CVE-2022-20922
https://notcve.org/view.php?id=CVE-2022-20922
Multiple vulnerabilities in the Server Message Block Version 2 (SMB2) processor of the Snort detection engine on multiple Cisco products could allow an unauthenticated, remote attacker to bypass the configured policies or cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to improper management of system resources when the Snort detection engine is processing SMB2 traffic. An attacker could exploit these vulnerabilities by sending a high rate of certain types of SMB2 packets through an affected device. A successful exploit could allow the attacker to trigger a reload of the Snort process, resulting in a DoS condition. Note: When the snort preserve-connection option is enabled for the Snort detection engine, a successful exploit could also allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. The snort preserve-connection setting is enabled by default. See the Details ["#details"] section of this advisory for more information. Note: Only products that have Snort 3 configured are affected. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-smb-3nfhJtr • CWE-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection') •
CVE-2017-12350
https://notcve.org/view.php?id=CVE-2017-12350
A vulnerability in Cisco Umbrella Insights Virtual Appliances 2.1.0 and earlier could allow an authenticated, local attacker to log in to an affected virtual appliance with root privileges. The vulnerability is due to the presence of default, static user credentials for an affected virtual appliance. An attacker could exploit this vulnerability by using the hypervisor console to connect locally to an affected system and then using the static credentials to log in to an affected virtual appliance. A successful exploit could allow the attacker to log in to the affected appliance with root privileges.
