CVE-2024-52299Public exploitNetwork attack vector

Attachment disclosure via incorrectly computed access key

Published Nov 13, 2024 · Updated Nov 14, 2024

Information disclosure in XWiki SAS PDF Viewer Macro (Pro) 1.6.2 through 2.5.5 allows remote attackers to read restricted wiki attachments. XWiki.PDFViewerService calls skip on a digest stream when computing its access key, so the skipped attachment data never updates the digest and the key depends only on user identities. Attackers need the attachment reference and an authorized user's reference; private wikis additionally require an authenticated account with view access to the service.
