Estado: AnalizadaAlta (7.5)—

Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier downloads a JAR file specified by URL twice, confirming the approval of the first download and loading the classpath entries from the second, allowing attackers able to define classpath entries to execute arbitrary code in the context of the Jenkins controller JVM.

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.

Vulnerability in Jenkins plugin requires network access (AV:N) and authentication (PR:L) to exploit malicious JAR downloads, enabling arbitrary code execution via compromised supply chain/classpath injection mechanism.

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.
