Security readout for executives and security teams
Plain-English summary
CVE-2025-60694 affects Linksys E1200 v2 router firmware and may let an unauthenticated remote attacker crash the device. The source description also claims possible arbitrary code execution, but the supplied CVSS scoring only rates availability impact. Treat exposed management interfaces as the main business risk.
Executive priority
Prioritize any internet-exposed or business-critical E1200 v2 routers. The practical urgency is high for exposed devices because unauthenticated remote denial of service is supported by the scoring, while code execution is less firmly evidenced in the supplied data.
Technical view
The issue is a CWE-121 stack-based buffer overflow in the httpd validate_static_route function. User-controlled static-route CGI parameters are concatenated into fixed-size stack buffers without adequate bounds checks. The provided record names firmware E1200_v2.0.11.001_us.tar.gz on Linksys E1200 v2 routers.
Likely exposure
Organizations are most exposed if Linksys E1200 v2 router administration or HTTP management is reachable from untrusted networks. The structured affected-product fields are incomplete, so confirm device model and firmware directly.
Exploitation context
The bundle says exploitation is remote, unauthenticated, low complexity, and needs no user interaction. It is not listed as CISA KEV, and the provided sources do not establish active exploitation in the wild.
Researcher notes
Evidence is limited. The description asserts arbitrary code execution or denial of service, but CVSS only marks availability impact. The affected CPE fields are empty, so validation should rely on model, firmware, and vendor or researcher references rather than automated CPE matching alone.
Mitigation direction
- Inventory Linksys E1200 v2 routers and record firmware versions.
- Check Linksys guidance for fixed firmware, retirement status, or replacement advice.
- Block WAN or untrusted access to router HTTP management interfaces.
- Restrict administration to trusted networks or VPN-only paths.
- Replace affected routers if no supported vendor fix exists.
Validation and detection
- Confirm whether any Linksys E1200 v2 devices run E1200_v2.0.11.001_us.tar.gz.
- Review perimeter exposure for router web administration services.
- Check firewall rules for untrusted access to management HTTP endpoints.
- Review logs for abnormal static-route configuration requests or router crashes.
- Track CVE and Linksys references for updated remediation guidance.

Stack-based Buffer Overflow
Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
