Exploit100 - bo
When connected to the challenge, the program printed out
"Welcome to CSAW CTF!
Time to break out IDA Demo and see what's going on inside me. :]"
So I opened it up in IDA and looked at the strings.
.rodata:08049300 00000016 C "Welcome to CSAW CTF!\n"
.rodata:08049318 00000044 C "Time to break out IDA Demo and see whats going on inside me. :]\n\n"
.rodata:0804935C 0000001C C "flag{exploitation_is_easy!}"
.rodata:08049378 0000001E C "Unable to set SIGCHLD handler"
.rodata:08049396 00000018 C "Unable to create socket "
.rodata:080493B0 00000022 C "Unable to set socket reuse option"
.rodata:080493D2 00000016 C "Unable to bind socket"
.rodata:080493E8 0000001B C "Unable to listen on socket"

.rodata:08049460 00000023 C "Unable to change current directory"
.rodata:08049483 0000000D C "/dev/urandom"
.eh_frame:0804954B 00000005 C ";*2$\"
