CVE-2021-41648 — AI Deep Analysis Summary

🚨 **Essence**: Unauthenticated SQL Injection in PuneethReddyHC Online Shopping System. <br>💥 **Consequences**: Attackers can extract sensitive data from the underlying MySQL database.…

🛡️ **Root Cause**: Lack of input sanitization on the `prId` parameter in `/action.php`. <br>🔍 **CWE**: Implicitly CWE-89 (SQL Injection) due to unsanitized user input directly impacting database queries.

📦 **Affected**: PuneethReddyHC Online Shopping System Advanced. <br>👤 **Vendor**: Puneeth Reddy HC (Individual Developer). <br>🌍 **Context**: Open-source project hosted on AwesomeOpenSource.

💀 **Attacker Capabilities**: <br>1. Extract sensitive database data. <br>2. Perform Error-based & Boolean-based blind SQL injection. <br>3. No authentication required to exploit.

⚡ **Threshold**: LOW. <br>🔓 **Auth**: Unauthenticated. <br>⚙️ **Config**: No special configuration needed; simply targeting the `/action.php` endpoint with a POST request is sufficient.

🔓 **Public Exp?**: YES. <br>📂 **PoCs Available**: <br>- GitHub: MobiusBinary/CVE-2021-41648 <br>- Nuclei Templates: projectdiscovery/nuclei-templates <br>- PacketStorm Security advisory.

🔍 **Self-Check**: <br>1. Scan for `/action.php` endpoints. <br>2. Test `prId` parameter with SQL injection payloads (e.g., using SQLMap). <br>3. Look for error-based responses indicating database interaction.

🩹 **Official Fix**: Data does not indicate an official patch or version update from the individual developer. <br>⚠️ **Status**: Likely unpatched as it is a personal open-source project.

🛡️ **Workaround**: <br>1. **Block Access**: Restrict access to `/action.php` via WAF or firewall rules. <br>2. **Input Validation**: If code access is available, sanitize the `prId` parameter using prepared statements.…

🔥 **Urgency**: HIGH. <br>📉 **Priority**: Immediate action required. <br>💡 **Reason**: Unauthenticated, public PoCs exist, and it allows full database extraction. No official patch is confirmed.
