CVE-2026-5844: OS Command Injection in D-Link DIR-882
CVE-2026-5844 is a high-severity OS command injection vulnerability in the D-Link DIR-882 router version 1. 01B02. The issue exists in the sprintf function within the prog. cgi file, specifically in the HNAP1 SetNetworkSettings Handler, where manipulation of the IPAddress argument allows remote attackers to execute arbitrary OS commands. The vulnerability affects an unsupported product version, and while the exploit code has been publicly disclosed, no known exploits in the wild have been reported. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
This vulnerability involves an OS command injection in the D-Link DIR-882 router firmware version 1.01B02. The flaw is located in the sprintf function of the prog.cgi file, within the HNAP1 SetNetworkSettings Handler. By manipulating the IPAddress parameter, an attacker with high privileges can remotely execute arbitrary operating system commands. The vulnerability has a CVSS 4.0 base score of 8.6, indicating high severity. The affected product is no longer supported by D-Link, and no official fix or patch has been published. Exploit code has been made public, but no confirmed exploitation in the wild is documented.
Potential Impact
Successful exploitation of this vulnerability allows a remote attacker with high privileges to execute arbitrary OS commands on the affected device, potentially leading to full compromise of the router. This could impact network security and device integrity. However, the affected product version is no longer supported, and no active exploitation has been reported.
Mitigation Recommendations
No official patch or remediation is currently available from the vendor, and the product is no longer supported. Users should consider replacing the affected device with a supported model to mitigate risk. Until then, restricting remote access to the device's management interface and disabling HNAP1 services, if possible, may reduce exposure. Monitor vendor advisories for any updates.
