Name of the Vulnerable Software and Affected Versions Teltonika firmware version 00.02.02

Description The issue is related to insufficient output sanitization, allowing a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks. This is achieved by injecting malicious client-side code into the 'URL/ Host / Connection' form in the 'DATA TO SERVER' configuration section.

Recommendations For Teltonika firmware version 00.02.02, as a temporary workaround, consider restricting access to the 'DATA TO SERVER' configuration section until a patch is available. Avoid using the 'URL/ Host / Connection' form in this section to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
