KAME Project Information for VU#886601

Internet Key Exchange (IKE) protocol discloses identity when Aggressive Mode shared secret authentication is used

Status

Affected

Vendor Statement

Though it is true that, with aggressive mode, identification data will be transmitted in clear, identification data can be anything - it is just a string. It doesn't necessarily reflect any of user accounts on a system.

For our implementation, the identification data is just a string, and has no relationship whatsoever with UNIX accounts or other sensitive data. Also, the shared secret used for shared secret authentication is totally separate from UNIX passwords. (of course, if a user chooses to configure identification string/shared secret to be equal to UNIX account name/password, it can be done)

So the severity really depends on how a user configures our program.
