DescriptionCVE.org

A weakness has been identified in UTT 进取 521G 3.1.1-190816. Affected by this issue is the function doSystem of the file /goform/setSysAdm. Executing a manipulation of the argument passwd1 can lead to command injection. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.

Executive ViewAI

Why It Matters

A command injection vulnerability (CVE-2026-2182) affecting 521G firmware versions up to 3.1.1-190816 poses a high risk to organizations using this equipment, as attackers could execute arbitrary commands with a 7.2 CVSS severity rating. With public exploits available and no vendor patch currently released, immediate mitigation actions are required to prevent potential unauthorized access or system compromise.

Business Impact: High

Compensating Controls

Implement network segmentation to restrict access to affected 521G devices; deploy Web Application Firewall (WAF) rules to detect and block command injection payloads; disable unnecessary administrative interfaces and remote management features; enforce strong authentication and IP whitelisting for device access; implement continuous network monitoring for suspicious command execution patterns; establish an incident response plan specific to this vulnerability pending patch availability.
