Security Vulnerabilities - CVEs Published In August 2020
A denial of service vulnerability exists in Windows Remote Desktop Gateway (RD Gateway) when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could cause the RD Gateway service on the target system to stop responding.
To exploit this vulnerability, an attacker would need to run a specially crafted application against a server which provides RD Gateway services.
The update addresses the vulnerability by correcting how RD Gateway handles connection requests.

An elevation of privilege vulnerability exists when Windows improperly handles hard links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.
The security update addresses the vulnerability by correcting how Windows handles hard links.

A remote code execution vulnerability exists in Visual Studio Code when it process environment variables after opening a project. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would need to convince a target to clone a repository and open it in Visual Studio Code. Attacker-specified code would execute when the target opened the integrated terminal.
The update address the vulnerability by modifying the way Visual Studio Code handles environment variables.

Multiple vulnerabilities in the user interface of Cisco Webex Meetings Desktop App could allow an authenticated, remote attacker to obtain restricted information from other Webex users. These vulnerabilities are due to improper input validation of parameters returned to the application from a web site. An attacker with a valid Webex account could exploit these vulnerabilities by persuading a user to follow a URL that is designed to return malicious path parameters to the affected software. A successful exploit could allow the attacker to obtain restricted information from other Webex users.

A vulnerability in the interprocess communication (IPC) channel of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted IPC message to the AnyConnect process on an affected device. A successful exploit could allow the attacker to stop the AnyConnect process, causing a DoS condition on the device. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system.

A vulnerability in the interprocess communication (IPC) channel of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to overwrite VPN profiles on an affected device. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted IPC message to the AnyConnect process on an affected device. A successful exploit could allow the attacker to modify VPN profile files. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system.

A vulnerability in the CLI of Cisco AsyncOS for Cisco Email Security Appliance (ESA) and Cisco AsyncOS for Cisco Content Security Management Appliance (SMA) could allow an authenticated, remote attacker to access sensitive information on an affected device. The vulnerability is due to excessive verbosity in certain log subscriptions. An attacker could exploit this vulnerability by accessing specific log files on an affected device. A successful exploit could allow the attacker to obtain sensitive log data, which may include user credentials. To exploit this vulnerability, the attacker would need to have valid credentials at the operator level or higher on the affected device.

A vulnerability in an access control mechanism of Cisco Cyber Vision Center Software could allow an unauthenticated, remote attacker to bypass authentication and access internal services that are running on an affected device. The vulnerability is due to insufficient enforcement of access control in the software. An attacker could exploit this vulnerability by directly accessing the internal services of an affected device. A successful exploit could allow an attacker to impact monitoring of sensors that are managed by the software.

A vulnerability in the Border Gateway Protocol (BGP) additional paths feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to prevent authorized users from monitoring the BGP status and cause the BGP process to stop processing new updates, resulting in a denial of service (DOS) condition. The vulnerability is due to an incorrect calculation of lexicographical order when displaying additional path information within Cisco IOS XR Software, which causes an infinite loop. An attacker could exploit this vulnerability by sending a specific BGP update from a BGP neighbor peer session of an affected device; an authorized user must then issue a show bgp command for the vulnerability to be exploited. A successful exploit could allow the attacker to prevent authorized users from properly monitoring the BGP status and prevent BGP from processing new updates, resulting in outdated information in the routing and forwarding tables.

A vulnerability in the web-based management interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of the affected service. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected service. An attacker could exploit this vulnerability by persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
