HIGH 8.8

DescriptionCVE.org

A vulnerability was found in Tenda AC500 2.0.1.9(1307). It has been declared as critical. Affected by this vulnerability is the function formSetAPCfg of the file /goform/setWtpData. The manipulation of the argument radio_2g_1 leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

A critical remote code execution vulnerability affects Tenda AC500 wireless access points (version 2.0.1.9 and earlier), allowing unauthenticated attackers to execute arbitrary code and potentially compromise network infrastructure. Organizations using this device model face immediate risk of network breach, data exfiltration, and lateral movement into connected systems. With public exploits available and no patch released, this requires urgent remediation to prevent active exploitation.

Business Impact: Severe

Compensating Controls

Implement WAF rules to block POST requests to /goform/setWtpData endpoint; disable the setWtpData function if not operationally required; segment access points onto isolated network VLANs with strict ingress/egress filtering; disable remote administration interfaces and enforce local-only management; deploy network-based IDS/IPS signatures detecting buffer overflow payloads to this endpoint; restrict administrative access to whitelist of known management workstations only.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
