W30e Firmware

Tenda W30E V2.0 V16.01.0.21 was found to contain a command injection vulnerability in the formSetUSBPartitionUmount function via the usbPartitionName parameter. This vulnerability allows attackers to execute arbitrary commands via a crafted request.Show less

Tenda W30E V2.0 V16.01.0.21 was found to contain a command injection vulnerability in the do_ping_action function via the hostName parameter. This vulnerability allows attackers to execute arbitrary commands via a crafted request.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) allow account passwords to be changed through the maintenance interface without requiring verification of the existing password. This enables unauthorized password changes when access to the affected endpoint is obtained.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) fail to include the X-Content-Type-Options: nosniff response header on web management interfaces. As a result, browsers that perform MIME sniffing may incorrectly interpret attacker-influenced responses as executable script.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) serve sensitive administrative content without appropriate cache-control directives. As a result, browsers may store credential-bearing responses locally, exposing them to subsequent unauthorized access.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) do not enforce rate limiting or account lockout mechanisms on authentication endpoints. This allows attackers to perform unrestricted brute-force attempts against administrative credentials.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) implement an insecure Cross-Origin Resource Sharing (CORS) policy on authenticated administrative endpoints. The device sets Access-Control-Allow-Origin: * in combination with Access-Control-Allow-Credentials: true, allowing attacker-controlled origins to issue credentialed cross-origin requests.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) contain a stored cross-site scripting vulnerability in the user creation functionality. Insufficient input validation allows attacker-controlled script content to be stored and later executed when administrative users access the affected management pages.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) lack cross-site request forgery (CSRF) protections on administrative endpoints, including those used to change administrator account credentials. As a result, an attacker can craft malicious requests that, when triggered by an authenticated user’s browser, modify administrative passwords and other configuration settings.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) display stored user account passwords in plaintext within the administrative web interface. Any user with access to the affected management pages can directly view credentials.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) disclose sensitive account credentials in cleartext within HTTP responses generated by the maintenance interface. Because the management interface is accessible over unencrypted HTTP by default, credentials may be exposed to network-based interception.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) ship with a predefined default password for a built-in authentication account that is not required to be changed during initial configuration. An attacker can leverage these default credentials to gain authenticated access to the management interface.Show less

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) contain an authorization flaw in the user management API that allows a low-privileged authenticated user to change the administrator account password. By sending a crafted request directly to the backend endpoint, an attacker can bypass role-based restrictions enforced by the web interface and obtain full administrative privileges.Show less

Tenda W30E V16.01.0.19 (5037) was discovered to contain a stack overflow in the String parameter in the formDeleteMeshNode function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.Show less

Tenda W30E V16.01.0.19 (5037) was discovered to contain a stack overflow in the countryCode parameter in the werlessAdvancedSet function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.Show less

A vulnerability classified as critical has been found in Tenda W30E 1.0/1.0.1.25. Affected is the function fromWizardHandle of the file /goform/WizardHandle. The manipulation of the argument PPW leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-261990 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.Show less
