VMware Patches Critical Vulnerabilities in Carbon Black App Control

VMware this week announced software updates that address two critical-severity vulnerabilities in its Carbon Black App Control product.

An application allow listing solution, Carbon Black App Control allows security teams to secure enterprise systems by locking them down to prevent unwanted changes, and to maintain continuous compliance.

VMware this week announced software updates that address two critical-severity vulnerabilities in its Carbon Black App Control product.

An application allow listing solution, Carbon Black App Control allows security teams to secure enterprise systems by locking them down to prevent unwanted changes, and to maintain continuous compliance.

Tracked as CVE-2022-22951, the first of the two security holes is an OS command injection issue that could lead to remote code execution. The flaw exists because user input isn’t properly validated.

An attacker looking to exploit the bug needs to be authenticated as a high-privileged user and requires network access to the App Control interface in order to execute commands on the server.

Tracked as CVE-2022-22952 and described as a file upload vulnerability, the second bug could be exploited by an attacker with administrative access to App Control to upload a specially crafted file and execute arbitrary code.

Both vulnerabilities carry a CVSS score of 9.1 and both have been addressed with the release of Carbon Black App Control versions 8.8.2, 8.7.4, 8.6.6, and 8.5.14.

With no workarounds available for either of the two security defects, administrators are advised to apply the available patches as soon as possible.

VMware makes no mention of either of the two flaws being exploited in malicious attacks. Researcher Jari Jääskelä, who has been credited for reporting both flaws, has confirmed for SecurityWeek that while the vulnerabilities are critical based on their CVSS score, exploitation does require authentication, which means they are less likely to be exploited in the wild.
