Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco Unified Communications Manager is affected by an XML external entity (XXE) vulnerability. This is due to an incorrectly configured XML parser accepting XML external entities from an untrusted source. An unauthenticated, remote attacker can exploit this, via specially crafted XML data, to disclose sensitive information, or cause the application to consume available resources which would result in Denial of Service.
