Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Pi-hole v3.3 & earlier suffers from **OS Command Injection** (CWE-78). <br>π₯ **Consequences**: Attackers can inject malicious commands via the **Allowlist** feature.β¦
π‘οΈ **Root Cause**: **Improper Parameter Sanitization**. <br>π **Flaw**: When adding domains to the allowlist, input is not properly cleaned. This allows shell metacharacters to break out of the intended command context.β¦
π¦ **Affected**: **Pi-hole** (Web Interface). <br>π **Versions**: **v3.3 and earlier**. <br>π’ **Vendor**: Pi-hole LLC. <br>β οΈ **Note**: Ensure you check your specific build version! π§
Q4What can hackers do? (Privileges/Data)
π» **Attacker Power**: **Full System Control**. <br>π **Privileges**: The injected commands typically run with the privileges of the web server process (often root or www-data).β¦
π **Threshold**: **Low/Medium**. <br>π **Access**: Requires access to the Pi-hole **Admin Web Interface**. <br>βοΈ **Config**: If the admin panel is exposed to the internet without strong auth, exploitation is trivial. πͺ
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Exploitation**: **Yes, Public Exploits Exist**. <br>π **Sources**: Metasploit module (`pihole_whitelist_exec.rb`) is available. <br>π **Risk**: Wild exploitation is highly likely due to easy-to-use frameworks. πββοΈ
Q7How to self-check? (Features/Scanning)
π **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.β¦
