CVE-2022-38731: Qaelum Dose

Medium severity, CVSS 4.3. EPSS: 0.7% chance of exploitation in the next 30 days.

Qaelum DOSE 18.08 through 21.1 before 21.2 allows Directory Traversal via the loadimages name parameter. It allows a user to specify an arbitrary location on the server's filesystem from which to load an image. (Only images are displayed to the attacker. All other files are loaded but not displayed.) The Content-Type response header reflects the actual content type of the file being requested. This allows an attacker to enumerate files on the local system. Additionally, remote resources can be requested via a UNC path, allowing an attacker to coerce authentication out from the server to the attackers machine.

Affected products

• Qaelum Dose: from 18.08, before 21.2 (fixed in 21.2)
