CVE-2023-29080

Estado: AplazadaAlta (8.5)—

Potential privilege escalation vulnerability in Revenera InstallShield versions 2022 R2 and 2021 R2 due to adding InstallScript custom action to a Basic MSI or InstallScript MSI project extracting few binaries to a predefined writable folder during installation time. The standard user account has write access to these files and folders, hence replacing them during installation time can lead to a DLL hijacking vulnerability.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L, PR:L, sin UI:R → escalada local. DLL hijacking en carpeta escribible durante instalación permite ejecutar código con privilegios elevados.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
