AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a local stack-based buffer overflow in two binaries (infostat.cgi and cstecgi.cgi) of certain ToToLink routers. These programs improperly parse the /proc/net/arp file using sscanf() with %s format specifiers into fixed-size stack buffers without checking the length of the input. One function writes user-controlled data into a single-byte buffer, and another writes into adjacent small arrays without bounds checking. This can cause memory corruption.
How can this vulnerability impact me? :
An attacker who can control the contents of /proc/net/arp on the affected router can exploit this vulnerability to cause memory corruption. This can lead to denial of service (crashing the device) or potentially allow the attacker to execute arbitrary code on the device.
