CVE-2025-69624 Details
Description
Nitro PDF Pro before 14.43 for Windows contains a NULL pointer dereference vulnerability in the JavaScript implementation of app.alert(). When app.alert() is called with more than one argument and the first argument evaluates to null (for example, app.alert(app.activeDocs, true) when app.activeDocs is null), the engine routes the call through a fallback path intended for non-string arguments. In this path, js_ValueToString() is invoked on the null value and returns an invalid string pointer, which is then passed to JS_GetStringChars() without validation. Dereferencing this pointer leads to an access violation and application crash when opening a crafted PDF. For example, 14.41.1.4 and 14.42.0.34 have been reported as vulnerable.
A NULL pointer dereference vulnerability has been identified in Nitro PDF Pro for Windows, version 14.41.1.4. The issue arises in the JavaScript implementation of the app.alert() function. When app.alert() is invoked with multiple arguments, and the first argument is null (such as when app.activeDocs is null), the JavaScript engine redirects the call through a fallback intended for non-string arguments. This fallback invokes js_ValueToString() on the null value, which returns an invalid string pointer. This pointer is then passed to JS_GetStringChars() without proper validation, leading to a dereferencing of the pointer that causes an access violation and crashes the application. The vulnerability can be exploited by opening a specially crafted PDF that triggers this behavior.
