Description

An authenticated user can upload arbitrary files in the upload
function for collection preview images. An attacker may upload an HTML
file that includes malicious JavaScript code which will be executed if a
user visits the direct URL of the collection preview image (Stored
Cross Site Scripting). It is also possible to upload SVG files that
include nested XML entities. Those are parsed when a user visits the
direct URL of the collection preview image, which may be utilized for a
Denial of Service attack.

This issue affects edu-sharing: <8.0.8-RC2, <8.1.4-RC0, <9.0.0-RC19.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
