CVE-2025-11739
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCWE‑502: Deserialization of Untrusted Data vulnerability exists that could cause arbitrary code execution with administrative privileges when a locally authenticated attacker sends a crafted data stream, triggering unsafe deserialization.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA CWE-502 deserialization vulnerability in the affected product allows a locally authenticated attacker to send a crafted data stream that triggers unsafe deserialization, resulting in arbitrary code execution with administrative privileges.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if an affected Schneider Electric product is installedLocate Schneider Electric Ecostruxure Power Monitoring Expert or Ecostruxure Power Operation software on the system using standard software inventory or program listing methodsAffected if Either product is present on the system
-
Check the installed version of Power Monitoring ExpertUse the product's version information utility, about dialog, or system registry to determine the exact version number (such as 2022, 2023, or 2024)Affected if The version is 2022, 2023, or 2024
-
Check the installed version of Power OperationUse the product's version information utility, about dialog, or system registry to determine the exact version number (such as 2022 or 2024)Affected if The version is 2022 or 2024
-
Verify local authentication access to the systemConfirm whether untrusted local user accounts exist or whether the application accepts deserialized data streams from external sourcesAffected if A locally authenticated attacker can send crafted data to the application OR the application deserializes untrusted input from any source
The environment is affected if either Ecostruxure Power Monitoring Expert (versions 2022-2024) or Ecostruxure Power Operation (versions 2022 or 2024) is installed AND an attacker with local authentication can send deserialized data streams to the application.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement safe deserialization by validating all input data streams, using safe serialization libraries, and applying allowlist-based type checking before deserializing untrusted data.
