A vulnerability in the Virtual Shell (VSH) session management for Cisco NX-OS Software could allow an authenticated, remote attacker to cause a VSH process to fail to delete upon termination. This can lead to a build-up of VSH processes that overtime can deplete system memory. When there is no system memory available, this can cause unexpected system behaviors and crashes. The vulnerability is due to the VSH process not being properly deleted when a remote management connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly performing a remote management connection to the device and terminating the connection in an unexpected manner. A successful exploit could allow the attacker to cause the VSH processes to fail to delete, which can lead to a system-wide denial of service (DoS) condition. The attacker must have valid user credentials to log in to the device using the remote management connection.

Cisco NX-OS Software Remote Management Memory Leak Denial of Service Vulnerability

CVE-2019-1965 [HIGH] CWE-400 Cisco NX-OS Software Remote Management Memory Leak Denial of Service Vulnerability

CVE-2013-1965 [CRITICAL] struts2: remote command execution in Showcase app
struts2: remote command execution in Showcase app
Apache Struts Showcase App 2.0.0 through 2.3.13, as used in Struts 2 before 2.3.14.3, allows remote attackers to execute arbitrary OGNL code via a crafted parameter name that is not properly handled when invoking a redirect.
Statement: A previous statement by Red Hat related to this CVE, prior to August 2019, said that Apache Struts 2 is not included in any Red Hat products. This earlier statement was incorrect. While Struts 2 is not actively compiled, shipped, used, or enabled in any Red Hat provided final products, and does not cause any vulnerability in the product, struts2-core jars have been included in some products' source code packages. The inclusion was part of an import of the Google Guice repository, which includes struts2-core

Welcome to this week’s Threat Source newsletter — the perfect place to get caught up on all things Talos from the past week.
By now, nearly everyone has heard of BlueKeep. It definitely sounds scary, with of this talk of wormable bugs and WannaCry. But so far, no attackers have used it to launch a large-scale attack.
Of course, we knew this wouldn’t stay quiet forever. Last month, Microsoft disclosed more RDP vulnerabilities in what’s being called “DejaBlue.” These are another set of wormable bugs, but we have a walkthrough for how Cisco Firepower customers can stay protected.
Elsewhere on the vulnerability front, we have advisories out for an information disclosure in Blynk-Library and two bugs in Epignosis eFront.
