MS-ISAC ADVISORY NUMBER:

2021-039

DATE(S) ISSUED:

03/25/2021

OVERVIEW:

Multiple vulnerabilities have been discovered in Cisco Jabber the most severe of which could allow for arbitrary code execution. Cisco Jabber provides instant messaging (IM), voice, video, voice messaging, desktop sharing, and conferencing on any device. Successful exploitation of the most severe of these vulnerabilities could allow an unauthenticated, remote attacker to execute code on the affected systems. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Applications configured to have fewer restrictions on the system could be less impacted than those who operate with elevated privileges.
