CVE-2016-9465: Nextcloud Server

Medium severity, CVSS 5.4. EPSS: 1.1% chance of exploitation in the next 30 days.

Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Stored XSS in CardDAV image export. The CardDAV image export functionality as implemented in Nextcloud/ownCloud allows the download of images stored within a vCard. Due to not performing any kind of verification on the image content this is prone to a stored Cross-Site Scripting attack.

Affected products

• Nextcloud Nextcloud Server: from 10.0.0, before 10.0.1 (fixed in 10.0.1)
• ownCloud ownCloud: from 9.0.0, before 9.0.6 (fixed in 9.0.6); from 9.1.0, before 9.1.2 (fixed in 9.1.2)
