JamoDat TSMManager Collector version up to 6.5.0.21 is vulnerable to an Authorization Bypass because the Collector component is not properly validating an authenticated session with the Viewer.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
JamoDat TSMManager Collector version up to 6.5.0.21 is vulnerable to an Authorization Bypass because the Collector component is not properly validating an authenticated session with the Viewer. If the Viewer has been modified (binary patched) and the Bypass Login functionality is being used, an attacker can request every Collector's functionality as if they were a properly logged-in user: administrating connected instances, reviewing logs, editing configurations, accessing the instances' consoles, accessing hardware configurations, etc.Exploiting this vulnerability won't grant an attacker access nor control on remote ISP servers as no credentials is sent with the request.
