Vulnerability Title
User Access Manager <= 2.3.12 - Authenticated (Subscriber+) SQL Injection
Vulnerability Description
The User Access Manager plugin for WordPress is vulnerable to Second-Order SQL Injection via the 'id' parameter of the wp_ajax_save-attachment-compat AJAX action in versions up to, and including, 2.3.12. This is due to insufficient validation on the objectId value stored in the saveAjaxAttachmentData() function and subsequent unparameterized concatenation in the addQueryExcludedPostFilter() function — the stored value is later retrieved from the database and used as an array key, then directly imploded into a SQL NOT IN() clause without integer casting or prepared statements. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

WordPress User Access Manager SQL注入漏洞
Vulnerability Description
WordPress User Access Manager是WordPress基金会的一个用户访问与权限管理工具。 WordPress User Access Manager 2.3.12及之前版本存在SQL注入漏洞,该漏洞源于对wp_ajax_save-attachment-compat AJAX操作中'id'参数验证不足,存储的objectId值未经过滤,后续未参数化拼接导致二阶SQL注入,可能使经过身份验证的攻击者(订阅者级别及以上)向现有SQL查询追加额外查询,从而提取数据库敏感信息。
