Can you explain this vulnerability to me?

CVE-2026-30082 is a stored cross-site scripting (XSS) vulnerability found in IngEstate Server version 11.14.0. It affects the Edit feature on the Software Package List page, where an authenticated user can inject malicious JavaScript code into parameters such as "About application," "What's news," or "Release note."

Once the malicious script is injected, it is stored on the server and executed automatically in the browsers of other users who view these sections, allowing attackers to run arbitrary web scripts or HTML.

How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability can be detected by checking for malicious JavaScript payloads injected into the parameters "About application," "What's news," or "Release note" on the Software Package List page of IngEstate Server v11.14.0.

Specifically, monitoring or inspecting API requests to the endpoint `PUT /emgui/rest/appDatasheet//?full=true` for suspicious payloads can help identify exploitation attempts.

Commands to detect this might include using web proxy tools or curl to fetch and inspect the content of these parameters for injected scripts.

• Use curl to retrieve the Software Package List page and search for suspicious script tags or payloads: `curl -k -u <user>:<password> https://<server>/emgui/rest/appDatasheet//?full=true`
• Use web application security scanners or proxy tools (e.g., Burp Suite, OWASP ZAP) to intercept and analyze requests to the Edit feature and look for injected JavaScript.

What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include restricting access to the Edit feature on the Software Package List page to trusted and authenticated users only.

Additionally, review and sanitize all inputs to the "About application," "What's news," and "Release note" parameters to prevent injection of malicious scripts.

If possible, apply any available patches or updates from the vendor addressing this vulnerability.

As a temporary measure, monitor and audit logs for suspicious activity related to the API endpoint `PUT /emgui/rest/appDatasheet//?full=true`.
