Command Injection in Seowon Intech SWC-9100 diagnostic.cgi ping functionality

IdentifiersCVE-2013-7179CWE-77

CVE-2013-7179 is an unauthenticated command-injection vulnerability in the web management interface of Seowon Intech SWC-9100 and related SWU-9100 WiMAX mobile routers. The flaw is present in the ping diagnostic functionality exposed through cgi-bin/diagnostic.cgi, where attacker-controlled input supplied via the ping_ipaddr parameter is incorporated into a shell command without proper neutralization of shell metacharacters. Because the application passes unsanitized user input into an operating-system command context, a remote attacker can append arbitrary shell syntax and cause unintended command execution on the device.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote unauthenticated attacker to execute arbitrary commands on the router through the web interface. This can lead to full compromise of the device's confidentiality, integrity, and availability, including unauthorized system manipulation, service disruption, use of the router as a foothold for further network activity, and in related exposed functionality the ability to reboot the device or trigger a factory reset.

Mitigation

If you can’t patch tonight, do this now.

Restrict management access so that only trusted administrative sources can reach the web interface. Disable web administration from the WAN interface and enforce firewall rules that prevent untrusted remote access to the management service. Where possible, place device administration behind a trusted internal network or secured administrative channel and retire unsupported or end-of-life equipment.

Remediation

Patch, then assume compromise.

No practical vendor fix or solution was known at the time of publication. The appropriate long-term remediation is to apply a vendor firmware update if one becomes available or replace the affected device with supported hardware that receives security updates. From a secure-development perspective, the vulnerable diagnostic feature should be rewritten to avoid shell command construction from web input and instead invoke system utilities using argument-vector execution with strict allowlisting of expected parameters.
