Name of the Vulnerable Software and Affected Versions Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) (affected versions not specified)

Description The issue is related to insufficient validation of user-supplied input in the XCP Authentication Service, which could allow a remote attacker to cause a denial of service (DoS) condition by sending a specially crafted login message.
