Nokia · Nokia Netact · 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.
