Re305 V3

A hard-coded cryptographic key vulnerability exists in TP-Link RE305 V3 and Archer C7 V5. The same RSA-1024 private key is stored within firmware configuration files and reused across devices. An attacker who obtains the private key and captures an HTTP Web UI login session may use the key to decrypt the administrator password.  Successful exploitation may disclose the administrator password captured from an HTTP login session and compromise session confidentiality.

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.

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.

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.

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.
