File disclosure and SSRF via embedded iframe URLs
Published May 12, 2023 · Updated Jan 27, 2025
Path traversal and SSRF in Synapsoft pdfocus 1.17 allow remote authenticated users to read server files via uploaded documents. PDFocus processes iframe src values embedded in an uploaded DOCX, dereferencing file:// paths on the server and HTTP URLs without restricting their destination. A valid upload-capable session is required; exploitation discloses files readable by the service or reaches network resources accessible from its host.
