CVE-2019-1372

Estado: ModificadaCrítica (10)—

An remote code execution vulnerability exists when Azure App Service/ Antares on Azure Stack fails to check the length of a buffer prior to copying memory to it.An attacker who successfully exploited this vulnerability could allow an unprivileged function run by the user to execute code in the context of NT AUTHORITY\system thereby escaping the Sandbox.The security update addresses the vulnerability by ensuring that Azure App Service sanitizes user inputs., aka 'Azure App Service Remote Code Execution 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).
