CVE-2023-41642Public exploitNetwork attack vector

Browser script execution via unsanitized error reflection

Published Aug 31, 2023 · Updated Oct 1, 2024

Reflected XSS in ErroreNonGestito.aspx in GruppoSCAI RealGimm 1.1.37p38 allows remote attackers to execute JavaScript in a victim's browser. Malformed VIEWSTATE data causes an error redirect whose response reflects the unencoded parameter, Referer, or User-Agent values into executable page content. Exploitation requires a victim to load the attacker-crafted response; script execution occurs in the RealGimm origin and is bounded to the victim's browser session.
