Summary

  o A vulnerability in the audit logging component of Cisco Unified
    Communications Manager, Cisco Unified Communications Manager Session
    Management Edition, Cisco Unified Communications Manager IM & Presence
    Service, Cisco Unity Connection, Cisco Emergency Responder, and Cisco Prime
    License Manager could allow an authenticated, remote attacker to view
    sensitive information in clear text on an affected system.

    The vulnerability is due to the storage of certain unencrypted credentials.
    An attacker could exploit this vulnerability by accessing the audit logs on
    an affected system and obtaining credentials that they may not normally
    have access to. A successful exploit could allow the attacker to use those
    credentials to discover and manage network devices.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.
