Page and Post Clone <= 6.3 - Authenticated (Contributor+) SQL Injection via 'meta_key' Parameter

Slug:

page-or-post-clone

Description:

The Page and Post Clone plugin for WordPress is vulnerable to SQL Injection via the 'meta_key' parameter in the content_clone() function in all versions up to, and including, 6.3. This is due to insufficient escaping on the user-supplied meta_key value and insufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injection is second-order: the malicious payload is stored as a post meta key and executed when the post is cloned.

CWE:

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

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.
