Description Jan Lieskovsky 2011-09-12 18:00:59 UTC

A header injection flaw was found in the way the Spring Security tool processed the value of 'spring-security-redirect' parameter by user logout. A remote attacker could provide a specially-crafted URL, which once visited by a valid Spring Security tool user, could allow the attacker inject additional HTTP headers or split the response.

Sample PoC (from [1]):
=======================
<quote>
Example:
A logout link such as
/mywebapp/logout/spring-security-redirect=%0d%0a%20NewHeader%3ainjectedV
alue
could be used to inject the header
NewHeader:InjectedValue
to the response

Statement:

Not vulnerable. This issue affects the Spring Security package, which is not shipped with any Red Hat products.
