Arbitrary Code Execution in Commvault CommCell by Commvault

CVE-2021-34994

What is CVE-2021-34994?

This vulnerability enables remote attackers to execute arbitrary code on vulnerable instances of Commvault CommCell 11.22.22. Although the exploitation requires authentication, the existing authentication mechanism can be bypassed. The root cause of this vulnerability lies within the DataProvider class, where there is inadequate validation of user-supplied input before it is executed as JavaScript code. This allows an attacker to escape the JavaScript sandbox, leading to the potential execution of Java code with elevated privileges in the context of NETWORK SERVICE.
