EPSS · scored 2026-10-27

A vulnerability has been identified in SiPass integrated AC5102 (ACC-G2) (All versions < V6.4.9), SiPass integrated ACC-AP (All versions < V6.4.9). Affected devices improperly sanitize input for the pubkey endpoint of the REST API. This could allow an authenticated remote administrator to escalate privileges by injecting arbitrary commands that are executed with root privileges.
