A vulnerability, which was classified as critical, was found in RIM BlackBerry 10. This affects an unknown functionality of the component POP/IMAP. The manipulation of the argument Credentials with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality, and integrity.

The weakness was shared 07/17/2013 by Frank Rieger and Marc Heuse as Blackberry 10 macht E-Mail-Passworte für NSA und GCHQ zugreifbar as confirmed blog post (Website). It is possible to read the advisory at frank.geekheim.de. The vendor was not involved in the public release. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/19/2019). The attack technique deployed by this issue is T1592 according to MITRE ATT&CK. Due to its background and reception, this vulnerability has a historic impact. The advisory points out:

When you enter your POP / IMAP e-mail credentials into a Blackberry 10 phone they will be sent to Blackberry without your consent or knowledge. A server with the IP 68.171.232.33 which is in the Research In Motion (RIM) netblock in Canada will instantly connect to your mailserver and log in with your credentials. If you do not have forced SSL/TLS configured on your mail server, your credentials will be sent in the clear by Blackberrys server for the connection. Blackberry thus has not only your e-mail credentials stored in its database, it makes them available to anyone sniffing inbetween – namely the NSA and GCHQ as documented by the recent Edward Snowden leaks.

A public exploit has been developed by Frank Rieger/Marc Heuse and been published immediately after the advisory. The exploit is shared for download at frank.geekheim.de. It is declared as highly functional. We expect the 0-day to have been worth approximately $5k-$25k.

It is possible to mitigate the problem by applying the configuration setting Advanced Option. The problem might be mitigated by replacing the product with Apple iPhone as an alternative. The best possible mitigation is suggested to be the change of configuration settings. A possible mitigation has been published 1 days after the disclosure of the vulnerability.
