Deeper analysis
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.
