Background
FreeTAKServer-UI is a PyPI package that provides a user interface for FreeTAKServer, a tactical messaging server used for military and emergency response operations. It allows users to manage and monitor the server, as well as interact with the deployed TAK devices. FreeTAKServer-UI version 1.9.8 has been found to have a stored cross-site scripting (XSS) vulnerability. This vulnerability can be exploited through the Callsign parameter, potentially allowing an attacker to inject malicious scripts into the application and execute them within the context of other users' browsers.
Vulnerability Detail
The stored cross-site scripting (XSS) vulnerability in FreeTAKServer-UI version 1.9.8 arises from inadequate input sanitization of the Callsign parameter. An attacker can craft a malicious payload and inject it into the application, which will be stored and executed when other users access the affected page. This can lead to various security risks, including session hijacking, data theft, and unauthorized actions performed on behalf of the user. The vulnerability has a CVSS score of 5.4, indicating a moderate severity level.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, users can manually sanitize the Callsign parameter before passing it to the application. This can be achieved by implementing proper input validation and sanitization techniques, such as HTML entity encoding or using a dedicated library for input sanitization. Here is an example of how to sanitize the Callsign parameter using Python's html module:
import html
callsign = html.escape(callsign)
However, it is strongly recommended to apply the official patch or upgrade to a fixed version of FreeTAKServer-UI as soon as possible.
Conclusion
In conclusion, FreeTAKServer-UI version 1.9.8 is vulnerable to a stored cross-site scripting (XSS) vulnerability. This can be exploited through the Callsign parameter, potentially leading to various security risks. Users are advised to upgrade to a patched version of FreeTAKServer-UI and implement proper input validation and sanitization techniques.
