CVE-2019-1678

Name of the Vulnerable Software and Affected Versions Cisco Meeting Server versions prior to 2.4.3

Description A vulnerability in Cisco Meeting Server could allow an authenticated, remote attacker to cause a partial denial of service to Cisco Meetings application users who are paired with a Session Initiation Protocol (SIP) endpoint. The issue is due to improper validation of coSpaces configuration parameters. An attacker could exploit this by inserting crafted strings in specific coSpace parameters, potentially preventing clients from joining a conference call in the affected coSpace.

Recommendations For versions prior to 2.4.3, update to version 2.4.3 or later to resolve the issue. As a temporary workaround, consider restricting access to coSpace configuration parameters to minimize the risk of exploitation.
