Specifically, this payload attempts to bypass security filters by encoding the contents of a sensitive system file ( /root/.aws/credentials ) into before displaying it on the screen. If successful, an attacker could decode that string to steal AWS access keys and take over a cloud environment.

function decodeCredentials($encodedCredentials) $decodedCredentials = base64_decode($encodedCredentials); $credentials = explode(':', $decodedCredentials); return [ 'accessKeyId' => $credentials[0], 'secretAccessKey' => $credentials[1], ]; $credentials = explode(':'

Attackers often double URL-encode this payload ( %252F for / ) to bypass security filters (WAF) that scan for malicious strings. return [ 'accessKeyId' =&gt

: This specifies the target file on the server. $credentials = explode(':'
