A vulnerability, which was classified as critical, has been found in TP-Link TL-WR940N V4. Affected by this issue is some unknown functionality of the file /userRpm/WanSlaacCfgRpm.htm. The manipulation of the argument dnsserver1 leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
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.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
