Description

The IP Phone Personal Address Book (PAB) Synchronizer feature in Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 4.1, 4.2 before 4.2(3)SR4b, 4.3 before 4.3(2)SR1b, 5.x before 5.1(3e), 6.x before 6.1(3), and 7.0 before 7.0(2) sends privileged directory-service account credentials to the client in cleartext, which allows remote attackers to modify the CUCM configuration and perform other privileged actions by intercepting these credentials, and then using them in requests unrelated to the intended synchronization task, as demonstrated by (1) DC Directory account credentials in CUCM 4.x and (2) TabSyncSysUser account credentials in CUCM 5.x through 7.x.
