-include-..-2f..-2f..-2f..-2froot-2f __top__ Review
The CMS used include($_GET['template'] . '.tpl') . Due to improper input filtering and the server running as root (a terrible practice), the attacker read /root/.bashrc and discovered database credentials, leading to a full compromise. The fix was to implement a whitelist and move the web server to a non-privileged account.
If successful, the web application reads and returns: /root/etc/passwd (unlikely) or /root/.bashrc or attempts to include a malicious file from /root/uploaded.txt .
Before processing any file path, resolve it to its absolute, real path and verify that it remains within the intended base directory. In , use File.getCanonicalPath() . -include-..-2F..-2F..-2F..-2Froot-2F
: This represents /root/ , the home directory for the system administrator (root user) on Linux-based systems. Why This Vulnerability Exists
But a more robust detection rule would decode potential URL‑encoded strings before matching. The CMS used include($_GET['template']
Use tools like:
Even with an appended extension, attackers can use “log poisoning”. If the -include-..-2F..-2F..-2F..-2Froot-2F pattern is used to include server logs (e.g., /var/log/apache2/access.log ), and the attacker has previously injected PHP code into the log via the User-Agent header, including that log file may execute the code. The path traversal allows reaching /var/log/ from the web root. The fix was to implement a whitelist and
Remember: The safest way to handle file inclusion is to not include files dynamically at all. If you must, let a whitelist be your shield, and canonicalization your sword.
need to write a long article for the keyword: "-include-..-2F..-2F..-2F..-2Froot-2F". This looks like a URL-encoded path traversal payload: -include-..-2F..-2F..-2F..-2Froot-2F. Decoding: -include-../../../../root/ . Actually, %2F is slash, so ..%2F is ../. So the string is "-include-../../../../root/" but with hyphens? The keyword includes "-include-" prefix and then ..-2F etc. So the article should be about path traversal attacks, specifically using include directives to access root files. Possibly related to Local File Inclusion (LFI) vulnerabilities. Write a comprehensive article explaining this payload, how it works, prevention, etc. The keyword is odd but likely a test for SEO. We'll produce a detailed technical article. Understanding the Path Traversal Payload: -include-..-2F..-2F..-2F..-2Froot-2F
