Summary
A vulnerability in the Remote Mobile Access Subsystem in Cisco Unified
Communications Manager (Cisco Unified CM) could allow an unauthenticated,
remote attacker to supply a crafted Transport Layer Security (TLS) certificate
that may be accepted by the affected device.
The vulnerability is due to improper validation of the SAN field of a TLS
certificate. An attacker could exploit this vulnerability by impersonating a
VCS core device and supplying a certificate signed by a certificate authority
trusted by the Cisco Unified CM that contains crafted values in the SAN field.
