Name of the Vulnerable Software and Affected Versions KRAMER VIAware versions prior to September 2021

Description The issue allows remote attackers to execute arbitrary code. This is because the ajaxPages/writeBrowseFilePathAjax.php endpoint accepts arbitrary executable pathnames. The problem exists due to an incomplete fix for a previous issue.

Recommendations For versions prior to September 2021, as a temporary workaround, consider restricting access to the ajaxPages/writeBrowseFilePathAjax.php endpoint until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
