CVE-2023-31412: The LMS5xx uses weak hash generation methods, resulting in the creation of insecure hashs.

The LMS5xx uses weak hash generation methods, resulting in the creation of insecure hashs. If an attacker manages to retrieve the hash, it could lead to collision attacks and the potential retrieval of the password.

Security readout for executives and security teams

Plain-English summary

SICK LMS5xx devices reportedly use weak password-hash generation. If an attacker obtains a stored hash, the weakness could help recover the password, creating a serious confidentiality risk for exposed devices.

Executive priority

Prioritize this for environments where LMS5xx devices are network-accessible or support safety, operational, or sensitive sensing workflows. The issue is high severity, but active exploitation is not evidenced in the provided sources.

Technical view

CVE-2023-31412 affects SICK AG LMS5xx in all firmware versions listed in the CVE bundle. The issue is weak hash generation, rated CVSS 3.1 7.5 with network attack vector, no privileges, no user interaction, and high confidentiality impact.

Likely exposure

Organizations using SICK LMS5xx devices should assume affected exposure, especially where device management or data paths are reachable from untrusted networks. The bundle does not identify specific firmware exceptions.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Risk depends on whether attackers can retrieve hashes and then use the weak hashing to recover credentials.

Researcher notes

The key unknown is how hashes can be retrieved in real deployments. The CVE supports weak hashing and possible password recovery after hash access, but the bundle does not provide exploit status, CWE mapping, or confirmed patch details.

Mitigation direction

  • Check SICK PSIRT and advisory SCA-2023-0007 for current vendor guidance.
  • Treat all LMS5xx firmware versions as affected until verified otherwise.
  • Restrict LMS5xx network reachability to trusted management networks only.
  • Rotate related credentials if hash exposure is suspected or confirmed.
  • Monitor for unauthorized access attempts against LMS5xx management interfaces.

Validation and detection

  • Inventory SICK LMS5xx assets and record firmware versions.
  • Confirm whether any LMS5xx interfaces are reachable from untrusted networks.
  • Review SICK advisory SCA-2023-0007 for affected-status and remediation details.
  • Check logs for suspicious authentication or configuration access.
  • Document compensating controls where vendor remediation is unavailable or pending.
