Security readout for executives and security teams
Plain-English summary
This issue lets a logged-in attacker save malicious JavaScript in an FS S3150-8T2F administration field. When another user, including an administrator, opens the affected page, the script can run in that user’s browser. The business risk is compromise of management-session data or actions through the switch administration interface.
Executive priority
Treat as high priority for affected network management assets. The issue is not proven actively exploited in the provided evidence, but successful abuse could affect administrator browser sessions and device-management integrity.
Technical view
CVE-2025-25612 is stored XSS in the Time Range Configuration function of FS Inc S3150-8T2F before S3150-8T2F_2.2.0D_135103. The Time Range Name field is improperly sanitized. CVSS 3.1 is 7.1 with network attack vector, low privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure appears limited to organizations running FS S3150-8T2F devices below S3150-8T2F_2.2.0D_135103, especially where the administration interface is reachable by multiple users or broad internal networks.
Exploitation context
The CVE is not listed as KEV in the provided bundle. The record includes a public GitHub reference, but the supplied evidence does not establish active exploitation. Exploitation requires low privileges and another user interaction with the affected administration page.
Researcher notes
The public bundle identifies the vulnerable model and version threshold, but structured affected CPE data is absent. Validate product identity carefully before scoping. Avoid assuming other FS Inc switches are affected without vendor confirmation.
Mitigation direction
- Upgrade affected S3150-8T2F devices to S3150-8T2F_2.2.0D_135103 or later if vendor-supported.
- Restrict switch administration interfaces to trusted management networks only.
- Limit administrative and low-privilege management accounts to necessary personnel.
- Review saved Time Range Name entries for suspicious content.
- Check FS Inc guidance for any additional remediation or cleanup instructions.
Validation and detection
- Inventory FS S3150-8T2F devices and record firmware versions.
- Confirm no device runs firmware earlier than S3150-8T2F_2.2.0D_135103.
- Review Time Range Configuration entries without rendering suspicious values in a browser.
- Check access logs for unusual administration activity around affected pages.
- Verify management interface access controls are enforced.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
