CVE-2017-5887 : Vulnerability Insights and Analysis
Learn about CVE-2017-5887 affecting Starscream WebSocket.swift before 2.0.4, enabling SSL Pinning bypass. Find mitigation steps and impact details here.
In versions prior to 2.0.4, the WebSocket.swift file in Starscream has a vulnerability that enables bypassing of SSL Pinning. This occurs due to pinning taking place in the stream function, which is deemed too late. Ideally, pinning should occur in the initStreamsWithData function for enhanced security.
Understanding CVE-2017-5887
WebSocket.swift in Starscream before 2.0.4 allows an SSL Pinning bypass because pinning occurs in the stream function (this is too late; pinning should occur in the initStreamsWithData function).
What is CVE-2017-5887?
CVE-2017-5887 is a vulnerability in Starscream versions prior to 2.0.4 that allows for the bypassing of SSL Pinning due to incorrect pinning implementation timing.
The Impact of CVE-2017-5887
This vulnerability could potentially lead to unauthorized access and interception of sensitive data transmitted over insecure connections, compromising the security and privacy of users.
Technical Details of CVE-2017-5887
WebSocket.swift in Starscream before version 2.0.4 is affected by this vulnerability.
Vulnerability Description
The vulnerability allows attackers to bypass SSL Pinning by exploiting the timing of pinning implementation in the WebSocket.swift file.
