Evaluate exposed phpinfo() pages for configuration disclosure and the
prerequisites of a separate execution path. Enabled process functions do not
create RCE without an authorized code or file-execution primitive.
source-leak-hunt flags a target with info.php or phpinfo.php exposed.terminal with curl.# Step 1: Fetch phpinfo and check for exec restrictions
curl --max-time 30 --connect-timeout 10 -sk "https://TARGET/info.php" | grep -i "disable_functions"
# Step 2: If ONLY pcntl_* is disabled, all exec functions are available
# Step 3: Find upload vector and deliver webshell
| Check | What to Look For | Implication |
|---|---|---|
disable_functions | Only pcntl_alarm,pcntl_fork,... | All exec available — RCE possible |
disable_functions | exec,system,passthru,shell_exec,popen,proc_open | Exec blocked — need bypass |
allow_url_fopen | On | Remote file inclusion possible |
allow_url_include | On | RFI directly possible |
open_basedir | Not set or /var/www:/tmp | Wide file access |
display_errors | On | Error-based information disclosure |
DOCUMENT_ROOT |
/var/www/html or custom |
| Know where webshell lands |
SERVER_ADMIN | Email address | Contact for social engineering |
_SERVER["REMOTE_ADDR"] | Shows YOUR IP (if behind proxy) | WAF/CDN detection |
| PHP version | < 7.4 | EOL — more unpatched CVEs |
