Multiple SQL injection vulnerabilities in the admin section in e107 0.7.5 allow remote authenticated administrative users to execute arbitrary SQL commands via the (1) linkopentype, (2) linkrender, (3) link_class, and (4) link_id parameters in (a) links.php; the (5) searchquery parameter in (b) users.php; and the (6) download_category_class parameter in (c) download.php.

Multiple cross-site scripting (XSS) vulnerabilities in e107 0.7.5 allow remote attackers to inject arbitrary web script or HTML via the (1) ep parameter to search.php and the (2) subject parameter in comment.php (aka the Subject field when posting a comment).
