Detailsinfo

A vulnerability, which was classified as critical, was found in Kiuwan SAST. This affects some unknown processing of the component Scan Result Handler. The manipulation with an unknown input leads to a xml external entity reference vulnerability. CWE is classifying the issue as CWE-611. The product 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
