Official description

Insufficient verification of data authenticity vulnerability in Delinea Secret Server, in its v10.9.000002 version. An attacker with an administrator account could perform software updates without proper integrity verification mechanisms. In this scenario, the update process lacks digital signatures and fails to validate the integrity of the update package, allowing the attacker to inject malicious applications during the update.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Insufficient Verification of Data Authenticity

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
