Summary

CVE-2026-6024 is a high-severity Path Traversal (CWE-22) vulnerability in Tenda I6 Firmware. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 49.3th percentile by exploit likelihood (below the median); 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-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Remediates the specific path traversal vulnerability in the R7WebsSecurityHandler function of the HTTP Handler by identifying, reporting, and applying vendor firmware patches.

SI-10 Information Input Validation good match

prevent

Validates and sanitizes inputs to the HTTP Handler to block path traversal manipulations such as '../' sequences.

AC-3 Access Enforcement partial match

prevent

Enforces approved access authorizations in the HTTP Handler to restrict unauthorized traversal to files and directories outside intended paths.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

attack.mitre.org →

T1083 File and Directory Discovery Discovery

Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

attack.mitre.org →

Why these techniques?

Path traversal in public-facing HTTP handler on router directly enables T1190 (exploit public-facing app) for initial access and facilitates T1005/T1083 (data/file discovery from local system via arbitrary file access).

NVD Description

A vulnerability was determined in Tenda i6 1.0.0.7(2204). Affected by this issue is the function R7WebsSecurityHandlerfunction of the component HTTP Handler. This manipulation causes path traversal. It is possible to initiate the attack remotely. The exploit has been publicly disclosed…

and may be utilized.

Deeper analysisAI

CVE-2026-6024 is a path traversal vulnerability (CWE-22) affecting Tenda i6 routers running firmware version 1.0.0.7(2204). The flaw resides in the R7WebsSecurityHandlerfunction of the HTTP Handler component, enabling manipulation that allows attackers to traverse directory paths.

The vulnerability can be exploited remotely by unauthenticated attackers with network access and no requirement for user interaction, as reflected in its CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Exploitation grants limited impacts on confidentiality, integrity, and availability, and the proof-of-concept exploit has been publicly disclosed, making it readily utilizable.

Advisories published on 2026-04-10 detail the issue on VulDB (https://vuldb.com/vuln/356600) and related CTI pages, with a disclosure repository on GitHub (https://github.com/Litengzheng/vuldb_new/blob/main/M3/vul_84/README.md). Practitioners should consult the vendor site (https://www.tenda.com.cn/) for patch information or mitigation steps.
