CVE-2021-43789Network attack vector

Database disclosure via unvalidated search ordering inputs

Published Dec 7, 2021 · Updated Aug 4, 2024

Blind SQL injection in PrestaShop 1.7.5.0 through 1.7.8.1 allows remote attackers to read database data through search filters. The Filters accessors returned untrusted orderBy and sortOrder values that query builders inserted as SQL ordering syntax without strict field-name and direction validation. No account or user interaction is required; the blind channel exposes database content through observable response differences rather than direct query output.
