CVE-2015-7298: ownCloud Desktop Client

Medium severity, CVSS 5.1. EPSS: 0.7% chance of exploitation in the next 30 days.

ownCloud Desktop Client before 2.0.1, when compiled with a Qt release after 5.3.x, does not call QNetworkReply::ignoreSslErrors with the list of errors to be ignored, which makes it easier for remote attackers to conduct man-in-the-middle (MITM) attacks by leveraging a server using a self-signed certificate. NOTE: this vulnerability exists because of a partial CVE-2015-4456 regression.

Affected products

• ownCloud ownCloud Desktop Client: up to and including 2.0.0
• Qt Qt: version 5.3.0 only; version 5.4.1 only
