SQL injection vulnerability in the ArticleAttachment::GetAttachmentsByArticleNumber method in javascript/tinymcs/plugins/campsiteattachment/attachments.php in Campsite 3.3.5 and earlier allows remote attackers to execute arbitrary SQL commands via the article_id parameter.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
