Security readout for executives and security teams
Plain-English summary
This issue affects Schneider Electric MGE UPS and STS management cards. Under specific web-server settings, administrative account data can be transmitted in cleartext, letting a remote attacker discover credentials if they can reach the device management interface.
Executive priority
Treat this as a priority for facilities, data center, and industrial environments because it can expose administrative access to UPS management systems. Urgency depends on network reachability and whether SSL is disabled.
Technical view
CVE-2018-7246 is a cleartext transmission flaw in Schneider Electric 66074 MGE Network Management Card Transverse, part number SF66074, installed in listed MGE UPS products. The integrated web server on TCP 80/443 can expose administrative account data when SSL is not enabled and the Access Control page is requested repeatedly.
Likely exposure
Exposure is most likely where affected MGE UPS or STS management cards are reachable from user networks, vendor networks, or the internet, and where SSL is disabled or default web settings remain in use.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The risk is credential disclosure through cleartext web traffic, which can affect power infrastructure management if administrative accounts are exposed.
Researcher notes
Evidence is limited to the CVE record and Schneider advisory reference. No CVSS, CWE, patch version, or exploit-in-the-wild evidence is included in the supplied bundle, so exposure validation should focus on asset presence, web reachability, and SSL configuration.
Mitigation direction
- Review Schneider Electric advisory SEVD-2018-074-01 for vendor guidance.
- Restrict access to UPS management interfaces to trusted administration networks.
- Enable SSL/TLS for the management web interface where supported.
- Rotate administrative credentials after securing management access.
- Remove affected devices from direct internet exposure.
Validation and detection
- Inventory Schneider Electric MGE cards with part number SF66074.
- Map installations against the listed MGE Galaxy, EPS, Comet, and STS products.
- Confirm whether management web interfaces are reachable on TCP 80 or 443.
- Check whether SSL is disabled or default web settings remain active.
- Review monitoring for repeated Access Control page access.
