Q1What is this vulnerability? (Essence + Consequences)
π¨ **CVE-2024-42640** is a critical **Unauthenticated Remote Code Execution (RCE)** vulnerability. It affects the `angular-base64-upload` library. Attackers can execute arbitrary code on the server.β¦
π‘οΈ **Root Cause**: Flaw in `demo/server.php`. The endpoint lacks **authentication**. It allows uploading arbitrary files. These files are then executed via `demo/uploads`.β¦
π₯ **Affected**: Users of `angular-base64-upload` library. Specifically versions **prior to v0.1.21**. Developed by Adones Pitogo. Only affects products **no longer supported** by the maintainer. β οΈ
Q4What can hackers do? (Privileges/Data)
π» **Attacker Capabilities**: Full **Remote Code Execution**. No login required. Attackers upload malicious scripts. These scripts run on the server. They can steal data. They can take over the server.β¦
π **Exploitation Threshold**: **LOW**. No authentication needed. No special configuration required. Just access the `demo/server.php` endpoint. Any public internet-facing instance is vulnerable.β¦
π **Public Exploits**: **YES**. PoCs are available on GitHub. Links: `rvizx/CVE-2024-42640` and `KTN1990/CVE-2024-42640`. Nuclei templates exist for scanning. Wild exploitation is possible. π
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `angular-base64-upload/demo/server.php`. Use Nuclei templates for automated detection. Check if `demo/uploads` is accessible. Verify library version in `package.json`.β¦
π§ **No Patch Workaround**: Since the project is **unmaintained**, patching may not be an option. **Disable** the `demo` folder entirely. Remove `server.php` and `uploads` directory. Block access via WAF rules.β¦
π¨ **Urgency**: **CRITICAL**. High severity due to unauthenticated RCE. Easy exploitation. No official support. Immediate action required. Patch or isolate immediately. Do not ignore this risk. β³
