Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is OS Command Injection (CWE-78) in StruxureWare Data Center Expert versions 7.8.1 and prior, exploitable remotely over the network with high privileges — monitor for anomalous OS command execution originating from the DCE application process ↗
- →Attack vector is network-based with low attack complexity and high privilege requirement (AV:N/AC:L/PR:H) — alert on unexpected privileged remote sessions or API calls to StruxureWare Data Center Expert that spawn child processes ↗
- →No known public exploits exist at time of advisory — prioritize detection of novel/custom exploitation attempts against StruxureWare DCE V7.8.1 and prior ↗
- ·Affected versions are StruxureWare Data Center Expert V7.8.1 and prior; no fixed version was released at time of advisory — verify patch status before assuming remediation ↗
- ·A companion path traversal vulnerability (CVE-2021-22794, CWE-22) exists in the same product and versions with the same CVSS score — both should be assessed together as they may be chained for exploitation ↗
