Description
YesWiki before 4.7.0 contains a sql injection vulnerability in despam.php where the from parameter is escaped but placed in an unquoted INTERVAL position. Authenticated administrators can inject SQL via the from POST parameter to perform blind reads of the database including user password hashes.
A SQL injection vulnerability has been identified in YesWiki versions prior to 4.7.0, specifically within the despam.php file.
