Summary
An unauthenticated command injection vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin. The vulnerability occurs in the 'SetDMZSettings' functionality, where the 'IPAddress' parameter in prog.cgi is stored in NVRAM and later used by librcm.so to construct iptables commands executed via twsystem(). An attacker can exploit this vulnerability remotely without authentication by sending a specially crafted HTTP request, leading to arbitrary command execution on the device.
Risk Assessment
The risk for the organization includes full compromise of the router, potentially allowing the attacker to intercept network traffic, modify configurations, or use the device as an entry point into the internal network.
Recommendation
Immediately update the D-Link DIR-878A1 router firmware to the latest version if a patch is available. If no update is available, disable the DMZ feature or restrict access to the management interface to trusted IP addresses only.
Other vulnerabilities in D-Link DIR-878A1
See all- CVE-2025-60676Medium
An unauthenticated command injection vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin. The vulnerability occurs in the 'SetNetworkSettings' functionality of prog.cgi, where the 'IPAddress' and 'SubnetMask' parameters are directly concatenated into shell commands executed via system().
- CVE-2025-60674Medium
A stack buffer overflow vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin in the USB storage handling module. The issue occurs when the "Serial Number" field from a USB device is read via sscanf into a 64-byte stack buffer, while fgets reads up to 127 bytes, causing a stack overflow.
- CVE-2025-60672Medium
An unauthenticated command injection vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin. The issue is in the 'SetDynamicDNSSettings' functionality, where 'ServerAddress' and 'Hostname' parameters are stored in NVRAM and later used to construct system commands executed via twsystem(). An attacker can exploit this remotely without authentication by sending a crafted HTTP request, leading to arbitrary command execution on the device.
