Executive Summary

CVE-2025-11099 is a command injection vulnerability in the D-Link DIR-823X router (version 250416). It exists in the function uci_del within the file /goform/delete_prohibiting. The vulnerability occurs because the delvalue argument is not properly validated or sanitized, allowing an attacker to inject and execute arbitrary commands on the device remotely without needing local access. This flaw corresponds to CWE-77, meaning that external input is used unsafely to construct commands, leading to command injection. [1, 2]

Impact Analysis

This vulnerability can impact you by allowing remote attackers to execute arbitrary commands on your D-Link DIR-823X router, potentially compromising the device's confidentiality, integrity, and availability. Attackers could take control of the device, disrupt its operation, or use it as a foothold for further attacks. Since the exploit is publicly available and can be executed remotely without user interaction, the risk of exploitation is significant. [1]

Detection Guidance

There are no specific detection commands or network/system detection methods provided in the available resources for CVE-2025-11099. The vulnerability involves command injection via the 'delvalue' parameter in the /goform/delete_prohibiting handler of the D-Link DIR-823X router firmware version 250416. Detection would likely require monitoring for unusual or unauthorized commands executed on the device or inspecting HTTP requests targeting the /goform/delete_prohibiting endpoint with suspicious 'delvalue' parameters. However, no explicit detection commands or tools are mentioned. [1, 2]

Mitigation Strategies

No known countermeasures or mitigations have been identified for this vulnerability. The recommended immediate step is to replace the affected D-Link DIR-823X router with an alternative device. Since the vulnerability allows remote command injection and has a publicly available exploit, discontinuing use of the vulnerable firmware version 250416 is advised to prevent exploitation. [1]
