"According to its self-reported version, the MySQL Enterprise Monitor
running on the remote host may be affected by a cross-site request
forgery vulnerability due to the token generator failing to adequately
randomize the token values. A remote attacker can exploit this by
extracting a token from a form and then predicting the next token
value that will be used to secure form submissions. By convincing a
victim to visit a specially crafted form, the attacker can then use
the predicted token value to force an action for a logged in user.

Note that this vulnerability can only be exploited when the <s:token/>
tag is used within a form.");
