Detailsinfo

A vulnerability classified as problematic was found in Cisco Unified Communications Manager, Unified Communications Manager Session Management Edition and Unity Connection (Unified Communication Software) (the affected version is unknown). This vulnerability affects an unknown code. The manipulation with an unknown input leads to a timing discrepancy vulnerability. The CWE definition for the vulnerability is CWE-208. Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not. As an impact it is known to affect confidentiality. CVE summarizes:

A vulnerability in Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection could allow an unauthenticated, remote attacker to perform a timing attack. This vulnerability is due to insufficient protection of a system password. An attacker could exploit this vulnerability by observing the time it takes the system to respond to various queries. A successful exploit could allow the attacker to determine a sensitive system password.

The weakness was shared 07/07/2022 as cisco-sa-ucm-timing-JVbHECOK. The advisory is shared for download at tools.cisco.com. This vulnerability was named CVE-2022-20752 since 11/02/2021.
