The payload php://filter/read=convert.base64-encode/resource=/root/.aws/credentials exploits Local File Inclusion (LFI) to bypass PHP filters and read sensitive AWS credentials, typically located outside the web root [1]. This attack succeeds due to improper user input validation, allowing attackers to access and base64-encode the credentials file for exfiltration [1].

• %3A = :
• %2F = /
• %3D = =

Sanitize Inputs

: Never pass user-controllable input directly into functions like include() , require() , or file_get_contents() . %3A = : %2F = / %3D = =
