SAP NetWeaver AS for JAVA, versions - 7.20, 7.30, 7.31, 7.40, 7.50, allows an attacker authenticated as an administrator to connect over a network and submit a specially crafted XML file in the application because of missing XML Validation, this vulnerability enables attacker to fully compromise confidentiality by allowing them to read any file on the filesystem or fully compromise availability by causing the system to crash. The attack cannot be used to change any data so that there is no compromise as to integrity.

SAP NetWeaver AS Java (CAF - Guided Procedures) - version 7.50, allows an unauthenticated attacker to submit a malicious request with a crafted XML file over the network, which when parsed will enable him to access sensitive files and data but not modify them. There are expansion limits in place so that availability is not affected.

The Create Single Payment application of SAP S/4HANA - versions 100, 101, 102, 103, 104, 105, 106, 107, 108, allows an attacker to upload the XML file as an attachment. When clicked on the XML file in the attachment section, the file gets opened in the browser to cause the entity loops to slow down the browser.

SAP Business One (B1i) - version 10.0, allows an authorized attacker to retrieve the details stack trace of the fault message to conduct the XXE injection, which will lead to information disclosure. After successful exploitation, an attacker can cause limited impact on the confidentiality and no impact to the integrity and availability.

SLD Registration in SAP HANA (fixed in versions 1.0, 2.0) does not sufficiently validate an XML document accepted from an untrusted source. The attacker can call SLDREG with an XML file containing a reference to an XML External Entity (XXE). This can cause SLDREG to, for example, continuously loop, read arbitrary files and even send local files.

SLD Registration of ABAP Platform allows an attacker to prevent legitimate users from accessing a service, either by crashing or flooding the service.

The XML parser, which is being used by SAP Enable Now, before version 1902, has not been hardened correctly, leading to Missing XML Validation vulnerability. This issue affects the file upload at multiple locations. An attacker can read local XXE files.

SAP NetWeaver (Guided Procedures), versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently validate an XML document input from a compromised admin, leading to Denial of Service.

SAP NetWeaver allows (SAP Enterprise Portal) - version 7.50, allows an authenticated attacker with sufficient privileges to access the XML parser which can submit a crafted XML file which when parsed will enable them to access but not modify sensitive files and data. It allows the attacker to view sensitive data which is owned by certain privileges.
