A flaw has been found in Tenda AC5 15.03.06.47. This vulnerability affects the function formQuickIndex of the file /goform/QuickIndex of the component POST Request Handler. This manipulation of the argument PPPOEPassword causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been published and may be used.
AnalysisAI
Remote attackers with low-level credentials can execute arbitrary code on Tenda AC5 wireless routers running firmware version 15.03.06.47 by exploiting a stack-based buffer overflow in the formQuickIndex function via a crafted PPPOEPassword parameter in POST requests to /goform/QuickIndex. Publicly available exploit code exists, including detailed proof-of-concept documentation published on Notion, elevating immediate risk for devices exposed to authenticated network users. …

Vulnerability AssessmentAI
| Exploitation | Requires authenticated access to Tenda AC5 router (version 15.03.06.47). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is elevated due to convergence of multiple threat indicators. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained low-privilege credentials (through default passwords, credential stuffing, or prior compromise of network devices) authenticates to the Tenda AC5 web management interface. They craft a malicious POST request to /goform/QuickIndex containing an oversized PPPOEPassword parameter designed to overflow the stack buffer and redirect execution to attacker-controlled shellcode. … |
| Remediation | No vendor-released patch identified at time of analysis based on available reference data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and inventory all Tenda AC5 routers running firmware 15.03.06.47 in your environment; restrict administrative access to these devices to trusted personnel only. …
