Security readout for executives and security teams
Plain-English summary
CVE-2013-3307 affects legacy Linksys E1000, E1200, and E3200 routers. A network attacker could abuse the router ping feature to make the device run unintended operating-system commands. The issue is high risk because the CVSS data indicates no authentication or user interaction is required.
Executive priority
Treat this as a high-priority legacy infrastructure issue. The main business risk is an old edge device becoming an entry point or disruption point. Prioritize inventory, exposure reduction, and replacement or firmware remediation for any affected routers still in service.
Technical view
The vulnerability is CWE-78 OS command injection in apply.cgi through the ping_ip parameter on TCP port 52000. Reported affected firmware ranges are E1000 through 2.1.02, E1200 before 2.0.05, and E3200 through 1.0.04. CVSS 3.1 score is 8.3 with network attack vector, low complexity, no privileges, and no user interaction.
Likely exposure
Exposure is most likely in organizations, small offices, labs, or home offices still running these older Linksys router models. Risk is higher if TCP port 52000 or the affected management functionality is reachable from untrusted networks. Evidence provided does not establish current internet-wide prevalence.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. The vulnerability is still concerning because it is remotely reachable under the CVSS model and affects router firmware, where compromise can disrupt connectivity or support further network abuse.
Researcher notes
The provided evidence is narrow but specific: affected models, firmware boundaries, endpoint, parameter, port, CWE, and CVSS vector are stated. Do not infer broader Linksys exposure, current exploitation, or universal patch availability from this bundle alone.
Mitigation direction
- Inventory Linksys E1000, E1200, and E3200 devices and record firmware versions.
- Upgrade outside the affected firmware range where vendor-supported firmware exists.
- Check Linksys or archived vendor guidance before assuming a fixed version exists.
- Restrict untrusted access to router management services and TCP port 52000.
- Replace unsupported affected routers that cannot receive safe firmware updates.
Validation and detection
- Confirm whether deployed models match E1000, E1200, or E3200.
- Compare firmware versions against the reported affected ranges.
- Verify TCP port 52000 is not reachable from untrusted networks.
- Review firewall and remote administration settings for unnecessary exposure.
- Document compensating controls or replacement plans for unsupported devices.
