Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly mitigates command injection by requiring validation of untrusted inputs like the bandstr parameter in the /bin/boa web component.

prevent

Addresses the root cause by requiring timely identification, reporting, and correction of the specific command injection flaw in TOTOLINK A3002R firmware.

detect

Enables periodic and event-driven vulnerability scanning to identify the CVE-2025-25579 command injection vulnerability in the affected router firmware.

MITRE ATT&CK Enterprise TechniquesAI

T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

The vulnerability is a remote unauthenticated OS command injection via the web interface (boa) on a network device (router), enabling exploitation of a public-facing application (T1190) and command/script execution using the network device CLI/interpreter (T1059.008).

NVD Description

TOTOLINK A3002R V4.0.0-B20230531.1404 is vulnerable to Command Injection in /bin/boa via bandstr.

Deeper analysisAI

CVE-2025-25579 is a command injection vulnerability (CWE-78) affecting the TOTOLINK A3002R router running firmware version V4.0.0-B20230531.1404. The flaw resides in the /bin/boa component and is triggered via the "bandstr" parameter, allowing attackers to inject operating system commands. It has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its potential for complete system compromise.

Any unauthenticated attacker with network access to the affected device can exploit this vulnerability without user interaction or privileges. Successful exploitation enables remote command execution, granting full control over the router, including data exfiltration, modification of configurations, or disruption of services.

Proof-of-concept exploits are available in public repositories, such as https://gist.github.com/regainer27/0abf6f56eae3fa2826d2551e22c2ace3 and https://github.com/regainer27/totolink_A3002R_remote_command_exec, demonstrating remote command execution capabilities. No official vendor advisories or patches are detailed in the available references.
