AI-suggested
Organizations should immediately audit their Liferay Portal and DXP deployments to identify affected versions and restrict SVG file uploads where possible. Implement strict input validation and sanitization for SVG files, ensuring that any embedded scripts or potentially dangerous elements are removed before processing or rendering. Employ Content Security Policy (CSP) headers to restrict script execution origins and reduce the impact of any injected scripts. Monitor web server and application logs for unusual SVG upload activity or anomalous user behavior. Where feasible, upgrade to the latest Liferay versions once patches addressing this vulnerability are released. In the interim, consider disabling or limiting the Commerce diagram-type product features that accept SVG inputs. Educate users about the risks of interacting with untrusted content and enforce least privilege principles to minimize the impact of potential exploitation. Regularly review and update web application firewalls (WAFs) to detect and block malicious payloads targeting this vulnerability.
Description
Stored cross-site scripting (XSS) vulnerability in diagram type products in Commerce in Liferay Portal 7.4.3.18 through 7.4.3.111, and Liferay DXP 2023.Q4.0 through 2023.Q4.5, 2023.Q3.1 through 2023.Q3.8, and 7.4 update 18 through update 92 allows remote attackers to inject arbitrary web script or HTML via a crafted payload injected into a SVG file.
