CVE-2026-42370 — AI Deep Analysis Summary

🚨 **Essence**: A Stack Buffer Overflow in the WebCam Server login function. 💥 **Consequences**: Attackers can trigger **Arbitrary Code Execution (ACE)** by sending crafted HTTP requests.…

🛡️ **Root Cause**: **CWE-787** (Out-of-bounds Write). The flaw lies in how the login function handles input data, leading to stack corruption when boundaries are exceeded.

📦 **Affected**: **GeoVision Inc.** products. Specifically **GV-VMS V20** version **20.0.2**. The vulnerable component is the **WebCam Server**.

💀 **Attacker Capabilities**: Full **Arbitrary Code Execution**. Since it's a stack overflow, attackers can run malicious code with the privileges of the vulnerable service, potentially taking over the server.

🔓 **Exploitation Threshold**: **Low**. **No Authentication (PR:N)** is required. Attackers can send the malicious HTTP request directly from the network (**AV:N**) without logging in first.

📜 **Public Exploit**: **No**. The `pocs` field is empty. While the vulnerability is known, there are no public Proof-of-Concept (PoC) scripts or wild exploits listed in the data yet.

🔍 **Self-Check**: Scan for **GeoVision GV-VMS V20** services. Look for the **WebCam Server** login endpoint. Check if the version is specifically **20.0.2**. Use network scanners to detect unauthenticated access points.

🩹 **Official Fix**: **Yes**. The vendor **GeoVision Inc.** has published an advisory. Check their official cybersecurity page for patches or updates to resolve the stack overflow issue.

🚧 **No Patch Workaround**: If you cannot patch immediately, **restrict network access** to the WebCam Server login port. Use firewalls to block unauthenticated HTTP requests from external networks.…

⚠️ **Urgency**: **High Priority**. Despite **High Complexity (AC:H)** in CVSS, the lack of authentication (**PR:N**) and the severity of **Code Execution (C:H/I:H/A:H)** make this critical.…
