SYSTEM script execution via unauthenticated update manifest
Published Jul 6, 2025 · Updated Jul 7, 2025
Improper manifest authentication in Comodo Internet Security Premium 12.3.4.8162 allows man-in-the-middle attackers to run scripts as SYSTEM. The update client accepts cis_update_x64.xml without checking its authenticity or integrity, then trusts its metadata to retrieve and run update content. An attacker must intercept or redirect update traffic, such as through DNS spoofing; successful exploitation executes attacker-controlled scripts with SYSTEM rights.
