CVE-2018-19898

Vulnerability

ThinkCMF X2.2.2 contains a SQL injection vulnerability in the edit_post method of ArticleController.class.php [1]. The flaw occurs when the post[id][1] parameter is directly concatenated into SQL statements without proper sanitization. This affects the article edit_post action and is exploitable by normal authenticated users.

Exploitation

An attacker must have a valid user account on the ThinkCMF application [1]. The exploitation involves sending a crafted POST request to the article edit_post action with malicious SQL in the post[id][1] parameter. No special privileges beyond normal user authentication are required.

Impact

Successful exploitation allows an authenticated attacker to perform SQL injection, potentially leading to unauthorized data extraction, modification, or deletion from the database [1]. The attacker can access sensitive information stored in the database, including user credentials or application data.

Mitigation

The vendor has not released an official patch for CVE-2018-19898 as of the publication date [1]. ThinkCMF X2.2.2 is the affected version; users should upgrade to a patched version if available, or apply input validation and parameterized queries to the vulnerable code path as a workaround.
