A vulnerability, which was classified as critical, was found in TOTOLINK AC1200 T8 and AC1200 T10 4.1.5cu.861_B20230220/4.1.8cu.5207. This affects the function setParentalRules of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument desc/week/sTime/eTime leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Other parameters might be affected as well. The vendor was contacted early about this disclosure but did not respond in any way.
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.
