CVE-2022-23342: Hyland Onbase

Medium severity, CVSS 5.3. EPSS: 1.3% chance of exploitation in the next 30 days.

The Hyland Onbase Application Server releases prior to 20.3.58.1000 and OnBase releases 21.1.1.1000 through 21.1.15.1000 are vulnerable to a username enumeration vulnerability. An attacker can obtain valid users based on the response returned for invalid and valid users by sending a POST login request to the /mobilebroker/ServiceToBroker.svc/Json/Connect endpoint. This can lead to user enumeration against the underlying Active Directory integrated systems.

Affected products

• Hyland Onbase: before 20.3.58.1000 (fixed in 20.3.58.1000); from 21.1.1.1000, up to and including 21.1.15.1000
