Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: OS Command Injection in Reolink RLC-410W. <br>๐ฅ **Consequences**: Attackers can execute **arbitrary commands** on the device via crafted HTTP requests. Total device compromise possible.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-78** (OS Command Injection). <br>๐ **Flaw**: The network settings feature fails to sanitize inputs, allowing shell commands to be injected directly into the OS.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: **Reolink RLC-410W** (WiFi Security Camera). <br>๐ **Version**: Specifically **v3.0.0.136_20121102**. Check your firmware version immediately!
Q4What can hackers do? (Privileges/Data)
๐ **Privileges**: Likely **Root/System** level access. <br>๐ **Data**: Full control over the camera. Hackers can read, modify, or delete any data, and use the device as a pivot point.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: **Low**. <br>๐ **Auth**: Exploitable via **HTTP requests**. If the web interface is accessible (even locally), an attacker can trigger the injection without complex setup.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ข **Public Exp?**: Yes. <br>๐ **Source**: Reported by **Talos Intelligence** (TALOS-2021-1424). While specific PoC code isn't in the snippet, the vulnerability is well-documented and exploitable via HTTP.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: <br>1. Check firmware version: Is it **v3.0.0.136_20121102**? <br>2. Scan for open HTTP ports on the camera IP. <br>3. Look for network settings endpoints that accept unsanitized input.
Q8Is it fixed officially? (Patch/Mitigation)
๐ง **Fix**: **Update Firmware**. <br>๐ฅ **Action**: Visit Reolink's official support site. Download and install the latest patch for RLC-410W to close the injection hole.
Q9What if no patch? (Workaround)
๐ง **No Patch?**: <br>1. **Isolate**: Move camera to a **VLAN** with no access to critical network resources. <br>2. **Restrict**: Block external access to the camera's web interface. <br>3.โฆ
๐ฅ **Urgency**: **HIGH**. <br>โ ๏ธ **Priority**: **P1**. This is a remote code execution (RCE) vulnerability in IoT devices. Patch immediately to prevent total device takeover.
