What to do
AI-suggested
To mitigate CVE-2023-49110, European organizations should: 1) Immediately upgrade Kiuwan SAST to the fixed version master.1808.p685.q13371 or later once available. 2) If patching is not immediately possible, restrict access to the Kiuwan SAST web application and scanning modules to trusted users only, enforcing strict authentication and authorization controls. 3) Implement network segmentation to limit the Kiuwan server’s ability to initiate outbound connections to internal systems, reducing the risk of internal reconnaissance. 4) Monitor and audit scan result uploads and server logs for suspicious XML payloads or unusual file access patterns. 5) Disable or restrict XML external entity processing in the application configuration if possible, or apply XML parsing libraries that are hardened against XXE attacks. 6) Conduct regular reviews of user privileges to ensure only necessary personnel have scanning rights. 7) Employ web application firewalls (WAFs) with rules to detect and block malicious XML payloads targeting XXE vulnerabilities. 8) Educate developers and security teams about the risks of XXE and secure XML handling practices to prevent similar issues in custom integrations.
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
