CVE-2023-49110

Technical Description

When the Kiuwan Local Analyzer uploads the scan results to the Kiuwan SAST web

application (either on-premises or cloud/SaaS solution), the transmitted data

consists of a ZIP archive containing several files, some of them in the

XML file format. During Kiuwan's server-side processing of these XML

files, it resolves external XML entities, resulting in a XML external

entity injection attack. An attacker with privileges to scan

source code within the "Code Security" module is able to extract any

files of the operating system with the rights of the application server

user and is potentially able to gain sensitive files, such as

configuration and passwords. Furthermore, this vulnerability also allows

an attacker to initiate connections to internal systems, e.g. for port

scans or accessing other internal functions / applications such as the

Wildfly admin console of Kiuwan.

This issue affects Kiuwan SAST: <master.1808.p685.q13371

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
