CVE-2026-11958
Local privilege escalation in ANSSI’s DFIR-ORC
Description
Local privilege escalation by loading DLLs from a shared temporary directory in ANSSI’s DFIR-ORC, versions 10.2.7 and prior. An attacker with prior access to the system, can place a malicious DLL in C:\Windows\Temp and wait for the application to be executed. Because DFIR-ORC is extracted and executed from that location with administrative privileges, the malicious library can be loaded automatically, allowing the attacker to gain administrator privileges on the affected machine.

Action Type Old Value New Value Added Translation Title: DFIR-ORC de ANSSI, Description: Escalada de privilegios local mediante la carga de DLLs desde un directorio temporal compartido en DFIR-ORC de ANSSI, versiones 10.2.7 y anteriores. Un atacante con acceso previo al sistema puede colocar una DLL maliciosa en [SystemPath]\Temp y esperar a que la aplicación sea ejecutada. Debido a que DFIR-ORC se extrae y ejecuta desde esa ubicación con privilegios administrativos, la biblioteca maliciosa puede cargarse automáticamente, permitiendo al atacante obtener privilegios de administrador en la máquina afectada. -
