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.

Mahara 1.8 before 1.8.7 and 1.9 before 1.9.5 and 1.10 before 1.10.3 and 15.04 before 15.04.0 are vulnerable to server-side request forgery attacks as not all processes of curl redirects are checked against a white or black list. Employing SafeCurl will prevent issues.

Mahara 1.9 before 1.9.8 and 1.10 before 1.10.6 and 15.04 before 15.04.3 are vulnerable to perform a cross-site request forgery (CSRF) attack on the uploader contained in Mahara's filebrowser widget. This could allow an attacker to trick a Mahara user into unknowingly uploading malicious files into their Mahara account.
