Critical Remote code execution vulnerability in Palo Alto Networks Cortex XSOAR

Cybersecurity specialists report the detection of a critical vulnerability in Cortex XSOAR, the detection and response platform executed on fully integrated endpoint, network and cloud data developed by Palo Alto Networks.

Tracked as CVE-2021-26701, this flaw exists due to insufficient validation of user input in .NET Core, which would allow remote threat actors to pass specially crafted entries into the vulnerable application.

The vulnerability received a score of 7.1/10 according to the Common Vulnerability Scoring System (CVSS) and its successful exploitation would allow arbitrary code to be executed on the affected system. This flaw resides in all versions of Cortex XSOAR prior to v7.1.3.20270.

Even though the flaws can be exploited by unauthenticated threat actors over the Internet, researchers have not detected any active exploitation attempts. Security patches have already been released, so users of affected deployments are encouraged to update as soon as possible.
