On 08/13/2024, Zoom issued security advisories urging users to patch two high severity vulnerabilities: CVE-2024-39818 (CVSSv3: 7.5), an information disclosure vulnerability that allows an authenticated user to perform information disclosure through network access and CVE-2024-39825 (CVSSv3: 8.5), a buffer overflow that allows an authenticated user to conduct an escalation of privilege using network access. The affected applications are Zoom Workplace Desktop App, Zoom Workplace VDI Client, Zoom Workplace App for Android and iOS, and Zoom Rooms Application for Windows, Mac, and iPad.
Only attackers authenticated to one of the affected Zoom applications could exploit these vulnerabilities, but if exploited, the vulnerabilities would enable an attacker to perform information disclosure and/or privilege escalation on the affected system. No evidence exists indicating the bugs were exploited or that proof-of-concept code is publicly available.

CVE-2024-39825
Applying the latest updates as advised by the vendor is the remediation method. Zoom also has auto-update features in place which could be enabled to keep these applications up-to-date
Patch: We advise you to update the affected application(s) to the latest version at a normal priority. These vulnerabilities are not very high risk and can be mitigated through multifactor authentication.
Auto-update: It is always advised to implement automation to help with vulnerability remediation. In this case, setting up auto updating for these applications will assist in expediting any type of patch these applications would experience. This should be discussed with leadership in your organization as not every application should be patched automatically.
