This issue affects some unknown processing of the file publiccms-parent/publiccms/src/main/webapp/resource/plugins/pdfjs/viewer.html. The manipulation of the argument File leads to open redirect. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The patch is named f1af17af004ca9345c6fe4d5936d87d008d26e75. It is recommended to apply a patch to fix this issue.

AnalysisAI

Open redirect vulnerability in Sanluan PublicCMS up to version 5.202506.a allows authenticated remote attackers to redirect users to arbitrary URLs via manipulation of the File parameter in the PDF.js viewer component, requiring user interaction to trigger the redirect. The vulnerability has publicly available exploit code and affects the PDF viewer resource file, though real-world impact is limited by the requirement for prior authentication and user click interaction.

Technical ContextAI

The vulnerability exists in the PDF.js viewer component located at publiccms-parent/publiccms/src/main/webapp/resource/plugins/pdfjs/viewer.html. PDF.js is a popular JavaScript PDF rendering library, and the vulnerability stems from improper validation of the File parameter input, allowing attackers to craft malicious URLs that bypass URL validation checks. This is classified as CWE-601 (URL Redirection to Untrusted Site), a common attack vector in web applications where user-supplied input is used to construct redirect targets without proper sanitization. The vulnerability affects PublicCMS versions through 5.202506.a via the CPE cpe:2.3:a:publiccms:publiccms:*:*:*:*:*:*:*:*.

RemediationAI

Apply the vendor-released patch immediately by upgrading to the version containing commit f1af17af004ca9345c6fe4d5936d87d008d26e75 or later. Organizations should obtain the patched version from the official Sanluan PublicCMS GitHub repository at https://github.com/sanluan/PublicCMS/commit/f1af17af004ca9345c6fe4d5936d87d008d26e75. As a temporary compensating control if immediate patching is not feasible, restrict access to the PDF viewer functionality to trusted internal users only by implementing network-level access controls to the publiccms/resource/plugins/pdfjs/viewer.html endpoint, though this may impact legitimate PDF viewing functionality. Additionally, implement Content Security Policy (CSP) headers to restrict redirect targets and validate all user-supplied URL parameters before use.
