Technical ContextAI · show details

This vulnerability (CWE-78: OS Command Injection) exists in the NTPSyncWithHost component. TOTOLINK X6000R v9.4.0cu.1498_B20250826 contains an OS command injection vulnerability in the NTPSyncWithHost handler of the /usr/sbin/shttpd executable. The host_time parameter is retrieved via sub_40C404 and passed to a date -s shell command through CsteSystem. While the first two tokens of the input are validated, the remainder of the string is not sanitized, allowing authenticated attackers to execute arbitrary shell commands via shell metacharacters.

DescriptionCVE.org

TOTOLINK X6000R v9.4.0cu.1498_B20250826 contains an OS command injection vulnerability in the NTPSyncWithHost handler of the /usr/sbin/shttpd executable. The host_time parameter is retrieved via sub_40C404 and passed to a date -s shell command through CsteSystem. While the first two tokens of the input are validated, the remainder of the string is not sanitized, allowing authenticated attackers to execute arbitrary shell commands via shell metacharacters.

Executive ViewAI

Why It Matters

A critical remote code execution vulnerability (CVE-2025-70328) affects X6000R devices running firmware versions up to 9.4.0cu.1498_b20250826, allowing attackers to execute arbitrary operating system commands without authentication. With active public exploits available and no vendor patch currently released, this poses an immediate risk to any organization using affected X6000R hardware in production environments.

Business Impact: High
Compensating Controls
  1. Implement network segmentation to restrict X6000R device access to trusted administrative users only. 2) Deploy WAF/IDS rules to detect and block OS command injection payloads (metacharacters: |, ;, &, $, `, newlines). 3) Disable unnecessary services or features on affected devices if documentation permits. 4) Enable enhanced logging and monitoring for suspicious command patterns. 5) Require multi-factor authentication for all X6000R administrative access. 6) Consider temporary device shutdown if devices are non-critical until patch availability confirmed.
