Catalyst It · Mahara · CVE-2011-2771
**Name of the Vulnerable Software and Affected Versions**
Mahara versions prior to 1.4.1
**Description**
The issue concerns multiple cross-site scripting (XSS) vulnerabilities. These vulnerabilities allow remote attackers to inject arbitrary web script or HTML. The vulnerabilities are related to URI attributes and the External Feed component. An example of exploitation is through the guid element in an RSS feed.
**Recommendations**
