CVE-2021-26596

Name of the Vulnerable Software and Affected Versions Nokia NetAct version 18A

Description A malicious user can modify the filename of an uploaded file to include JavaScript code. This code is then stored and executed by a victim's web browser. The issue can be exploited by including malicious content as a parameter in a URL, which is then posted publicly or e-mailed to victims. Specifically, the /netact/sct API endpoint is used, with the filename parameter being vulnerable.

Recommendations For Nokia NetAct version 18A, consider disabling the ability to upload files or restricting access to the /netact/sct API endpoint until a fix is available. Additionally, avoid using the filename parameter in the affected API endpoint to minimize the risk of exploitation.
