A vulnerability classified as problematic was found in Google Android 4.3/4.4 (Smartphone Operating System). Affected by this vulnerability is some unknown functionality of the component VPN Configuration. The manipulation with an unknown input leads to a redirect vulnerability. The CWE definition for the vulnerability is CWE-601. A web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a Redirect. This simplifies phishing attacks. As an impact it is known to affect confidentiality, and integrity.

The weakness was disclosed 01/17/2014 by Mordechai Guri with Cyber Security Labs Ben Gurion University as VPN Related Vulnerability Discovered on an Android device as not defined posting (Blog). It is possible to read the advisory at cyber.bgu.ac.il. The vendor was not involved in the public release. The posting contains:

This vulnerability is similar to the previous vulnerability we've disclosed to Samsung (two weeks ago) by the fact that both of them work in a similar manner while the difference among them is the exploit target. See more info on the previous story WSJ. A detailed report on the original disclosure process will be provided soon via this blog.
Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details are unknown but a private exploit is available. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 03/29/2019). It is expected to see the exploit prices for this product increasing in the near future.The attack technique deployed by this issue is T1204.001 according to MITRE ATT&CK. The advisory points out:
This vulnerability enables malicious apps to bypass active VPN configuration (no ROOT permissions required) and redirect secure data communications to a different network address. These communications are captured in CLEAR TEXT (no encryption), leaving the information completely exposed. This redirection can take place while leaving the user completely oblivious, believing the data is encrypted and secure.

It is declared as proof-of-concept.

The posting contains the following remark:

We have earlier today contacted Google through their security email [email protected] and sent them a vulnerability alert with all relevant information in an encrypted manner. We will update this blog post when new information becomes available or when progress is made in the analysis of this vulnerability.

The vulnerability is also documented in the vulnerability database at OSVDB (102278†). Additional details are provided at threatpost.com. Be aware that VulDB is the high quality source for vulnerability data.
