CVE-2022-2458
Description
An XML external entity injection(XXE) vulnerability was found in Business Central. This flaw allows an attacker to interfere with an application's processing of XML data. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. The software processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. Here, the XML external entity injection leads to External Service interaction and an Internal file read in Business Central and Kie-Server APIs.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
