CVE-ovi

Otkrio sam da su automatski alati prilično beskorisni u otkrivanju ranjivosti koje utiču na verziju moodle-a. Možete proveriti za njih na https://snyk.io/vuln/composer:moodle%2Fmoodle

RCE

Potrebno je da imate ulogu menadžera i da možete instalirati dodatke unutar kartice "Administracija sajta"**:**

Ako ste menadžer, možda ćete ipak morati aktivirati ovu opciju. Možete videti kako u moodle PoC za eskalaciju privilegija: https://github.com/HoangKien1020/CVE-2020-14321.

Zatim, možete instalirati sledeći dodatak koji sadrži klasičnu pentest-monkey php rev shell (pre otpremanja morate ga dekompresovati, promeniti IP i port revshella i ponovo kompresovati)

Ili možete koristiti dodatak sa https://github.com/HoangKien1020/Moodle_RCE da biste dobili redovan PHP shell sa parametrom "cmd".

Da biste pristupili pokretanju zlonamernog dodatka, morate pristupiti:

http://domain.com/<moodle_path>/blocks/rce/lang/en/block_rce.php?cmd=id

POST
