Sap · Sap Netweaver · CVE-2015-6662
**Name of the Vulnerable Software and Affected Versions**
SAP NetWeaver versions 7.4
**Description**
The issue exists due to a lack of access restrictions to external objects contained in links within a processed XML file. This can be exploited by a remote attacker to cause a denial of service or trigger access to an external resource using a specially crafted XML file. The vulnerability also allows remote attackers to read arbitrary files and possibly have other unspecified impact via crafted XML data.
**Recommendations**
For SAP NetWeaver version 7.4, apply the fix as described in SAP Security Note 2168485 to resolve the issue. As a temporary workaround, consider restricting access to external entities in XML files to minimize the risk of exploitation.
