CVE-2023-30838
No affected components available
PrestaShop is an Open Source e-commerce web application. Prior to versions 8.0.4 and 1.7.8.9, the ValidateCore::isCleanHTML() method of Prestashop misses hijackable events which can lead to cross-site scripting (XSS) injection, allowed by the presence of pre-setup @keyframes methods. This XSS, which hijacks HTML attributes, can be triggered without any interaction by the visitor/administrator, which makes it as dangerous as a trivial XSS attack. Contrary to other attacks which target HTML attributes and are triggered without user interaction (such as onload / onerror which suffer from a very limited scope), this one can hijack every HTML element, which increases the danger due to a complete HTML elements scope. Versions 8.0.4 and 1.7.8.9 contain a fix for this issue.
The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
