CVE-2023-40810Public exploitNetwork attack vector

Stored HTML injection via unneutralized creation fields

Published Nov 18, 2023 · Updated Aug 29, 2024

Stored HTML injection in OpenCRX 5.2.0 allows remote attackers to alter rendered product pages through crafted Product Name values. The product-creation form stores HTML from the Name, Product Name, Detailed Description, Reason, Category, and External Link fields, then renders the markup without neutralization. Public exploitation steps use the Guest account, and a victim must view the saved record; demonstrated impact is attacker-controlled page markup, not server-side code execution.
