Cross-site scripting (XSS) vulnerability in 107_plugins/content/content_manager.php in the Content Management plugin in e107 before 0.7.20, when the personal content manager is enabled, allows user-assisted remote authenticated users to inject arbitrary web script or HTML via the content_heading parameter.

Unrestricted file upload vulnerability in e107 before 0.7.20 allows remote authenticated users to execute arbitrary code by uploading a .php.filetypesphp file. NOTE: the vendor disputes the significance of this issue, noting that "an odd set of preferences and a missing file" are required.

SQL injection vulnerability in the search feature in e107 0.7.16 and earlier allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in e107 0.7.16 and earlier allow remote attackers to inject arbitrary web script or HTML via unspecified vectors in (1) submitnews.php, (2) usersettings.php; and (3) newpost.php, (4) banlist.php, (5) banner.php, (6) cpage.php, (7) download.php, (8) users_extended.php, (9) frontpage.php, (10) links.php, and (11) mailout.php in e107_admin/. NOTE: this may overlap CVE-2004-2040 and CVE-2006-4794, but there are insufficient details to be certain.

Cross-site scripting (XSS) vulnerability in email.php in e107 0.7.16 and earlier allows remote attackers to inject arbitrary web script or HTML via the HTTP Referer header in a news.1 (aka news to email) action.

SQL injection vulnerability in usersettings.php in e107 0.7.15 and earlier, when "Extended User Fields" is enabled and magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the hide parameter, a different vector than CVE-2005-4224 and CVE-2008-5320.

SQL injection vulnerability in usersettings.php in e107 0.7.13 and earlier allows remote authenticated users to execute arbitrary SQL commands via the ue[] parameter.

Unrestricted file upload vulnerability in signup.php in e107 0.7.8 and earlier, when photograph upload is enabled, allows remote attackers to upload and execute arbitrary PHP code via a filename with a double extension such as .php.jpg.

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. NOTE: an e107 developer has disputed the significance of the vulnerability, stating that "If your admins are injecting you, you might want to reconsider their access."

e107 0.75 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code via the tinyMCE_imglib_include image/jpeg parameter in e107_handlers/tiny_mce/plugins/ibrowser/ibrowser.php, as demonstrated by a multipart/form-data request. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in e107.
