CVE-2012-1854

Estado: AnalizadaAlta (7.8)⚠ Explotación activa

Untrusted search path vulnerability in VBE6.dll in Microsoft Office 2003 SP3, 2007 SP2 and SP3, and 2010 Gold and SP1; Microsoft Visual Basic for Applications (VBA); and Summit Microsoft Visual Basic for Applications SDK allows local users to gain privileges via a Trojan horse DLL in the current working directory, as demonstrated by a directory that contains a .docx file, aka "Visual Basic for Applications Insecure Library Loading Vulnerability," as exploited in the wild in July 2012.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vulnerabilidad de búsqueda insegura en DLL (CWE-426) que permite escalada local (AV:L/PR:N) mediante trojan DLL en directorio actual. Impacta con secuestro de carga de bibliotecas y ejecución de código arbitrary con privilegios elevados (C:H/I:H/A:H).

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.
