A command injection vulnerability has been identified in Tenda AC10 V1.0 V15.03.06.23. This vulnerability allows attackers to execute arbitrary commands via the formexeCommand function, where the str variable receives the cmdinput parameter from a POST request. The cmd_buf variable is directly utilized in the doSystemCmd function, leading to a critical security risk.
With a CVSS score of 9.8, this vulnerability is classified as critical. The severity is underscored by the potential for high confidentiality, integrity, and availability impacts, making it vital for organizations using affected systems to act swiftly.
Risk to organizations includes unauthorized access to sensitive data and system compromise. Attackers may leverage this vulnerability to execute arbitrary commands, posing a severe threat to the integrity and availability of network resources.
Organizations should prioritize patching immediately to protect against potential exploitation.
Vulnerability Details
The official description of this vulnerability states that Tenda AC10 V1.0 V15.03.06.23 has a command injection vulnerability located in the formexeCommand function. The str variable receives the cmdinput parameter from a POST request and is later assigned to the cmd_buf variable, which is directly used in the doSystemCmd function, allowing for arbitrary command execution.
This vulnerability falls under the CWE classifications CWE-77 (Command Injection) and CWE-94 (Code Injection).
The CVSS score of 9.8 signifies a critical severity level, indicating an urgent need for remediation.
Affected products include Tenda AC10 firmware version 15.03.06.23, with the vulnerability being published on February 20, 2025.
Technical Analysis
The root cause of this vulnerability is improper handling of user input in the formexeCommand function. The attack vector is network-based, and the attack complexity is low, as no privileges or user interaction are required for exploitation.
The vulnerability requires no privileges to exploit, and user interaction is not necessary. The potential impacts on confidentiality, integrity, and availability are all rated as high.
