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
The potential exists for exposure of the product's password used to restrict unauthorized access to Rockwell PLC5/SLC5/0x/RSLogix 1785-Lx and 1747-L5x controllers. The potential exists for an unauthorized programming and configuration client to gain access to the product and allow changes to the product’s configuration or program. When applicable, upgrade product firmware to a version that includes enhanced security functionality compatible with Rockwell Automation's FactoryTalk Security services.

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 · high confidence

Hardcoded or exposed passwords in Rockwell PLC5, SLC5, and 1747-L5x controllers allow unauthorized programming and configuration clients to bypass access controls, potentially modifying controller programs and configurations.

MitigationUpgrade controller firmware to versions with enhanced security functionality compatible with Rockwell Automation's FactoryTalk Security services.

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 PLC5 and SLC5 controller models in use
    Inventory the physical PLC hardware or review network scan results to determine if PLC5 1785-Lx or SLC5/01 1747-L5x controllers are present in the environment
    Affected if Any PLC5 1785-Lx or SLC5/01 1747-L5x controllers are found in the environment, they are affected since all firmware versions are vulnerable
  2. Identify Rslogix software installations
    List installed software on engineering workstations and programming consoles to identify Rslogix installations used for these controllers
    Affected if Rslogix is installed and used to program the affected PLC models, the vulnerability applies
  3. Check for default or unchanged passwords
    Review PLC configuration settings and access control lists to determine if default passwords remain in place or if passwords are hardcoded in the controller configuration
    Affected if Default, hardcoded, or exposed passwords are configured or no password protection is enforced on the controller programming interface
  4. Assess network exposure of controllers
    Review network segmentation and firewall rules to determine if the PLC controllers are accessible from unauthorized network segments or external networks
    Affected if The controllers are reachable from network segments beyond the trusted control system network, allowing unauthorized programming clients to connect

If PLC5 1785-Lx or SLC5/01 1747-L5x controllers are in use with Rslogix and either default passwords are present or the controllers are network-accessible to untrusted hosts, the environment is affected by this vulnerability.
