CVE-2021-36356

9.8 criticalEPSS 54%

Critical (9.8) in kramerav viaware. EPSS 54% chance of exploitation in the next 30 days.

KRAMER VIAware through August 2021 allows remote attackers to execute arbitrary code because ajaxPages/writeBrowseFilePathAjax.php accepts arbitrary executable pathnames (even though browseSystemFiles.php is no longer reachable via the GUI). NOTE: this issue exists because of an incomplete fix for CVE-2019-17124.
