CVE-2025-47422
Advanced Installer before 22.6 has an uncontrolled search path element local privilege escalation vulnerability. When running as SYSTEM in certain configurations, Advanced Installer looks in standard-user writable locations for non-existent binaries and executes them as SYSTEM. A low-privileged attacker can place a malicious binary in a targeted folder; when the installer is executed, the attacker achieves arbitrary SYSTEM code execution.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Al ejecutarse como SYSTEM en ciertas configuraciones, el instalador avanzado busca binarios inexistentes en ubicaciones de escritura estándar y los ejecuta como SYSTEM. Un atacante con pocos privilegios puede colocar un binario malicioso en una carpeta específica; al ejecutar el instalador, el atacante ejecuta código SYSTEM arbitrario."
