Security Vulnerabilities
- CVEs Published In September 2020
A vulnerability in the web interface of Cisco Managed Services Accelerator (MSX) could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user's HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. A successful exploit could allow the attacker to redirect a user to a malicious web page. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites.
A vulnerability in the implementation of the Lua interpreter integrated in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to execute arbitrary code with root privileges on the underlying Linux operating system of an affected device. The vulnerability is due to insufficient restrictions on the allowed Lua function calls within the context of user-supplied Lua scripts. A successful exploit could allow the attacker to trigger a heap overflow condition and execute arbitrary code with root privileges on the underlying Linux operating system of an affected device.
A vulnerability in the web UI of Cisco Small Business Switches could allow an unauthenticated, remote attacker to access sensitive device information. The vulnerability exists because the software lacks proper authentication controls to information accessible from the web UI. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web UI of an affected device. A successful exploit could allow the attacker to access sensitive device information, which includes configuration files.
A vulnerability in the automatic update process of Cisco Umbrella Roaming Client for Windows could allow an authenticated, local attacker to install arbitrary, unapproved applications on a targeted device. The vulnerability is due to insufficient verification of the Windows Installer. An attacker could exploit this vulnerability by placing a file in a specific location in the Windows file system. A successful exploit could allow the attacker to bypass configured policy and install unapproved applications.
A vulnerability in the REST API endpoint of Cisco Vision Dynamic Signage Director could allow an unauthenticated, remote attacker to bypass authentication on an affected device. The vulnerability is due to missing authentication on some of the API calls. An attacker could exploit this vulnerability by sending a request to one of the affected calls. A successful exploit could allow the attacker to interact with some parts of the API.
A vulnerability in the inter-service communication of Cisco AnyConnect Secure Mobility Client for Android could allow an unauthenticated, local attacker to perform a service hijack attack on an affected device or cause a denial of service (DoS) condition. The vulnerability is due to the use of implicit service invocations. An attacker could exploit this vulnerability by persuading a user to install a malicious application. A successful exploit could allow the attacker to access confidential user information or cause a DoS condition on the AnyConnect application.
A vulnerability in the web UI of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. If the user has administrative privileges, the attacker could alter the configuration, execute commands, or reload an affected device.
A vulnerability in the Operations, Administration, Maintenance and Provisioning (OAMP) OpsConsole Server for Cisco Unified Customer Voice Portal (CVP) could allow an authenticated, remote attacker to execute Insecure Direct Object Reference actions on specific pages within the OAMP application. The vulnerability is due to insufficient input validation on specific pages of the OAMP application. An attacker could exploit this vulnerability by authenticating to Cisco Unified CVP and sending crafted HTTP requests. A successful exploit could allow an attacker with administrator or read-only privileges to learn information outside of their expected scope. An attacker with administrator privileges could modify certain configuration details of resources outside of their defined scope, which could result in a denial of service (DoS) condition.
Multiple vulnerabilities in the implementation of Border Gateway Protocol (BGP) Ethernet VPN (EVPN) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerabilities are due to incorrect processing of BGP update messages that contain crafted EVPN attributes. An attacker could exploit these vulnerabilities by sending BGP EVPN update messages with malformed attributes to be processed by an affected system. A successful exploit could allow the attacker to cause the BGP process to restart unexpectedly, resulting in a DoS condition. The Cisco implementation of BGP accepts incoming BGP traffic only from explicitly defined peers. To exploit these vulnerabilities, the malicious BGP update message would need to come from a configured, valid BGP peer, or would need to be injected by the attacker into the victim's BGP network on an existing, valid TCP connection to a BGP peer.
