Security readout for executives and security teams
Plain-English summary
Older Schneider Electric Wonderware Information Server Portal versions used weak encryption for stored credentials. A remote attacker could read a credential file and recover sensitive information. The issue is high impact for environments where this portal remains deployed, especially if reachable from broader corporate or external networks.
Executive priority
Treat as a high-priority legacy ICS application risk. The main business concern is credential exposure leading to broader access, not direct service disruption. Prioritize discovery, isolation, vendor guidance, and credential rotation if affected systems are found.
Technical view
CVE-2014-2380 is a CWE-326 inadequate encryption strength flaw in Wonderware Information Server Portal 4.0 SP1, 4.5, 5.0, and 5.5. The CVSS v2 vector is AV:N/AC:L/Au:N/C:C/I:N/A:N, indicating remote, unauthenticated confidentiality compromise through credential-file exposure.
Likely exposure
Exposure is likely limited to organizations still running the listed legacy Wonderware Information Server Portal versions. Systems outside versions 4.0 SP1, 4.5, 5.0, and 5.5 are not identified as affected in the bundle.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. It does state remote attackers can obtain sensitive information by reading a credential file, so internet or broadly network-reachable deployments increase concern.
Researcher notes
Evidence is strong for affected product, versions, weakness class, and remote confidentiality impact. The provided bundle is sparse on exact remediation and does not substantiate active exploitation. Avoid assuming affected CPEs, patch levels, or exploit availability beyond the cited sources.
Mitigation direction
- Check Schneider Electric and CISA guidance for vendor-approved updates or compensating controls.
- Remove or upgrade affected WIS Portal versions where still present.
- Restrict access to WIS Portal from untrusted networks pending vendor remediation.
- Review credential handling and rotate exposed credentials if compromise is suspected.
Validation and detection
- Inventory Wonderware Information Server Portal deployments and record exact versions.
- Confirm whether any deployment matches 4.0 SP1, 4.5, 5.0, or 5.5.
- Validate network reachability from external and corporate user segments.
- Verify vendor remediation or documented compensating controls are applied.
- Assess whether affected credential files were accessible beyond required service accounts.

Inadequate Encryption Strength
Inadequate Encryption Strength represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
