Summary

CVE-2026-0581 is a medium-severity Injection (CWE-74) vulnerability in Tenda Ac1206 Firmware. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-0581 is a command injection vulnerability affecting the Tenda AC1206 router running firmware version 15.03.06.23. The flaw resides in the formBehaviorManager function within the /goform/BehaviorManager file of the httpd component. An attacker can exploit it by manipulating the arguments modulename, option, data, or switch to inject and execute arbitrary commands.

The vulnerability enables remote exploitation over the network with low complexity and requires low privileges, such as those of an authenticated user (PR:L). Successful attacks can result in limited impacts on confidentiality, integrity, and availability, as reflected in its CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). It maps to CWE-74 (Improper Neutralization of Special Elements) and CWE-77 (Command Injection).

Advisories on VulDB (ctiid.339473, id.339473, submit.731193) and a GitHub repository document the issue, including a publicly disclosed proof-of-concept exploit. The vendor's site at tenda.com.cn is referenced, but no specific patches or mitigation steps are detailed in the available information.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.
