Name of the Vulnerable Software and Affected Versions KTM System e-BOK (affected versions not specified)

Description KTM System e-BOK allows the session identifier to be set by the client before authentication. If a cookie with a valid name is provided, the system does not change its value after a successful login. This behavior allows an attacker to perform session fixation, where a specific session ID is forced upon a victim, enabling the attacker to hijack the authenticated session.

Recommendations Apply the patch published in June 2026.
