DESCRIPTION:
A vulnerability has been reported in Jenkins, which can be exploited
by malicious people to conduct script insertion attacks.

Certain input passed to the winstone servlet container is not
properly sanitised in error messages before being displayed to the
user. This can be exploited to insert arbitrary HTML and script code,
which will be executed in a user's browser session in context of an
affected site when the malicious data is being viewed.

The vulnerability is reported in versions prior to 1.438 and 1.409.3.

SOLUTION:
Update to version 1.438 or 1.409.3.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Luca De Fulgentis.
