1. 5. How to test safely (for defenders)

   If you’re testing your own application and see such strings in logs: -template-..-2F..-2F..-2F..-2Froot-2F

   1. Match an allowed prefix (/var/www/templates/)
   2. Then escape via ../ to read /etc/passwd or /root/.ssh/id_rsa

   Recommended Defense:

   1.3 The Full Decoding

   • Original: -template-..-2F..-2F..-2F..-2Froot-2F
   • Replace -2F with /: -template-../../../../root/
   • Interpreted path: starting from the template directory, go up four levels (../../../../), then enter the root/ directory.

   In a standard web application, the server is supposed to restrict a user's access to the "Public" folder (where HTML, CSS, and JS files live). Match an allowed prefix ( /var/www/templates/ ) Then

   Why the Double Encoding (-2F instead of %2F)?

   Attackers use obfuscation to bypass naïve input filters. A filter might block %2F or .., but if the application decodes -2F to / at a later stage (e.g., custom middleware), the attacker can smuggle the payload through. In a standard web application

   (or Directory Traversal) vulnerabilities in web applications. This specific format is designed to bypass security filters by using "dot-dot-slash" sequences that are URL-encoded ) and potentially prefixed with a keyword like -template- to trick the application's routing or template engine. 1.
