| タイトル | MOVIE TICKET BOOKING SYSTEM Buffer Overflow in Password Authentication Function v1.0 Buffer Overflow |
|---|
| 説明 | A stack-based buffer overflow vulnerability exists in the `changeprize` function of the `PRODUCT_MANAGEMENT_SYSTEM`. The vulnerability is caused by the use of `scanf("%s", &pass)` to read user input into a fixed-size buffer `pass[10]`, which can only safely hold 9 characters plus a null terminator. Since `scanf("%s")` does not enforce any length restriction, input of 10 or more bytes will overflow the buffer.
This overflow can lead to memory corruption, overwriting the adjacent hard-coded password buffer `pak[10]`, and potentially tampering with the function’s return address depending on the stack layout. This flaw can be exploited to cause a denial of service (DoS) or execute arbitrary code.
