CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-29041 is a critical-severity OS Command Injection (CWE-78) vulnerability in Dlink Dir-823X Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 32% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-29041 is a command injection vulnerability (CWE-78) in the D-Link DIR-823x router running firmware version 240802. The flaw resides in the handling of the target_addr key value passed to function 0x41710c, which fails to sanitize input and permits execution of arbitrary operating-system commands.
Unauthenticated attackers with network access can supply a malicious target_addr parameter to trigger the injection, resulting in remote code execution with full control over the device and no user interaction required. The issue carries a CVSS 3.1 base score of 9.8, reflecting its critical severity and ease of exploitation.
D-Link has published a security bulletin addressing the router, while public proof-of-concept code demonstrating the diag_nslookup command-injection vector is available in GitHub repositories. The associated EPSS score reached a peak of 0.0879 on 2026-06-04 before receding to its current value of 0.0476.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
