OVERVIEW
A vulnerability has been identified in F5 FirePass SSL VPN prior to
versions 6.1.0 HF-610-9 and 7.0.0 F-70-7. [1]
IMPACT
The vendor has provided the following details regarding this
vulnerability which has been assigned CVE-2009-4017:
"F5 FirePass SSL VPN contains a flaw that allows a remote cross-site
redirection attack. This flaw exists because the application does
not validate the refreshURL parameter upon submission to the
my.activation.cns.php3 script. As a result, a user could create a
URL that, when clicked, would redirect a victim from the intended
legitimate website to an arbitrary website of the attacker's
choosing." [1]
MITIGATION
The vendor recommends updating to the latest version of F5 FirePass SSL
VPN to correct this issue.
