Alkacon · Opencms · CVE-2019-11818
**Name of the Vulnerable Software and Affected Versions**
Alkacon OpenCMS versions 10.5.4 and before
**Description**
The issue concerns stored cross-site scripting (XSS) in the New User module, specifically at the "/opencms/system/workplace/admin/accounts/user new.jsp" endpoint. An attacker can insert arbitrary JavaScript as user input, such as in the `First Name` or `Last Name` fields, which will be executed whenever the affected snippet is loaded.
**Recommendations**
For versions 10.5.4 and before, consider disabling the New User module until a patch is available to prevent exploitation of the stored XSS issue. Restrict access to the "/opencms/system/workplace/admin/accounts/user new.jsp" endpoint to minimize the risk of arbitrary JavaScript execution. Avoid using the `First Name` and `Last Name` fields in the New User module until the issue is resolved.
