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 · unedited
Emerson Electric's Proficy Machine Edition Version 9.00 and prior is vulenrable to CWE-353 Missing Support for Integrity Check, and has no authentication or authorization of data packets after establishing a connection for the SRTP protocol.

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 confidence

Proficy Machine Edition Version 9.00 and prior uses the SRTP (Secure Real-time Transport Protocol) but lacks integrity verification (CWE-353), allowing attackers to modify or inject packets without detection after the initial connection is established. This stems from missing cryptographic integrity checks on data packets, enabling man-in-the-middle attacks and unauthorized command injection in the industrial automation context.

MitigationApply vendor-supplied patches when available; otherwise implement network segmentation to isolate affected systems and deploy additional authentication layers around SRTP communications as compensating controls.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Proficy Machine Edition installation
    Locate the Proficy Machine Edition installation directory and confirm the product is present on the system
    Affected if Proficy Machine Edition is installed on the system
  2. Determine installed version
    Check the version of Proficy Machine Edition using the product's about dialog, version info file, or installation metadata
    Affected if The installed version is 9.00 or any version prior to 9.00 (9.0.0 or lower)
  3. Verify SRTP is in use
    Inspect network traffic captures or configuration settings to confirm SRTP (Secure Real-time Transport Protocol) is enabled for communications
    Affected if SRTP is actively used for real-time transport of data between systems
  4. Inspect SRTP integrity configuration
    Review SRTP configuration settings or protocol documentation to determine whether cryptographic integrity verification (such as SRTP authentication tags or message authentication codes) is configured
    Affected if SRTP is in use and integrity verification is not explicitly configured or is disabled

A system is affected if it runs Proficy Machine Edition version 9.00 or prior and uses SRTP without proper integrity verification configured.

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.

Interim mitigation

Apply vendor-supplied patches when available; otherwise implement network segmentation to isolate affected systems and deploy additional authentication layers around SRTP communications as compensating controls.
