Detailsinfo

A vulnerability, which was classified as critical, has been found in Red Hat JBoss EAP 7.0 (Application Server Software). This issue affects some unknown functionality of the component JAXP. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

It was found that the JAXP implementation used in JBoss EAP 7.0 for XSLT processing is vulnerable to code injection. An attacker could use this flaw to cause remote code execution if they are able to provide XSLT content for parsing. Doing a transform in JAXP requires the use of a 'javax.xml.transform.TransformerFactory'. If the FEATURE_SECURE_PROCESSING feature is set to 'true', it mitigates this vulnerability.

The bug was discovered 01/29/2018. The weakness was disclosed 06/27/2018 with Red Hat as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. The identification of this vulnerability is CVE-2017-7465 since 04/05/2017. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.
