Mahara 1.4.x before 1.4.5 and 1.5.x before 1.5.4 allows remote authenticated administrators to execute arbitrary programs by modifying the path to clamav. NOTE: this can be exploited without authentication by leveraging CVE-2012-2243.

Cross-site scripting (XSS) vulnerability in Mahara 1.4.x before 1.4.5 and 1.5.x before 1.5.4 allows remote attackers to inject arbitrary web script or HTML by uploading an XML file with the xhtml extension, which is rendered inline as script. NOTE: this can be leveraged with CVE-2012-2244 to execute arbitrary code without authentication, as demonstrated by modifying the clamav path.
