1. Decoding the String

Or more simply, when considering the dot notation for directories:

high privileges

If an application naively handles this and runs with (e.g., as root user), an attacker could read: -template-..-2F..-2F..-2F..-2Froot-2F

Path Structure/Context:

In a typical file system or website structure, the path might look something like "/root" or "/root/subdirectory". For web applications, accessing the root directory (often represented as "/" or the domain name itself) is essential for configuring the site, uploading content, and managing files. Bypass simple input filters that look for

• Bypass simple input filters that look for ../ or %2e%2e%2f
• Bypass WAF rules that decode URL once but not twice
• Exploit applications that do custom decoding (e.g., replacing -2F → / before using the path)

If you’ve ever seen a URL or cookie value containing a sequence like -template-..-2F..-2F..-2F..-2Froot-2F If you’ve ever seen a URL or cookie

If an attacker successfully executes a path traversal using this method, the consequences can be catastrophic:
