Technical details

The vulnerability is caused by improper handling of parameters (CWE-233) within the Keycloak interface of the Arqit SKA-Platform. Specifically, the tenant web management interface ignores the session idle timeout values defined in Keycloak. An attacker with physical access to a victim's machine can exploit this by utilizing an unexpired browser session that should have been terminated. This allows for the impersonation of an authenticated tenant user. The issue is fixed in version 26.03.
