CVE-2022-24760 — AI Deep Analysis Summary

🚨 **Essence**: Prototype Pollution in Parse Server. 💥 **Consequences**: Attackers can inject malicious properties into the Object prototype, leading to **Complete System Compromise** (High CVSS).…

🛡️ **Root Cause**: **Prototype Pollution** (CWE-74). 📍 **Location**: Flaw exists in `DatabaseController.js`. The code fails to sanitize input before merging objects, allowing attackers to pollute `Object.prototype`.

📦 **Affected**: **Parse Server** versions **< 4.10.7**. 🏢 **Vendor**: parse-community. 🌐 **Product**: parse-server (Open source backend for Node.js).

💀 **Attacker Capabilities**: 1. **Modify System Behavior**: Inject properties like `__proto__` or `constructor`. 2. **Data Theft/Corruption**: Access or alter sensitive data across all instances. 3.…

🔓 **Threshold**: **LOW**. 🚫 **Auth**: No authentication required (PR:N). 🌐 **Network**: Remote (AV:N). ⚙️ **Config**: Default settings often lack strict keys, making it easy to exploit without complex configuration.

💻 **Exploit**: **YES**. Public PoC available at `https://github.com/tuo4n8/CVE-2022-24760`. 📝 **Details**: Analysis shows flow and diff commit `886bfd7`. Wild exploitation is possible due to low barrier to entry.

🔍 **Self-Check**: 1. Check Parse Server version (< 4.10.7). 2. Scan for `DatabaseController.js` usage. 3. Test for Prototype Pollution by sending payloads with `__proto__` keys in JSON bodies. 4.…

✅ **Fixed**: **YES**. 📅 **Patch Date**: 2022-03-11. 🛠️ **Fix**: Commit `886bfd7cac69496e3f73d4bb536f0eec3cba0e4d`. Upgrade to **Parse Server 4.10.7** or later immediately.

🚧 **Workaround**: 1. **Enforce Keys**: Set strict master/user keys to prevent unauthenticated DB access. 2. **Input Validation**: Sanitize all JSON inputs before processing. 3.…

⚡ **Priority**: **CRITICAL**. 📉 **CVSS**: 9.8 (High). 🚨 **Urgency**: Patch immediately. This is a remote, unauthenticated vulnerability with high impact. Do not delay.
