CVE-2026-102816

Unauthenticated Wireless Regulatory Region Configuration in TP-Link RE305

An authorization vulnerability exists in the country or region configuration interface of TP-Link RE305 V3. An unauthenticated attacker on the same local network may modify the wireless regulatory region and force the device to reapply its wireless configuration.  Successful exploitation may cause wireless connection interruptions, unavailable channels, client disconnections, or wireless service instability, and may cause the device to apply parameters intended for a different regulatory region.

Administrator Password Reset Through the Verification-Code Interface in TP-Link RE305

An authentication flaw exists in the password-recovery functionality of TP-Link RE305 V3. The verification-code interface allows an unauthenticated attacker on the same local network to trigger generation of an administrator password-reset verification code. Because the interface lacks an effective attempt counter or lockout mechanism and uses a predictable verification-code generation process, an attacker may obtain or brute-force the code and reset the administrator password.  Successful exploitation may allow an unauthenticated attacker on the local network to reset the administrator password and subsequently access privileged device-management functions.

Hardcoded AES-128 Key and Fixed IV in Configuration Backup Encryption in TP-Link RE305 and Archer C7

A hard-coded cryptographic key vulnerability exists in the user-configuration backup mechanism of TP-Link RE305 V3 and Archer C7 V5. A fixed AES-128 key and initialization vector are embedded in the firmware configuration-management component. An attacker who obtains an affected configuration backup file may extract the cryptographic material from the firmware and use it to decrypt the backup.  Successful exploitation may disclose sensitive configuration information contained in a backup file, including administrator passwords and Wi-Fi credentials.

Command Injection in tmpServer Allows Local Privilege Escalation in TP-Link RE305

An operating-system command injection vulnerability exists in the tmpServer service of TP-Link RE305 V3. The service runs with root privileges and listens on the local loopback interface. A local attacker with access to a low-privileged process on the device may submit a crafted request to the TDDPv1 service and execute operating-system commands with root privileges. Successful exploitation may allow a local attacker with low privileges to obtain root privileges and execute arbitrary operating-system commands on the affected device.

Improper Authentication in TP-Link TDDP v2 Allows Root Command Execution in TP-Link RE305

An authentication weakness exists in the TP-Link TDDP v2 service of TP-Link RE305 V3. TDDP v2 uses a fixed and derivable cryptographic key, which may allow an unauthenticated attacker on the same local network to forge protocol packets and access privileged TDDP operations, including functionality that can lead to operating-system command execution when the TDDP service is running and accessible. Successful exploitation may allow an unauthenticated attacker on the same local area network to execute arbitrary system commands with root privileges.

Authentication Logic Vulnerability on Multiple TP-Link Range Extenders

An authentication logic vulnerability in multiple TP-Link range extenders allows an unauthenticated attacker on an adjacent network to manipulate a login parameter and reset the administrator password due to insufficient validation. Successful exploitation allows an attacker to obtain full administrative control of the affected device, potentially impacting on confidentiality, integrity, and availability.
