Tiandy Easy7 Integrated Management Platform OS Command Injection Vulnerability

A critical vulnerability, CVE-2026-7698, has been identified in Tiandy Easy7 Integrated Management Platform version 7.17.0. This vulnerability resides within the /Easy7/rest/systemInfo/updateDbBackupInfo file, specifically related to the week argument. Successful exploitation allows for arbitrary OS command injection. This vulnerability is remotely exploitable, meaning an attacker can trigger it over the network without needing local access. Publicly available exploit code exists, increasing the likelihood of exploitation. The vendor was notified but has not responded. Defenders should take immediate action to mitigate this risk.

Attack Chain

1. An attacker identifies a vulnerable Tiandy Easy7 Integrated Management Platform running version 7.17.0.
2. The attacker crafts a malicious HTTP request targeting the /Easy7/rest/systemInfo/updateDbBackupInfo endpoint.
3. The crafted request includes a payload within the week argument designed to inject OS commands.
4. The vulnerable application fails to properly sanitize or validate the week argument.
5. The application executes the injected OS command with the privileges of the web server.
6. The attacker gains arbitrary code execution on the server.
7. The attacker can then perform further actions such as installing malware, exfiltrating data, or pivoting to other systems on the network.

Impact

Successful exploitation of CVE-2026-7698 allows an attacker to execute arbitrary commands on the affected system. This could lead to complete system compromise, data breaches, denial of service, or further lateral movement within the network. Given the publicly available exploit, organizations using Tiandy Easy7 Integrated Management Platform 7.17.0 are at immediate risk.

Recommendation

• Apply available patches from Tiandy if they become available.
• Monitor web server logs for requests to /Easy7/rest/systemInfo/updateDbBackupInfo containing suspicious characters or command injection attempts. Deploy the Sigma rule Detect Suspicious Requests to updateDbBackupInfo to your SIEM.
• Implement input validation and sanitization on the week argument within the /Easy7/rest/systemInfo/updateDbBackupInfo endpoint.
• Monitor process creation events for unusual processes spawned by the web server, using the Sigma rule Detect OS Command Injection via Web Request.
• Review and restrict network access to the Tiandy Easy7 Integrated Management Platform to only authorized users and systems.
