Security readout for executives and security teams
Plain-English summary
CVE-2023-35697 affects the SICK ICR890-4. The device does not sufficiently restrict repeated authentication attempts, which could let a remote attacker try many passwords until valid credentials are found. The main business risk is unauthorized access to a device account, with limited confidentiality impact reported by CVSS.
Executive priority
Treat this as a moderate-priority industrial asset hardening issue. Prioritize externally reachable or broadly accessible devices first, then confirm vendor guidance and access controls across internal deployments.
Technical view
The issue is CWE-307: improper restriction of excessive authentication attempts. CVSS 3.1 is 5.3, with network attack vector, low complexity, no privileges, and no user interaction. The listed impact is confidentiality low, with no integrity or availability impact in the supplied CVSS vector.
Likely exposure
Exposure is most relevant where SICK ICR890-4 authentication interfaces are reachable over a network, especially from untrusted segments. The source bundle lists SICK ICR890-4 as affected, but does not provide detailed deployment conditions or fixed versions.
Exploitation context
The source bundle says remote brute-forcing of user credentials is possible. It does not cite active exploitation, and KEV is false. No public exploit status or weaponized procedure is supported by the provided evidence.
Researcher notes
Evidence is limited to the CVE record and SICK references. The affected version is represented as “0” in the bundle, so version interpretation should be confirmed against the SICK CSAF or PSIRT advisory before remediation decisions.
Mitigation direction
- Review SICK PSIRT and advisory SCA-2023-0006 for official remediation guidance.
- Restrict device management access to trusted administrative networks only.
- Place the device behind network controls that limit repeated remote login attempts.
- Use strong, unique credentials for all device accounts.
- Monitor authentication logs for repeated failures or unusual access patterns.
Validation and detection
- Inventory environments for SICK ICR890-4 devices.
- Compare affected product details against SICK advisory SCA-2023-0006.
- Confirm whether authentication interfaces are reachable from untrusted networks.
- Review logs for repeated failed authentication attempts.
- Verify compensating network controls cover all reachable management paths.
