Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Crafty Controller suffers from **Server-Side Template Injection (SSTI)** in its Webhook Template component.β¦
π‘οΈ **Root Cause**: **CWE-1336** (Improper Control of Generation of Code). The flaw lies in **inadequate input sanitization** within the Webhook Template engine, allowing malicious code injection.
Q3Who is affected? (Versions/Components)
π― **Affected**: **Arcadia Technology, LLC**'s **Crafty Controller**. Specifically versions **<= 4.6.1** are vulnerable. It is a Minecraft server panel/launcher.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With RCE, hackers gain **full control** over the server. They can read, modify, or delete any data (High Impact on Confidentiality, Integrity, and Availability).
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Exploitation Threshold**: **Medium**. Requires **Authenticated** access (PR:L). However, the attack is **Remote** (AV:N) and **Low Complexity** (AC:L), making it easy to execute once logged in.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Public Exploits**: **YES**. Active PoCs are available on GitHub (e.g., by Nosiume and secdongle). Wild exploitation is likely due to the simplicity of the RCE chain.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for Crafty Controller instances. Check if the version is **4.6.1 or lower**. Look for exposed Webhook Template endpoints that accept user input without strict validation.
π§ **No Patch Workaround**: Immediately **restrict network access** to the Crafty Controller interface. Enforce **strong authentication** and consider disabling the Webhook Template feature if not essential.
Q10Is it urgent? (Priority Suggestion)
π **Urgency**: **CRITICAL**. CVSS Score indicates **High** severity (H/H/H). Given the public PoCs and RCE nature, prioritize patching or mitigation **immediately**.
