Detailsinfo

A vulnerability was found in TOTOLINK A950RG 5.9c.4592_B20191022_ALL. It has been classified as critical. Affected is the function CsteSystem of the file system.so of the component HTTP Handler. The manipulation of the argument ipDoamin with an unknown input leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A command injection vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the `system.so` binary. The `setDiagnosisCfg` function retrieves the `ipDoamin` parameter from user input via `websGetVar` and concatenates it directly into a `ping` system command executed via `CsteSystem()` without any sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.

This vulnerability is traded as CVE-2025-60702 since 09/26/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 11/14/2025). This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
