ownCloud Desktop Client Vulnerability Allows Man-in-the-Middle Attacks

CVE-2015-4456

What is CVE-2015-4456?

The ownCloud Desktop Client prior to version 1.8.2 fails to properly invoke the QNetworkReply::ignoreSslErrors function with the necessary list of SSL error types. This oversight allows man-in-the-middle attackers to exploit self-signed certificates, enabling them to intercept and potentially access sensitive information without alerting the user to the certificate’s lack of validity. This vulnerability raises significant security concerns, as it undermines user trust in SSL connections.
