# Apache Conf Privilege Escalation ### [Investigation](https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/apache-conf-privilege-escalation/#investigation) ```bash ls -al /etc/apache2 -rwxrwxrwx 1 root root 7094 NOV 7 2023 apache2.conf Copied! ``` If we can modify the apache configuration file, we can update the web owner (www-data) to arbitrary user.
### [Exploitation](https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/apache-conf-privilege-escalation/#exploitation) #### [1. Update Apache.Conf](https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/apache-conf-privilege-escalation/#1.-update-apache.conf) First modify “apache.conf” file to change the web user with new one. ```bash # These need to be set in /etc/apache2/envvars User www-data Group www-data Copied! ``` #### [2. Insert Reverse Shell Script](https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/apache-conf-privilege-escalation/#2.-insert-reverse-shell-script) In the web directory (e.g. `/var/www/html`), create the script to reverse shell.\ Assume the website uses PHP, so we can create “shell.php” in the web root and insert [PHP reverse shell](https://github.com/pentestmonkey/php-reverse-shell/blob/master/php-reverse-shell.php) script. #### [3. Restart Apache Server](https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/apache-conf-privilege-escalation/#3.-restart-apache-server) #### [4. Get a Shell](https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/apache-conf-privilege-escalation/#4.-get-a-shell) We need to start a listener in local terminal. ```bash nc -lvnp 1234 Copied! ``` Then access to the web page e.g. `https://example.com/shell.php`. We should get a shell as the desired user. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
