CVE-2025-2817
HighSummary
Mechanizm aktualizacji Thunderbirda pozwalał na to, aby proces użytkownika o średniej integralności mógł ingerować w aktualizator na poziomie SYSTEM, manipulując zachowaniem blokowania plików. Atakujący mógł wstrzyknąć kod do procesu z uprawnieniami użytkownika, co umożliwiało eskalację uprawnień.
Risk Assessment
Podatność ta stwarza ryzyko dla organizacji, ponieważ umożliwia atakującym przejęcie kontroli nad operacjami plikowymi na poziomie SYSTEM, co może prowadzić do poważnych naruszeń bezpieczeństwa.
Recommendation
Zaleca się aktualizację do najnowszych wersji Thunderbirda oraz Firefoksa, aby usunąć tę podatność i zabezpieczyć system przed potencjalnymi atakami.

Original NVD description (English source)
Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Firefox ESR 115.23, Thunderbird 138, and Thunderbird 128.10.
