Even if the traversal is successful, the payload targets /root/ .
The attacker changes the URL to: https://example.com -template-..-2F..-2F..-2F..-2Froot-2F
Before writing, define your "root" purpose to ensure the content provides value. Even if the traversal is successful, the payload
In a vulnerable web app (e.g., file read via ?file= parameter), an attacker might try: The string -template-
: Use built-in language functions to resolve paths to their absolute form (e.g., realpath() in PHP) and verify they still reside within the intended directory.
The string -template-..-2F..-2F..-2F..-2Froot-2F serves as a reminder of the "cat-and-mouse" game between security researchers and hackers. While it looks like gibberish to the average user, to a security professional, it represents a fundamental vulnerability in how computers interpret instructions.
Some applications write user-controlled data to log files, then allow template inclusion. A payload like -template-../../../../../var/log/apache2/access.log could lead to log file inclusion and eventual remote code execution.
