Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Pi-hole v3.3 & earlier suffers from **OS Command Injection** (CWE-78). <br>๐ฅ **Consequences**: Attackers can inject malicious commands via the **Allowlist** feature.โฆ
๐ก๏ธ **Root Cause**: **Improper Parameter Sanitization**. <br>๐ **Flaw**: When adding domains to the allowlist, input is not properly cleaned. This allows shell metacharacters to break out of the intended command context.โฆ
๐ฆ **Affected**: **Pi-hole** (Web Interface). <br>๐ **Versions**: **v3.3 and earlier**. <br>๐ข **Vendor**: Pi-hole LLC. <br>โ ๏ธ **Note**: Ensure you check your specific build version! ๐ง
Q4What can hackers do? (Privileges/Data)
๐ป **Attacker Power**: **Full System Control**. <br>๐ **Privileges**: The injected commands typically run with the privileges of the web server process (often root or www-data).โฆ
๐ **Threshold**: **Low/Medium**. <br>๐ **Access**: Requires access to the Pi-hole **Admin Web Interface**. <br>โ๏ธ **Config**: If the admin panel is exposed to the internet without strong auth, exploitation is trivial. ๐ช
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Exploitation**: **Yes, Public Exploits Exist**. <br>๐ **Sources**: Metasploit module (`pihole_whitelist_exec.rb`) is available. <br>๐ **Risk**: Wild exploitation is highly likely due to easy-to-use frameworks. ๐โโ๏ธ
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: <br>1. Check Pi-hole version in the dashboard. <br>2. Scan for exposed Pi-hole admin ports (usually 80/443). <br>3. Look for unauthorized domain additions in logs. <br>4.โฆ
