CVE-2022-20752Network attack vector

System password disclosure via response timing

Published Jul 6, 2022 · Updated Nov 1, 2024

Timing side channel in Cisco Unified Communications Manager 12.5(1) and 14 allows remote attackers to recover a sensitive system password. Password-related queries produce response-time differences that disclose information about the protected value, although Cisco has not named the affected component. The default configuration is exposed without authentication; Cisco reports password disclosure only, with no integrity or availability impact.
