Executive Summary

This vulnerability is a command injection flaw in Tenda CH22 version 1.0.0.1. It exists in the function formeditFileName within the file /goform/editFileName. The issue arises from improper handling of the editNameMit argument, allowing attackers to inject malicious commands. The exploit is remotely accessible and has been publicly disclosed.

Detection Guidance

This vulnerability involves command injection in Tenda CH22 via the /goform/editFileName endpoint. To detect it, check network traffic for unusual requests to this path with parameters like editNameMit. Inspect logs for suspicious command execution attempts or unexpected system behavior.

Impact Analysis

An attacker could exploit this to execute arbitrary commands on the affected device. This may lead to unauthorized access, data theft, or device compromise. Since the attack is remote, users with vulnerable devices connected to a network are at risk.

Compliance Impact

This vulnerability involves command injection in Tenda CH22 firmware, allowing remote attackers to execute arbitrary commands. Such flaws can lead to unauthorized data access, modification, or exfiltration, which may violate GDPR (data protection) and HIPAA (health data privacy) requirements for secure systems and breach notifications.

Mitigation Strategies

Immediately update the Tenda CH22 firmware to the latest version if an update is available. Disable remote access to the device if not required. Monitor network traffic for unusual activity involving the /goform/editFileName endpoint. Consider isolating the device from critical network segments until patched.
