CVE-2025-42976

Estado: AplazadaAlta (8.1)—

SAP NetWeaver Application Server ABAP (BIC Document) allows an authenticated attacker to craft a request that, when submitted to a BIC Document application, could cause a memory corruption error. On successful exploitation, this results in the crash of the target component. Multiple submissions can make the target completely unavailable. A similarly crafted submission can be used to perform an out-of-bounds read operation as well, revealing sensitive information that is loaded in memory at that time. There is no ability to modify any information.

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:N, PR:L, UI:N indica explotación remota autenticada de servicio (T1210). Memory corruption causa DoS (T1499.004); out-of-bounds read permite lectura de datos en memoria (T1005).

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.
