CVE-2021-35215 — AI Deep Analysis Summary

🚨 **Essence**: Insecure Deserialization in SolarWinds Orion Platform. <br>💥 **Consequences**: Remote Code Execution (RCE). Attackers can run arbitrary code on the server.…

🛡️ **CWE**: CWE-502 (Deserialization of Untrusted Data). <br>🔍 **Flaw**: The platform processes untrusted input during deserialization in version 2020.2.5, allowing malicious payloads to execute.

🏢 **Vendor**: SolarWinds. <br>📦 **Product**: Orion Platform. <br>📅 **Affected Version**: Specifically noted as **2020.2.5** in the description. Check if older versions are also vulnerable.

👑 **Privileges**: Remote Code Execution (RCE). <br>📂 **Data**: Full control over the server. Can read/write files, install backdoors, and pivot to other network devices. <br>🌐 **Scope**: Server-Side (S:C in CVSS).

🔐 **Auth Required**: **YES**. <br>⚠️ **Threshold**: Medium. The PoC requires valid login credentials. <br>📝 **Note**: CVSS indicates PR:L (Low Privileges) needed, not necessarily Admin, but authentication is a barrier.

💻 **Public Exploit**: **YES**. <br>🔗 **PoC**: Available on GitHub (Y4er/CVE-2021-35215). <br>🎯 **Target**: `POST /Orion/RenderControl.aspx`.…

🔍 **Self-Check**: <br>1. Verify if you are running SolarWinds Orion Platform. <br>2. Check version is **2020.2.5** or potentially earlier. <br>3. Scan for the endpoint `/Orion/RenderControl.aspx`. <br>4.…

🩹 **Official Fix**: **YES**. <br>📄 **Reference**: SolarWinds released patch in **Orion Platform 2020.2.6**. <br>🔗 **Link**: See SolarWinds Trust Center advisory for details.

🚧 **No Patch Workaround**: <br>1. **Restrict Access**: Block external access to `/Orion/RenderControl.aspx`. <br>2. **Network Segmentation**: Isolate Orion servers. <br>3.…

⚡ **Urgency**: **HIGH**. <br>🚨 **Priority**: Patch immediately. <br>💡 **Reason**: RCE vulnerability with public PoC. Even though auth is required, the impact is critical. Do not delay updating to 2020.2.6 or later.
