Multiple vulnerabilities in the Distance Vector Multicast Routing Protocol (DVMRP) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to either immediately crash the Internet Group Management Protocol (IGMP) process or make it consume available memory and eventually crash. The memory consumption may negatively impact other processes that are running on the device.
An OS Command Injection vulnerability in the PAN-OS GlobalProtect portal allows an unauthenticated network-based attacker to execute arbitrary OS commands with root privileges. An attacker would require some level of specific information about the configuration of an impacted firewall or perform brute-force attacks to exploit this issue. This issue cannot be exploited if the GlobalProtect portal feature is not enabled. This issue impacts PAN-OS 9.1 versions earlier than PAN-OS 9.1.3; PAN-OS 8.1 versions earlier than PAN-OS 8.1.15; PAN-OS 9.0 versions earlier than PAN-OS 9.0.9; all versions of PAN-OS 8.0 and PAN-OS 7.1.
F5 released a critical Remote Code Execution vulnerability (CVE-2020-5902) on June 30th, 2020 that affects several versions of BIG-IP. This RCE vulnerability allows attackers—or any user with remote access to the Traffic Management User Interface (TMUI)— to remotely execute system commands.
Wormable vulnerabilities have the potential to spread via malware between vulnerable computers without user interaction. Windows DNS Server is a core networking component. While this vulnerability is not currently known to be used in active attacks, it is essential that customers apply Windows updates to address this vulnerability as soon as possible.
Two of the vulnerabilities directly affected Fortinet’s implementation of SSL VPN. They are: CVE-2018-13379 (FG-IR-18-384) – This is a path traversal vulnerability in the FortiOS SSL VPN web portal that could potentially allow an unauthenticated attacker to download files through specially crafted HTTP resource requests. CVE-2018-13383 (FG-IR-18-388) – This heap buffer overflow vulnerability in the FortiOS SSL VPN web portal could cause the SSL VPN web service to terminate for logged in users. It could also potentially allow remote code execution on FortiOS due to a failure to handle JavaScript href content properly. This would require an authenticated user to visit a specifically-crafted and proxied webpage.
