AUTHENTICATE parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
