Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: A critical **Remote Code Execution (RCE)** flaw in Dassault Systèmes DELMIA Apriso. <br>💥 **Consequences**: Attackers can take full control of the server.…
🛡️ **Root Cause**: **CWE-502**: Deserialization of Untrusted Data. <br>🔍 **Flaw**: The .NET objects within the application are processed unsafely, allowing malicious payloads to be executed upon deserialization.
Q3Who is affected? (Versions/Components)
🏢 **Affected Vendor**: Dassault Systèmes. <br>📦 **Product**: DELMIA Apriso. <br>📅 **Versions**: Release **2019** through **2024**. All versions in this range are vulnerable.
Q4What can hackers do? (Privileges/Data)
💻 **Attacker Actions**: Pre-authentication **Remote Code Execution**. <br>🔓 **Privileges**: No login required. <br>📊 **Data**: Full access to system data and configuration due to high severity (C:H, I:H, A:H).
Q5Is exploitation threshold high? (Auth/Config)
📉 **Exploitation Threshold**: **LOW**. <br>🔑 **Auth**: **None** required (PR:N). <br>🌐 **Access**: Network accessible (AV:N). <br>⚙️ **Config**: High complexity (AC:H) but no user interaction needed (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
🔓 **Public Exploit**: **YES**. <br>📜 **PoC**: Available via **ProjectDiscovery Nuclei Templates**. <br>🌍 **Status**: Automated scanning tools can detect and potentially exploit this easily.
Q7How to self-check? (Features/Scanning)
🔍 **Self-Check**: Use **Nuclei** with the specific CVE-2024-3300 template. <br>📡 **Scanning**: Look for unsafe .NET deserialization patterns in HTTP requests/responses from the affected product versions.
Q8Is it fixed officially? (Patch/Mitigation)
🩹 **Official Fix**: Refer to the **Dassault Systèmes Advisory** page. <br>📝 **Action**: Check `https://www.3ds.com/vulnerability/advisories` for the latest patch or update instructions for your specific release.
Q9What if no patch? (Workaround)
🚧 **No Patch Workaround**: <br>1. **Isolate**: Restrict network access to the application. <br>2. **WAF**: Implement Web Application Firewall rules to block suspicious .NET serialization payloads. <br>3.…
🔥 **Urgency**: **CRITICAL**. <br>⏳ **Priority**: Immediate action required. <br>🚀 **Reason**: Pre-auth RCE with public PoC means active exploitation is highly likely. Patch or mitigate NOW.
