CVE-2022-31201Public exploitNetwork attack vector

Authenticated page manipulation via unsanitized graph parameters

Published Jul 17, 2022 · Updated Aug 3, 2024

HTML injection in SoftGuard Web before 5.1.5 allows remote authenticated users to alter pages through crafted graph GET parameters. The graph endpoint inserts the attacker-controlled h parameter into caption and table-cell HTML without proper sanitization or output encoding. A victim must visit the manipulated URL; injected markup can change displayed content or redirect the browser, while response headers block JavaScript execution.
