Operationally, ranked in the top 9.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2023-51576 is a deserialization of untrusted data vulnerability in Voltronic Power ViewPower that permits remote code execution. The flaw resides in the product's RMI interface, which listens on TCP port 51099 by default, and results from missing validation of attacker-supplied data before it is deserialized. The issue carries a CVSS score of 9.8 and is tracked as CWE-502; it was originally reported as ZDI-CAN-22012.
Unauthenticated remote attackers can send crafted data to the RMI listener and achieve arbitrary code execution with SYSTEM privileges on affected installations. No user interaction or credentials are required for successful exploitation.
The vulnerability was publicly disclosed in Zero Day Initiative advisory ZDI-23-1882. Its EPSS score has remained flat at 0.0580 with no material increase since publication.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
