Summary
Kiwi TCMS, a test management system, had an issue with incorrect Nginx configuration that allowed potentially dangerous scripts to be executed from attachments. Versions prior to 12.5 improperly handled the `Content-Type: text/plain` header, posing a risk to users.
Risk Assessment
Organizations using Kiwi TCMS before version 12.5 were vulnerable to the execution of malicious scripts from inadequately secured attachments, potentially leading to serious security incidents.
Recommendation
It is recommended to upgrade to version 12.5 or later to benefit from fixes related to Nginx configuration and file upload validation.
Other vulnerabilities in Kiwi TCMS
See all- CVE-2026-55630Unknown
Kiwi TCMS is an open source test management system. Prior to 16.1, TestCase.extra_link and TestPlan.extra_link accepted unsanitized user input and rendered stored values verbatim, creating an opportunity for cross-site scripting. Official Docker images and unmodified Kiwi TCMS middleware send a Content-Security-Policy header that blocks inline JavaScript, making exploitation difficult in default deployments, while customized deployments that weaken those security settings may remain vulnerable. Version 16.1 properly sanitizes both fields and resets existing database records that do not validate to null. This issue is fixed in version 16.1.
- CVE-2026-54724Medium
In Kiwi TCMS prior to 16.1, the account confirmation endpoint accepted an unvalidated next parameter, allowing an unauthenticated attacker to create a URL on a trusted Kiwi TCMS hostname that redirects a victim to an arbitrary external domain. The trusted origin can support credential-harvesting pages, bypass email security filters and link-reputation checks, or deliver malware through a convincing account-confirmation lure. This issue is fixed in version 16.1.
- CVE-2023-33977High
Kiwi TCMS, a test management system, had vulnerabilities in file upload validation, allowing potentially dangerous files to be uploaded and arbitrary JavaScript execution in the browser. Additionally, Nginx's `proxy_pass` directive could strip some headers, weakening the protections of Kiwi TCMS when served behind a reverse proxy.
Original NVD description (English source)
Kiwi TCMS, an open source test management system allows users to upload attachments to test plans, test cases, etc. Versions of Kiwi TCMS prior to 12.5 had introduced changes which were meant to serve all uploaded files as plain text in order to prevent browsers from executing potentially dangerous files when such files are accessed directly. The previous Nginx configuration was incorrect allowing certain browsers like Firefox to ignore the `Content-Type: text/plain` header on some occasions thus allowing potentially dangerous scripts to be executed. Additionally, file upload validators and parts of the HTML rendering code had been found to require additional sanitation and improvements. Version 12.5 fixes this vulnerability with updated Nginx content type configuration, improved file upload validation code to prevent more potentially dangerous uploads, and Sanitization of test plan names used in the `tree_view_html()` function.
