CVE-2025-60674: n/a
A stack buffer overflow vulnerability exists in the D-Link DIR-878A1 router firmware FW101B04.bin in the rc binary's USB storage handling module. The vulnerability 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. An attacker with physical access or control over a USB device can exploit this vulnerability to potentially execute arbitrary code on the device.
AI Analysis
Technical Summary
CVE-2025-60674 describes a stack buffer overflow in the D-Link DIR-878A1 router firmware (FW101B04.bin) in the rc binary's USB storage handling code. The vulnerability occurs due to improper handling of the USB device's "Serial Number" field, where sscanf copies data into a 64-byte stack buffer but fgets reads up to 127 bytes, causing a stack overflow. An attacker with physical access or control over a USB device connected to the router can exploit this to potentially execute arbitrary code on the device. No patch or remediation information is currently available.
Potential Impact
Successful exploitation can lead to arbitrary code execution on the affected router, compromising confidentiality, integrity, and availability. The attacker must have physical access or control over a USB device connected to the router. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict physical access to the router and avoid connecting untrusted USB devices to mitigate risk.
