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.
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).
game_score.php in e107 allows remote attackers to insert high scores via HTTP POST methods utilizing the $player_name, $player_score, and $game_name variables.
doping.php in ePing plugin 1.02 and earlier for e107 portal allows remote attackers to execute arbitrary code or overwrite files via (1) shell metacharacters in the eping_count parameter or (2) restricted shell metacharacters such as ">" and "&" in the eping_host parameter, which is not handled by the validation function.
The eping_validaddr function in functions.php for the ePing plugin for e107 portal allows remote attackers to execute arbitrary commands via shell metacharacters after a valid argument to the eping_host parameter.
ImageManager in e107 before 0.617 does not properly check the types of uploaded files, which allows remote attackers to execute arbitrary code by uploading a PHP file via the upload parameter to images.php.
