CVE-2017-13127
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe VIP.com application for IOS and Android allows remote attackers to obtain sensitive information and hijack the authentication of users via a rogue access point and a man-in-the-middle attack.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe VIP.com mobile applications for iOS and Android fail to properly validate SSL/TLS certificates or use insufficient transport security, allowing attackers on a compromised network (rogue access point) to intercept sensitive user data and hijack authenticated sessions via man-in-the-middle attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm VIP app installationCheck your mobile device (iOS or Android) for the 'Vip Vip' application in your installed apps list and note the installed version number.Affected if The Vip Vip application is installed on the device.
-
Verify SSL validation behaviorConfigure a proxy tool (such as Burp Suite or OWASP ZAP) to intercept network traffic from the device. Attempt to intercept HTTPS traffic from the Vip Vip app while the proxy presents an untrusted certificate.Affected if The app successfully connects and transmits data through the proxy without certificate validation errors, indicating improper SSL/TLS validation.
-
Check for HTTPS enforcementUse a network traffic analyzer (such as Wireshark or the device's built-in network logging) to observe whether the Vip Vip app makes any HTTP (non-HTTPS) connections during typical usage.Affected if The app transmits sensitive data over unencrypted HTTP connections.
-
Test certificate pinningAttempt to perform a man-in-the-middle attack using a self-signed certificate on the network. Observe whether the app rejects the invalid certificate or proceeds with the connection.Affected if The app accepts self-signed certificates or fails to reject connections with invalid certificates, indicating lack of certificate pinning.
If the Vip Vip mobile application is installed and accepts invalid SSL certificates or transmits data without encryption, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper certificate validation and certificate pinning in both iOS and Android applications, enforce HTTPS-only communications, and consider implementing additional authentication mechanisms for sensitive operations.
