used.

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents path traversal exploitation by validating inputs to the R7WebsSecurityHandlerfunction in the HTTP Handler, blocking malicious path manipulations.

prevent

Requires timely flaw remediation such as firmware patching for Tenda i9 1.0.0.5(2204), eliminating the root cause of the vulnerability.

prevent

Boundary protection mechanisms like web application firewalls can inspect and block path traversal attempts in unauthenticated remote HTTP requests to the affected component.

Security SummaryAI

CVE-2026-7036 is a path traversal vulnerability (CWE-22) in Tenda i9 firmware version 1.0.0.5(2204). It affects the R7WebsSecurityHandlerfunction within the HTTP Handler component. Published on 2026-04-26, the issue has a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), reflecting its network-based exploitability without authentication or user interaction.

Remote attackers can exploit this vulnerability over the network with no privileges required. By manipulating inputs to the HTTP Handler, they can traverse paths to access unintended files, achieving limited impacts on confidentiality (C:L), integrity (I:L), and availability (A:L).

Advisories and details are documented on VulDB (https://vuldb.com/vuln/359616, https://vuldb.com/vuln/359616/cti, https://vuldb.com/submit/798479), a GitHub repository (https://github.com/Litengzheng/vuldb_new/blob/main/M3/vul_80/README.md), and the Tenda vendor site (https://www.tenda.com.cn/). Security practitioners should consult these for any recommended patches or mitigations.

The exploit is publicly available, raising concerns for potential active use against unpatched Tenda i9 devices.
