CVE-2014-5246The Shenzhen Tenda Technology Tenda A5s router with firmware 3.02.05_CN allows remote attackers to bypass authentication and gain administrator access by setting the admin:language cookie to zh-cn.
CVE-2026-38835Tenda 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.
CVE-2026-31255A command injection vulnerability exists in Tenda AC18 V15.03.05.05_multi. The vulnerability is located in the /goform/SetSambaCfg interface, where improper handling of the guestuser parameter allows attackers to execute arbitrary system commands.
CVE-2026-24115An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Failure to validate the sizes of `gstup` and `gstdwn` before concatenating them into `gstruleQos` may lead to buffer overflow.
CVE-2026-24114An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Failure to validate `pPortMapIndex` may lead to buffer overflows when using `strcpy`.
CVE-2026-24113An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by controlling the value of `nptr`. When this value is passed into the `getMibPrefix` function and concatenated using `sprintf` without proper size validation, it could lead to a buffer overflow vulnerability.
CVE-2026-24112An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by specifying the value of `userInfo`. When `userInfo` is passed into the `addWewifiWhiteUser` function and processed by `sscanf` without size validation, it could lead to a buffer overflow vulnerability.
CVE-2026-24111An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by specifying the value of `userInfo`. When `userInfo` is passed into the `addAuthUser` function and processed by `sscanf` without size validation, it could lead to buffer overflow.
CVE-2026-24110An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may send overly long `addDhcpRules` data. When these rules enter the `addDhcpRule` function and are processed by `ret = sscanf(pRule, " %d\t%[^\t]\t%[^\n\r\t]", &dhcpsIndex, dhcpsIP, dhcpsMac);`, the lack of size validation for the rules could lead to buffer overflows in `dhcpsIndex`, `dhcpsIP`, and `dhcpsMac`.
CVE-2026-24109An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by controlling the value of `picName`. When this value is used in `sprintf` without validating variable sizes, it could lead to a buffer overflow vulnerability.
CVE-2026-24108An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Attackers may exploit the vulnerability by controlling the value of `nptr`. When this value is passed into the `getMibPrefix` function and concatenated using `sprintf` without proper size validation, it could lead to a buffer overflow vulnerability.
CVE-2026-24107An issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Failure to validate the value of `usbPartitionName`, which is directly used in `doSystemCmd`, may lead to critical command injection vulnerabilities.
CVE-2026-24105An issue was discovered in goform/formsetUsbUnload in Tenda AC15V1.0 V15.03.05.18_multi. The value of `v1` was not checked, potentially leading to a command injection vulnerability if injected into doSystemCmd.
CVE-2026-24103A buffer overflow vulnerability was discovered in goform/formSetMacFilterCfg in Tenda AC15V1.0 V15.03.05.18_multi.
CVE-2026-24101An issue was discovered in goform/formSetIptv in Tenda AC15V1.0 V15.03.05.18_multi. When the condition is met, `s1_1` will be passed into sub_B0488, concatenated into `doSystemCmd`. The value of s1_1 is not validated, potentially leading to a command injection vulnerability.
CVE-2025-69766Tenda AX3 firmware v16.03.12.11 contains a stack-based buffer overflow in the formGetIptv function due to improper handling of the citytag stack buffer, which may result in memory corruption and remote code execution.
CVE-2025-69764Tenda AX3 firmware v16.03.12.11 contains a stack-based buffer overflow in the formGetIptv function due to improper handling of the stbpvid stack buffer, which may result in memory corruption and remote code execution.
CVE-2025-69763Tenda AX3 firmware v16.03.12.11 contains a stack overflow in formSetIptv via the vlanId parameter, which can cause memory corruption and enable remote code execution.
CVE-2025-69762Tenda AX3 firmware v16.03.12.11 contains a stack overflow in formSetIptv via the list parameter, which can cause memory corruption and enable remote code execution.
CVE-2025-67073A Buffer overflow vulnerability in function fromAdvSetMacMtuWan of bin httpd in Tenda AC10V4.0 V16.03.10.20 allows remote attackers to cause denial of service and possibly code execution by sending a post request with a crafted payload (field `serviceName`) to /goform/AdvSetMacMtuWan.
CVE-2025-63666Tenda AC15 v15.03.05.18_multi) issues an authentication cookie that exposes the account password hash to the client and uses a short, low-entropy suffix as the session identifier. An attacker with network access or the ability to run JS in a victim browser can steal the cookie and replay it to access protected resources.
CVE-2025-57085Tenda W30E V16.01.0.19 (5037) was discovered to contain a stack overflow in the v17 parameter in the UploadCfg function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.
CVE-2025-55613Tenda O3V2 1.0.0.12(3880) is vulnerable to Buffer Overflow in the fromSafeSetMacFilter function via the mac parameter.
CVE-2025-52221Tenda AC6 15.03.05.16_multi is vulnerable to Buffer Overflow in the formSetCfm function via the funcname, funcpara1, and funcpara2 parameters.
CVE-2025-45779Tenda AC10 V1.0re_V15.03.06.46 is vulnerable to Buffer Overflow in the formSetPPTPUserList handler via the list POST parameter.
