Security readout for executives and security teams
Plain-English summary
CVE-2025-60690 is a high-severity flaw reported in Linksys E1200 v2 router firmware. An unauthenticated attacker who can reach the router's HTTP service may be able to crash the device or run code by sending malformed web parameters. The source bundle does not show confirmed real-world exploitation.
Executive priority
Treat this as a high-priority edge-device risk where affected routers remain in use. Prioritize internet- or broadly reachable management interfaces first, then plan firmware validation or device replacement if Linksys does not provide a supported fix.
Technical view
The issue is a stack-based buffer overflow in the httpd get_merge_ipaddr function. It concatenates up to four user-controlled CGI parameters into a fixed-size stack buffer without bounds checking. The CVSS v3.1 score is 8.8, with no privileges or user interaction required and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure appears limited to Linksys E1200 v2 routers running firmware E1200_v2.0.11.001_us.tar.gz, based on the CVE description. The structured affected-product and CPE fields are not populated, so asset teams should validate model and firmware directly.
Exploitation context
The bundle states unauthenticated remote attackers can use crafted HTTP requests to cause denial of service or arbitrary code execution. It does not cite public active exploitation, and KEV status is false in the provided data.
Researcher notes
The public record gives a precise function and vulnerability class, but affected CPE metadata is missing. Avoid broad product claims beyond Linksys E1200 v2 firmware named in the description. No source in the bundle establishes active exploitation.
Mitigation direction
- Identify Linksys E1200 v2 devices and confirm firmware versions.
- Check Linksys guidance for fixed firmware or replacement advice.
- Disable remote administration where enabled.
- Restrict router web administration to trusted management networks only.
- Replace unsupported devices if no vendor fix is available.
Validation and detection
- Inventory routers by model, hardware revision, and firmware filename/version.
- Confirm whether HTTP administration is reachable from untrusted networks.
- Review vulnerability scans for CVE-2025-60690 coverage and false negatives.
- Check the provided KEV status during normal vulnerability review.
- Document compensating controls for devices awaiting replacement or update.
