Command Injection in Zhone zNID GPON 2426A Web Administrative Portal

IdentifiersCVE-2014-9118CWE-78

CVE-2014-9118 is a remote command injection vulnerability in the web administrative portal of Zhone zNID GPON 2426A devices, including related Zhone router series, affecting versions prior to S3.0.501. The flaw is exposed through the zhnping.cmd functionality, where the ipAddr parameter is not properly sanitized before being incorporated into an operating system command. By supplying shell metacharacters in that parameter, an attacker can inject and execute arbitrary commands on the underlying host operating system through the administrative web interface.

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 arbitrary command execution on the affected router’s underlying operating system. This can enable full compromise of the device, including modification of configuration, execution of follow-on payloads, disruption of network services, interception or manipulation of traffic handled by the device, and use of the router as a pivot or botnet node.

Mitigation

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

Restrict access to the web administrative interface to trusted management networks only, and do not expose the administrative portal to the public internet. Apply network-layer access controls, disable remote administration where not required, and segment management access from untrusted users. Monitor administrative interface activity for abnormal use of diagnostic functions such as ping-related features, and rotate credentials if compromise is suspected. Because exploitation results in OS command execution, mitigation should be treated as temporary until patched firmware is deployed.

Remediation

Patch, then assume compromise.

Upgrade affected Zhone devices to a fixed firmware release. The available information indicates that affected versions are those earlier than S3.0.501, and the advisory recommends upgrading to version S3.1.241, which is stated to contain fixes for the reported issues. Firmware management processes should verify that all affected device families are running a vendor-fixed release.
