CVE-2014-9016 — AI Deep Analysis Summary

🚨 **Essence**: A flaw in Drupal's password hashing API allows **CPU exhaustion**.…

🛡️ **Root Cause**: Input validation error in the **password hashing API**. 📉 **Flaw**: The system fails to limit computational cost for specific inputs, leading to resource exhaustion. (CWE not specified in data).

📦 **Affected**: **Drupal 7.33** and earlier. 🔌 **Modules**: **Drupal Secure Password Hashes** (phpass) version **6.x-2.0** and earlier. 🌐 **Tech**: PHP-based CMS.

🎯 **Action**: Hackers cause **DoS** (CPU spike). 🚫 **Privileges**: No direct data theft or RCE mentioned. ⚠️ **Impact**: Service unavailability, not necessarily data breach.

⚡ **Threshold**: **Low**. 🌍 **Auth**: **Remote** exploitation possible. 📝 **Config**: No authentication required to send the crafted request. Any visitor can trigger it.

🔓 **Exploit**: **Yes**. 🐍 **PoC**: Python scripts available on GitHub (e.g., `wp_drupal_timing_attack`, `WordPress-Long-Password-Denial-of-Service`).…

🔍 **Check**: Scan for **Drupal 7.33-** or **phpass 6.x-2.0-**. 📡 **Indicator**: Look for unusual **CPU spikes** during login/password reset attempts.…

🩹 **Fix**: **Yes**. 📅 **Date**: Published **2014-11-24**. 🔗 **Source**: Official Drupal Security Advisory **SA-CORE-2014-006**. ✅ **Action**: Update to patched versions immediately.

🚧 **Workaround**: If patching is delayed, implement **rate limiting** on login/password endpoints. 🛑 **Mitigation**: Use WAF rules to block excessive hashing requests.…

🔥 **Urgency**: **High**. 📉 **Risk**: Easy remote DoS. 🚀 **Priority**: Patch immediately. 💡 **Insight**: Since PoCs are public, active exploitation is likely. Don't wait!
