CVE-2025-10634 is a command injection vulnerability in D-Link DIR-823X routers running firmware versions 240126, 240802, and 250416. The flaw affects the sub_412E7C function in the /usr/sbin/goahead file, part of the Environment Variable Handler component. It arises from improper handling of the terminal_addr, server_ip, or server_port arguments, enabling injected commands. Published on 2025-09-18T02:15:40.273, the vulnerability carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and maps to CWEs-74 and CWE-77.
The vulnerability is remotely exploitable over the network with low attack complexity and no user interaction required. Exploitation demands low privileges (PR:L), such as those of an authenticated user. Attackers can achieve limited impacts, including low-level disclosure of information, modification of data, and denial of service through command injection.
References point to a GitHub repository with exploit details, a Baidu share likely containing the exploit, and multiple VulDB entries. No specific mitigation steps or patches are described in the available information; practitioners should review vendor guidance and the linked advisories for remediation options.
An exploit is publicly available, heightening the potential for real-world abuse against unpatched devices.

Mitigating Controls
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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing in development catches injection vulnerabilities before release.
Monitoring activities can identify active injection attacks after they occur.
Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
