CRITICAL 9.8EPSS 1.01%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The data of a network capture of the initial handshake phase can be used to authenticate at a SYSDBA level. If a specific .exe is not restarted often, it is possible to access the needed handshake packets between admin/client connections. Using the SYSDBA permission, an attacker can change user passwords or delete the database.
