Title: Horde IMP Session Hijacking Vulnerability
Severity: HIGH
Description:
IMP is a powerful web-based mail interface/client developed by members of the Horde project.
Insufficient validation of input may allow a remote attacker an opportunity to hijack an Imp webmail session.
One of the scripts bundled with Horde IMP, 'status.php3', is prone to cross-site scripting attacks. Encoded HTML tags are not stripped from requests to access 'status.php3'. It is possible for a remote attacker to construct a link which when clicked will cause arbitrary script code to be executed in the browser of an unsuspecting user in the context of a site running Horde IMP.
As a result, it has been proven that this issue can be exploited to steal a legitimate user's cookie-based authentication credentials and gain unauthorized access to that user's webmail account.
