Host compromise via malicious content deserialization
Published Jul 8, 2025 · Updated Feb 26, 2026
Insecure deserialization in SAP NetWeaver Enterprise Portal Administration EP-RUNTIME 7.50 allows privileged users to compromise the host. SAP has not disclosed the upload handler, accepted object types, or deserialization sink that processes the untrusted content. Exploitation requires an already privileged user who can upload malicious content, and successful deserialization compromises host confidentiality, integrity, and availability.
