Command Injection in TOTOLINK X2000R /boafrm/formWsc

IdentifiersCVE-2025-5504CWE-77· Improper Neutralization of Special…

CVE-2025-5504 is a command injection vulnerability affecting TOTOLINK X2000R firmware version 1.0.0-B20230726.1108. The flaw is present in the /boafrm/formWsc endpoint, where the peerRptPin argument is not properly sanitized before being used by underlying code, allowing attacker-controlled input to be interpreted as operating system commands. The issue is remotely exploitable and public disclosure indicates exploit details are available. Based on the provided content, the vulnerable function or exact code path beyond the /boafrm/formWsc handler and peerRptPin parameter is not available.

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 attacker to inject and execute arbitrary commands on the affected device. This can result in full compromise of the router, including unauthorized administrative control, modification of device configuration, deployment of malware or botnet payloads, persistence, traffic interception or redirection, and use of the device as a pivot or node in broader attacks such as DDoS botnet activity.

Mitigation

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

If no patch is available, restrict access to the device management interface and specifically the /boafrm/formWsc endpoint from untrusted networks. Do not expose the administrative web interface to the internet. Limit management access via firewall or ACLs to trusted internal hosts, place the device behind network segmentation, disable remote administration if not required, and monitor for suspicious requests targeting peerRptPin or /boafrm/formWsc. Given active public disclosure and likely weaponization, replacement of the device may be warranted if exposure cannot be reduced.

Remediation

Patch, then assume compromise.

Upgrade TOTOLINK X2000R to a vendor-fixed firmware version if one becomes available. The provided content only confirms that version 1.0.0-B20230726.1108 is affected and does not identify a patched release. Because the vendor reportedly did not respond to the disclosure, users should monitor TOTOLINK for firmware updates or security advisories and apply any fix immediately once published.
