Security readout for executives and security teams
Plain-English summary
CVE-2018-25108 is a denial-of-service issue in listed WAGO controllers. An unauthenticated remote attacker could exhaust controller resources and disrupt availability. The business risk is operational downtime, not data theft, based on the provided CVSS impact.
Executive priority
Prioritize assessment for industrial or building-control environments using these WAGO controllers. The issue can disrupt operations remotely without authentication, but current evidence does not show confirmed active exploitation or data compromise.
Technical view
The CVE describes uncontrolled resource consumption, CWE-770, affecting availability over the network with low attack complexity and no privileges or user interaction. Listed products include WAGO 750-8100, 750-831, 750-880, and 750-889 controllers. The bundle does not provide exploit details or a named fix.
Likely exposure
Exposure is most relevant where the listed WAGO controllers are deployed and reachable over IP networks. Internet or untrusted-network reachability would materially increase concern. The source bundle does not clarify exact firmware ranges beyond version entries shown as 0.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and no cited source states active exploitation. Treat it as a credible remote availability risk, but do not assume exploitation in the wild from this evidence alone.
Researcher notes
The available record is sparse: it gives CWE-770, CVSS 7.5, network attack vector, and affected product names, but no payload details, root cause specifics, firmware matrix, or remediation text. Validate against VDE-2018-013 before drawing product-version conclusions.
Mitigation direction
- Review WAGO/VDE advisory VDE-2018-013 for product-specific guidance.
- Apply vendor-recommended updates or mitigations where confirmed applicable.
- Restrict controller access to trusted operational networks only.
- Prioritize compensating controls if no vendor fix is identified.
- Avoid exposing affected controllers directly to untrusted networks.
Validation and detection
- Inventory deployed WAGO 750-8100, 750-831, 750-880, and 750-889 controllers.
- Compare product and firmware details against WAGO/VDE advisory guidance.
- Confirm whether controllers are reachable from untrusted networks.
- Review availability incidents affecting listed controllers since deployment.
- Document any uncertainty around version applicability.
