Description
Piwigo is an open source photo gallery application for the web. Prior to version 16.3.0, the four date filter parameters (f_min_date_available, f_max_date_available, f_min_date_created, f_max_date_created) in ws_std_image_sql_filter() are concatenated directly into SQL without any escaping or type validation. This could result in an unauthenticated attacker reading the full database, including user password hashes. This issue has been patched in version 16.3.0.
Analysis
SQL injection in Piwigo photo gallery application versions prior to 16.3.0 allows unauthenticated remote attackers to extract the entire database, including user password hashes, via unsanitized date filter parameters in the ws_std_image_sql_filter() function. The vulnerability stems from direct SQL concatenation of four date parameters without input validation or escaping. …
