CVE-2020-37175 Overview
CVE-2020-37175 is a denial of service vulnerability affecting P2PWIFICAM2 for iOS version 10.4.1. The vulnerability allows attackers to crash the application by manipulating the Camera ID input field. Specifically, attackers can paste a 257-character buffer into the Camera ID field to trigger an application crash on iOS devices, resulting in a denial of service condition.
Critical Impact
This buffer overflow vulnerability in the P2PWIFICAM2 iOS application allows attackers to cause application crashes through malicious input, disrupting IP camera monitoring capabilities for affected users.

Technical Details for CVE-2020-37175
Vulnerability Analysis
This vulnerability is classified as CWE-120 (Buffer Copy without Checking Size of Input), commonly known as a classic buffer overflow. The P2PWIFICAM2 iOS application fails to properly validate the length of user-supplied input in the Camera ID field before copying it to a fixed-size buffer. When a user pastes or enters a string of 257 characters or more into the Camera ID input field, the application attempts to store this data in a buffer that cannot accommodate the input size, leading to memory corruption and subsequent application crash.
The attack requires local access and user interaction, as the malicious input must be entered directly into the application's Camera ID field. While the impact is limited to denial of service (application availability), this vulnerability demonstrates inadequate input validation practices that could potentially indicate other security weaknesses in the application's input handling routines.
Root Cause
The root cause of this vulnerability is improper bounds checking in the P2PWIFICAM2 application's Camera ID input handler. The application allocates a fixed-size buffer for storing Camera ID values but does not enforce length restrictions on user input before copying data into this buffer. When input exceeds the buffer's capacity (at or beyond 257 characters), a buffer overflow occurs, corrupting adjacent memory and causing the application to crash.
Attack Vector
The attack vector for CVE-2020-37175 is local, requiring direct interaction with the vulnerable application. An attacker must either have physical access to the device or convince a user to input malicious data. The attack scenario involves pasting or typing an overly long string (257+ characters) into the Camera ID configuration field within the P2PWIFICAM2 application. Upon processing this input, the application crashes, denying the user access to camera monitoring functionality. While user interaction is required, the attack itself requires no special privileges or authentication to execute once the application is accessible.
Detection Methods for CVE-2020-37175
Indicators of Compromise
- Unexpected crashes of the P2PWIFICAM2 application during camera configuration
- iOS crash logs showing memory access violations or buffer overflow exceptions related to P2PWIFICAM2
- User reports of application crashes when adding or modifying Camera ID settings
Detection Strategies
- Monitor iOS device logs for P2PWIFICAM2 crash reports and memory exception errors
- Implement application-level logging to track unusually long input strings in configuration fields
- Review mobile device management (MDM) solutions for application crash telemetry
Monitoring Recommendations
- Enable crash reporting for managed iOS devices to detect exploitation attempts
- Monitor for patterns of repeated application crashes that may indicate targeted denial of service
- Track P2PWIFICAM2 version deployments across the organization to identify vulnerable installations
How to Mitigate CVE-2020-37175
Immediate Actions Required
- Remove or disable P2PWIFICAM2 version 10.4.1 from iOS devices until a patched version is available
- Consider using alternative IP camera monitoring applications that have been validated for secure input handling
- Educate users not to paste untrusted or excessively long strings into the Camera ID field
Patch Information
No vendor patch information is currently available for this vulnerability. Users should monitor the application's update channels and the CNET Download Page for any security updates. Additional technical details can be found in the VulnCheck Advisory and Exploit-DB #47993.
Workarounds
- Limit Camera ID input to fewer than 257 characters when configuring cameras manually
- Use mobile device management policies to restrict or monitor application usage
- Deploy network-level camera management solutions that do not rely on the vulnerable iOS application
- Consider implementing application containerization to limit the impact of application crashes
