Multiple buffer overflow vulnerabilities exist in the HTTPd server in Asus asuswrt version <=3.0.0.4.376.X. All have been fixed in version 3.0.0.4.378, but this vulnerability was not previously disclosed. Some end-of-life routers have this version as the newest and thus are vulnerable at this time. This vulnerability allows for RCE with administrator rights when the administrator visits several pages.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
