CVE-2021-36356
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).
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 54.4%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
