Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-15257 is a command injection vulnerability affecting the Edimax BR-6208AC router running firmware versions 1.02 and 1.03, specifically the V2 model. The flaw resides in the formRoute function within the /gogorm/formRoute endpoint of the Web-based Configuration Interface. By manipulating the strIp, strMask, or strGateway arguments, an attacker can inject arbitrary commands, as classified under CWE-74 and CWE-77. The vulnerability carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) and was published on 2025-12-30.

The vulnerability enables remote exploitation without authentication or user interaction, allowing unauthenticated attackers anywhere on the network to execute arbitrary commands on the device. Successful exploitation could result in limited impacts, including low-level confidentiality, integrity, and availability compromises, such as data leakage, configuration tampering, or denial of service.

Edimax has confirmed the issue but states that the BR-6208AC V2 has reached end-of-life (EOL) status, meaning it is unsupported, unmaintained, and unavailable for purchase. No firmware updates or patches will be provided, and users are advised to upgrade to newer models. This vulnerability exclusively affects these discontinued products.

An exploit for CVE-2025-15257 has been publicly released and may be leveraged in attacks targeting exposed EOL devices.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.
