Authenticated script injection via IpUtil.getIpAddr

Published Dec 8, 2022 · Updated Aug 3, 2024

Cross-site scripting in IpUtil.getIpAddr in LinZhaoguan pb-cms 2.0 allows remote authenticated users to inject script through a request. The public record names IpUtil.getIpAddr but does not disclose which input reaches an HTML sink or where the returned value is rendered. A low-privileged user must supply the input and another user must view the affected page, enabling script execution in that viewer's browser.
