AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
XXE vulnerability in SAP NetWeaver Portal ReportXmlViewer allows remote attackers to read internal files and send requests to intranet servers.
Vulnerability
The XML external entity (XXE) vulnerability exists in the ReportXmlViewer component of SAP NetWeaver Portal version 7.31.201109172004 (and possibly other versions). By default, the XML parser processes external entities referenced within a user-supplied DTD, allowing attackers to include references to internal resources [1].
Exploitation
An attacker can send a crafted XML request to the ReportXmlViewer endpoint without authentication. The malicious XML includes an external entity that points to a local file or an internal network resource. The parser resolves the entity, and the content is either disclosed in the response or used to perform a request to an intranet server [1].
Impact
Successful exploitation leads to information disclosure (reading arbitrary files from the server), denial of service, or server-side request forgery (SSRF) to intranet servers. The advisory also mentions potential role upload and thread reporting [1].
Mitigation
SAP released Security Note 2111939 to fix this vulnerability. Customers should apply the patch. No workaround is documented, and other versions may be affected but were not tested [1].
