The vulnerability is due to an authorization check that does not properly include the access level of the web interface user. An attacker who has valid application credentials could exploit this vulnerability by sending a crafted HTTP request to the web interface. A successful exploit could allow the attacker to view sensitive information that belongs to other users. The attacker could then use this information to conduct additional reconnaissance attacks. There are no workarounds that address this vulnerability.

The vulnerability is due to insufficient restrictions on the size or total amount of resources allowed via the web interface. An attacker who has valid credentials for the application could exploit this vulnerability by sending a crafted or malformed HTTP request to the web interface. A successful exploit could allow the attacker to cause oversubscription of system resources or cause a component to become unresponsive, resulting in a DoS condition.
