[R2] HP OpenView Performance Insight sendEmail.jsp bgcolor Parameter Reflected XSS

Medium

Synopsis

HP OpenView Performance Insight contains a flaw that allows for a reflected cross-site scripting (XSS) attack. This flaw exists because the sendEmail.jsp script does not validate input to the 'bgcolor' parameter before returning it to users. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.

Note, additional XSS issues were reported to HP at the same time, but the original report has been lost unfortunately. Yes, we're sad too.

Solution

HP has released a patch to address this issue.
