MEDIUM 5.1EPSS 0.23%

Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

A user able to connect to Agent 2 can inject an Oracle TNS connection string via the 'service' parameter. This can lead to Agent 2 connecting to an attacker-controlled server and leaking Oracle database credentials if they are saved in a named session.
