CVE-2009-2898: Stored XSS in alerts list

Severity: Moderate

Vendor: SpringSource

Versions Affected: Hyperic HQ 3.2, 4.0, 4.1, 4.2-beta1. Earlier,
unsupported versions may also be affected

Description:
An authenticated Hyperic user can create an alert with JavaScript code
in the Description field. When a user visits the Alerts list, the
Description field of every alert is displayed without properly escaping
especial HTML characters, thus leading to a persistent XSS.

Mitigation:
3.2 users should upgrade to 3.2.6 and then apply the 3.2.6.1 patch
4.0 users should upgrade to 4.0.3 and then apply the 4.0.3.1 patch
4.1 users should upgarde to 4.1.2 and then apply the 4.1.2.1 patch
4.2-beta1 users should upgrade to 4.2-beta2 or later
To protect against this issue until patches have been applied, system
administrators should ensure untrusted users do not have the necessary
privileges to create alerts.

Credit:
This vulnerability was discovered and researched by Gastón Rey and Pablo
Carballo from Core Security Technologies during Core Bugweek 2009.
