CVE-2020-8813

Name of the Vulnerable Software and Affected Versions Cacti version 1.2.8

Description The issue in Cacti's graph realtime.php file is related to the lack of neutralization of special elements, which can be exploited by a remote attacker to execute arbitrary code by sending a specially crafted request. This can be achieved via shell metacharacters in a cookie, if a guest user has the graph real-time privilege.

Recommendations For Cacti version 1.2.8, consider disabling the graph real-time privilege for guest users until a patch is available. Restrict access to the graph realtime.php file to minimize the risk of exploitation. Avoid using shell metacharacters in cookies for the affected version. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
