| 描述 | filter_arp_put_file_cgi reads raw upload chunks into a stack buffer and then passes them to fprintf(stderr, "%s") and fputs(). A NUL-free 1024-byte chunk makes both string APIs walk past the received data into adjacent stack memory, leaking bytes into logs and the imported /tmp/filter_arp_file contents. An authenticated attacker who posts a multipart file named put_file can force this over-read on /router/filter_arp_put_file.cgi without any terminator at the end of the received chunk. |
