CVE-2023-20197: Cisco Security Advisory: ClamAV HFS+ File Scanning Infinite Loop Denial of Service Vulnerability

A vulnerability in the filesystem image parser for Hierarchical File System Plus (HFS+) of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an incorrect check for completion when a file is decompressed, which may result in a loop condition that could cause the affected software to stop responding. An attacker could exploit this vulnerability by submitting a crafted HFS+ filesystem image to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to stop responding, resulting in a DoS condition on the affected software and consuming available system resources. For a description of this vulnerability, see the ClamAV blog .

CVE-2023-20224: Cisco Security Advisory: Cisco ThousandEyes Enterprise Agent Virtual Appliance Privilege Escalation Vulnerability

A vulnerability in the CLI of Cisco ThousandEyes Enterprise Agent, Virtual Appliance installation type, could allow an authenticated, local attacker to elevate privileges to root on an affected device. This vulnerability is due to insufficient input validation of user-supplied CLI arguments. An attacker could exploit this vulnerability by authenticating to an affected device and using crafted commands at the prompt. A successful exploit could allow the attacker to execute arbitrary commands as root. The attacker must have valid credentials on the affected device.

CVE-2023-20217: Cisco Security Advisory: Cisco ThousandEyes Enterprise Agent Virtual Appliance Privilege Escalation Vulnerability

A vulnerability in the CLI of Cisco ThousandEyes Enterprise Agent, Virtual Appliance installation type, could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to insufficient input validation by the operating system CLI. An attacker could exploit this vulnerability by issuing certain commands using sudo. A successful exploit could allow the attacker to view arbitrary files as root on the underlying operating system. The attacker must have valid credentials on the affected device.

CVE-2023-20228: Cisco Security Advisory: Cisco Integrated Management Controller Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.

CVE-2023-20242: Cisco Security Advisory: Cisco Unified Communications Products Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM), Cisco Unified CM Session Management Edition (Unified CM SME), and Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted 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.

CVE-2023-20209: Cisco Security Advisory: Cisco Expressway Series and Cisco TelePresence Video Communication Server Command Injection Vulnerability

A vulnerability in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker with read-write privileges on the application to perform a command injection attack that could result in remote code execution on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface of an affected device. A successful exploit could allow the attacker to establish a remote shell with root privileges.
