Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Havoc C2 0.7 suffers from an **Unauthenticated SSRF** in demon callback handling.โฆ
๐ก๏ธ **Root Cause**: **Server-Side Request Forgery (SSRF)**. The flaw lies in how the team server processes callbacks from 'demon' agents without proper authentication or validation.โฆ
๐ฏ **Affected**: **Havoc Framework** versions **0.7** and potentially earlier (some PoCs mention 0.3-0.6 for related auth flaws). ๐ฆ It is an open-source post-exploitation C2 framework.
Q4What can hackers do? (Privileges/Data)
๐ **Capabilities**: 1. **Leak Origin IPs**: Expose team server internal network addresses. ๐ 2. **Arbitrary Traffic**: Send/read/write data via opened TCP sockets. ๐ก 3.โฆ
โก **Threshold**: **LOW to MEDIUM**. - SSRF part is **Unauthenticated**. ๐ซ๐ - RCE chaining often relies on **default hardcoded passwords** in profiles or existing auth bypasses.โฆ
๐ **Public Exploits**: **YES**. Multiple PoCs exist on GitHub (e.g., `chebuya/Havoc-C2-SSRF-poc`, `HimmeL-Byte/CVE-2024-41570-SSRF-RCE`). ๐ Automated reverse shell scripts are also available. ๐ค
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: 1. Check Havoc version (<= 0.7). ๐ 2. Scan for open TCP ports on team server via SSRF PoC. ๐ก 3. Verify if default hardcoded passwords are in use. ๐ 4.โฆ
๐ฉน **Fix**: The data implies the vulnerability exists in 0.7. Users should **update to the latest patched version** immediately. ๐ Change all default hardcoded passwords in profiles.โฆ
๐ **No Patch Workaround**: 1. **Never use default profiles** on public networks. ๐ซ 2. **Isolate** the team server from internal networks. ๐งฑ 3. **Remove** hardcoded credentials from configuration files. ๐๏ธ 4.โฆ
๐ฅ **Urgency**: **HIGH**. โ ๏ธ Since PoCs are public and chaining leads to RCE, immediate action is required. If you are running Havoc C2, assume you are compromised if using defaults. ๐จ
