CVE-2020-5264Network attack vector

Arbitrary action via unvalidated security-page URI

Published Apr 20, 2020 · Updated Aug 4, 2024

Cross-site scripting in PrestaShop before 1.7.6.5 allows remote attackers to execute arbitrary actions via a crafted security-compromised-page URI. The compromisedAccessAction controller URL-decodes the uri query parameter and passes it to tokenized-link generation without validating that it is a safe URL, so attacker-controlled markup is reflected into the rendered page. Exploitation requires a victim to open the crafted link; script then runs in that victim's browser context and can perform actions permitted by the session.
