CVE-2020-11465
The /api/apps/* endpoints failed to properly validate a user's privilege, allowing an attacker to control/install helpdesk applications and leak current applications' configurations, including applications used as user sources (used for authentication).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.91%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in Deskpro before 2019.8.0. The /api/apps/* endpoints failed to properly validate a user's privilege, allowing an attacker to control/install helpdesk applications and leak current applications' configurations, including applications used as user sources (used for authentication). This enables an attacker to forge valid authentication models that resembles any user on the system.
