Summary
CVE-2025-9006 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda Ch22 Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 44.5% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires validation of inputs to the formdelFileName function in /goform/delFileName to prevent buffer overflow from malformed filenames.
Implements memory protections like stack canaries or DEP to block exploitation of the buffer overflow for arbitrary code execution.
Mandates timely remediation of the identified buffer overflow flaw in Tenda CH22 firmware version 1.0.0.1 via patching.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in public web management interface (/goform/delFileName) directly enables remote exploitation of a network device.

Deeper analysisAI
CVE-2025-9006 is a buffer overflow vulnerability in Tenda CH22 firmware version 1.0.0.1. The flaw affects the formdelFileName function within the /goform/delFileName file, allowing remote manipulation that triggers the overflow. It is classified under CWE-119 and CWE-120, with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
An attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary code execution or system takeover on the affected device.
Advisories and details are documented on VulDB (ctiid.320035, id.320035, submit.628845) and a proof-of-concept exploit is publicly disclosed in a GitHub issue (moweizhang1994/cve/issues/2). The Tenda manufacturer's site (tenda.com.cn) is referenced, but no specific patches or mitigation steps are detailed in the provided information.
