Detailsinfo

A vulnerability was found in Stirling-Tools Stirling-PDF up to 0.31.x. It has been declared as critical. This vulnerability affects some unknown functionality of the file src/main/resources/static/js/merge.js of the component Merge Handler. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files. In affected versions the Merge functionality takes untrusted user input (file name) and uses it directly in the creation of HTML pages allowing any unauthenticated to execute JavaScript code in the context of the user. The issue stems to the code starting at `Line 24` in `src/main/resources/static/js/merge.js`. The file name is directly being input into InnerHTML with no sanitization on the file name, allowing a malicious user to be able to upload files with names containing HTML tags. As HTML tags can include JavaScript code, this can be used to execute JavaScript code in the context of the user. This is a self-injection style attack and relies on a user uploading the malicious file themselves and it impact only them, not other users. A user might be social engineered into running this to launch a phishing attack. Nevertheless, this breaks the expected security restrictions in place by the application. This issue has been addressed in version 0.32.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
