CRITICAL 9.8

DescriptionNVD

A vulnerability has been identified in SIMATIC Energy Manager Basic (All versions < V7.3 Update 1), SIMATIC Energy Manager PRO (All versions < V7.3 Update 1). The affected system allows remote users to send maliciously crafted objects. Due to insecure deserialization of user-supplied content by the affected software, an unauthenticated attacker could exploit this vulnerability by sending a maliciously crafted serialized object. This could allow the attacker to execute arbitrary code on the device with SYSTEM privileges.

AnalysisAI
