Security readout for executives and security teams
Plain-English summary
This issue affects Linksys E1200 v2 router firmware identified in the source bundle. An unauthenticated remote attacker could send crafted HTTP requests that overflow memory in the router web service, potentially causing denial of service or code execution. Public evidence does not show active exploitation or a confirmed vendor fix.
Executive priority
Treat this as a moderate-priority perimeter device issue. Prioritize discovery and exposure reduction, especially for internet-reachable routers, while waiting for confirmed vendor remediation details.
Technical view
CVE-2025-60693 is a stack-based buffer overflow in get_merge_mac within the Linksys E1200 v2 httpd binary. The vulnerable logic concatenates multiple user-controlled CGI parameters into a fixed-size buffer without proper bounds checking. The record assigns CVSS 3.1 score 6.5 and CWE-121.
Likely exposure
Exposure is most likely where Linksys E1200 v2 routers running firmware E1200_v2.0.11.001_us expose the web management interface to untrusted networks. The source bundle does not provide CPEs, broader version ranges, or enterprise prevalence data.
Exploitation context
The source bundle says exploitation is remote, unauthenticated, and HTTP-based, with possible arbitrary code execution or denial of service. It does not cite CISA KEV listing, active exploitation, a public exploit campaign, or confirmed weaponized use.
Researcher notes
The record has incomplete affected-product metadata despite a specific device and firmware in the description. There is also tension between arbitrary-code-execution wording and the CVSS impacts. Validate against the linked technical report and vendor information before expanding scope.
Mitigation direction
- Check Linksys guidance for fixed firmware or replacement advice.
- Remove internet exposure from router HTTP management interfaces.
- Restrict management access to trusted administrative networks only.
- Replace unsupported devices if no vendor-supported fix is available.
- Monitor perimeter logs for unusual router management access attempts.
Validation and detection
- Inventory Linksys E1200 v2 routers in managed environments.
- Confirm whether firmware E1200_v2.0.11.001_us is installed.
- Verify management interfaces are not reachable from the internet.
- Check vendor support pages for current advisory or firmware status.
- Document any compensating access controls around router administration.

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.
