Descriptions

Insecure Deseralization of untrusted data remote code execution vulnerability was discovered in Patch Manager Orion Platform Integration module and reported to us by ZDI. An Authenticated Attacker could exploit it by executing WSAsyncExecuteTasks deserialization of untrusted data.

Se ha detectado una vulnerabilidad de ejecución de código remota en una Deserialización de datos no confiables en el módulo de integración de la plataforma Orion de Patch Manager y nos fue reportada por ZDI. Un atacante autenticado podría explotarla al ejecutar la deserialización de datos no confiables de WSAsyncExecuteTasks

This vulnerability allows remote attackers to execute arbitrary code on affected installations of SolarWinds Patch Manager. Authentication is required to exploit this vulnerability.
The specific flaw exists within the WSAsyncExecuteTasks endpoint. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE.
