CVE-2021-32760: Archive package allows chmod of file outside of unpack target directory

containerd is a container runtime. A bug was found in containerd versions prior to 1.4.8 and 1.5.4 where pulling and extracting a specially-crafted container image can result in Unix file permission changes for existing files in the host’s filesystem. Changes to file permissions can deny access to the expected owner of the file, widen access to others, or set extended bits like setuid, setgid, and sticky. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in containerd 1.5.4 and 1.4.8. As a workaround, ensure that users only pull images from trusted sources. Linux security modules (LSMs) like SELinux and AppArmor can limit the files potentially affected by this bug through policies and profiles that prevent containerd from interacting with specific files.

CVE-2021-1575: Cisco Virtualized Voice Browser Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Virtualized Voice Browser 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 an affected 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-2021-1574: Cisco Business Process Automation Privilege Escalation Vulnerabilities

Multiple vulnerabilities in the web-based management interface of Cisco Business Process Automation (BPA) could allow an authenticated, remote attacker to elevate privileges to Administrator. These vulnerabilities are due to improper authorization enforcement for specific features and for access to log files that contain confidential information. An attacker could exploit these vulnerabilities either by submitting crafted HTTP messages to an affected system and performing unauthorized actions with the privileges of an administrator, or by retrieving sensitive data from the logs and using it to impersonate a legitimate privileged user. A successful exploit could allow the attacker to elevate privileges to Administrator.

CVE-2021-1359: Cisco Web Security Appliance Privilege Escalation Vulnerability

A vulnerability in the configuration management of Cisco AsyncOS for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform command injection and elevate privileges to root. This vulnerability is due to insufficient validation of user-supplied XML input for the web interface. An attacker could exploit this vulnerability by uploading crafted XML configuration files that contain scripting code to a vulnerable device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root. An attacker would need a valid user account with the rights to upload configuration files to exploit this vulnerability.

CVE-2021-1562: Cisco BroadWorks Application Server Information Disclosure Vulnerability

A vulnerability in the XSI-Actions interface of Cisco BroadWorks Application Server could allow an authenticated, remote attacker to access sensitive information on an affected system. This vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the XSI-Actions interface. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to join a Call Center instance and have calls that they do not have permissions to access distributed to them from the Call Center queue. At the time of publication, Cisco had not released updates that address this vulnerability for Cisco BroadWorks Application Server. However, firmware patches are available.

CVE-2021-1595: Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities

Multiple vulnerabilities in the Link Layer Discovery Protocol (LLDP) implementation for Cisco Video Surveillance 7000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause a memory leak, which could lead to a denial of service (DoS) condition on an affected device. These vulnerabilities are due to incorrect processing of certain LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DoS condition. Note: LLDP is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
