A vulnerability in the Network Access Manager and Web Security Agent components of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL injection attack. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of resources that are loaded by the application at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system which, in turn, causes a malicious DLL file to be loaded when the application starts. A successful exploit could allow the attacker to execute arbitrary code on the affected machine with SYSTEM privileges.

CVE-2021-1878 [MEDIUM] Vulnerability Spotlight: Information disclosure vulnerability in macOS SMB server
Aleksandar Nikolic of Cisco Talos discovered this vulnerability. Blog by Jon Munshaw.
Cisco Talos recently discovered an exploitable integer overflow vulnerability in Apple macOS’ SMB server that could lead to information disclosure.
Server Message Block (SMB) is a network file-sharing commonly seen in Windows network environments, but macOS contains its own proprietary implementation of the server and client components. TALOS-2021-1237 (CVE-2021-1878) is an integer overflow vulnerability that exists in the way macOS SMB server processes SMB3 compounded packets. An attacker could exploit this vulnerability by sending the targeted SMB server a specially crafted packet. In addition to being able to see sensitive information, an attacker could also use the integer overflow to bypass cryptog
