CVE-2022-23450

Status: ModifiedCritical (9.8)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
