Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Directory Traversal in Ruby on Rails Action View. ๐ **Consequences**: Attackers use `..` in paths to read **arbitrary files** via the `render` method. Critical data leak risk!
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Unrestricted use of the `render` method. ๐ **Flaw**: No validation on path names, allowing directory traversal characters (`..`) to escape intended directories.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: Ruby on Rails (Rails) Action View component. ๐ **Note**: Specific versions listed as 'Ru' in data, but generally impacts older versions prior to the 2016 fix.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Hackers Can**: Read **any file** on the server. ๐พ **Data**: Sensitive configs, source code, or credentials. No RCE directly, but massive info leak.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: **LOW**. Remote exploitation possible. ๐ซ **Auth**: Likely no authentication needed if the vulnerable route is exposed. Simple URL manipulation required.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Public Exp?**: **YES**. PoC available on GitHub (e.g., `forced-request/rails-rce-cve-2016-0752`). Metasploit modules also exist. ๐ **Wild Exploitation**: Active.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Rails apps using vulnerable Action View versions. ๐งช **Test**: Try accessing URLs with `../` in the render path parameter (e.g., `/users/dashboard` variants).
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fixed**: **YES**. Patches released in Feb 2016. ๐ **Refs**: SUSE, Fedora, and official Rails advisories confirm fixes. Update immediately!
๐ฅ **Urgency**: **HIGH**. ๐ข **Priority**: Patch ASAP. Public exploits exist. Data leakage potential is severe for any unpatched Rails Action View instance.
