Name of the Vulnerable Software and Affected Versions Teltonika RTU950 version R 31.04.89

Description The issue allows a user to login without limitation, causing the application to store sessions in memory for every successful login request. This can lead to increased memory use and consumption of free space.

Recommendations For Teltonika RTU950 version R 31.04.89, consider implementing a mechanism to limit the number of concurrent logins or to automatically log out inactive sessions to prevent excessive memory use. As a temporary workaround, restrict the ability for users to re-login without logging out to minimize the risk of exploitation.
