Cisco Intersight Virtual Appliance

A vulnerability in the read-only maintenance shell of Cisco Intersight Virtual Appliance could
CVE-2026-20092 6 - Medium - January 21, 2026

A vulnerability in the read-only maintenance shell of Cisco Intersight Virtual Appliance could allow an authenticated, local attacker with administrative privileges to elevate privileges to root on the virtual appliance. This vulnerability is due to improper file permissions on configuration files for system accounts within the maintenance shell of the virtual appliance. An attacker could exploit this vulnerability by accessing the maintenance shell as a read-only administrator and manipulating system files to grant root privileges. A successful exploit could allow the attacker to elevate their privileges to root on the virtual appliance and gain full control of the appliance, giving them the ability to access sensitive information, modify workloads and configurations on the host system, and cause a denial of service (DoS).

Incorrect Permission Assignment for Critical Resource

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2
CVE-2021-44228 10 - Critical - December 10, 2021

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

Marshaling, Unmarshaling

A vulnerability in the web-based management interface of Cisco Intersight Virtual Appliance could
CVE-2021-34748 8.8 - High - October 06, 2021

A vulnerability in the web-based management interface of Cisco Intersight Virtual Appliance could allow an authenticated, remote attacker to perform a command injection attack on an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by using the web-based management interface to execute a command using crafted input. A successful exploit could allow the attacker to execute arbitrary commands using root-level privileges on an affected device.

Shell injection

Multiple vulnerabilities in the web-based management interface of Cisco Intersight Virtual Appliance could
CVE-2021-1618 7.2 - High - July 22, 2021

Multiple vulnerabilities in the web-based management interface of Cisco Intersight Virtual Appliance could allow an authenticated, remote attacker to conduct a path traversal or command injection attack on an affected system. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by using the web-based management interface to do one or both of the following: Execute a command using crafted input Upload a file that has been altered using path traversal techniques A successful exploit could allow the attacker to read and write arbitrary files or execute arbitrary commands as root on an affected system. For more information about these vulnerabilities, see the Details section of this advisory.

Shell injection

Multiple vulnerabilities in the web-based management interface of Cisco Intersight Virtual Appliance could
CVE-2021-1617 6.5 - Medium - July 22, 2021

Multiple vulnerabilities in the web-based management interface of Cisco Intersight Virtual Appliance could allow an authenticated, remote attacker to conduct a path traversal or command injection attack on an affected system. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by using the web-based management interface to do one or both of the following: Execute a command using crafted input Upload a file that has been altered using path traversal techniques A successful exploit could allow the attacker to read and write arbitrary files or execute arbitrary commands as root on an affected system. For more information about these vulnerabilities, see the Details section of this advisory.

Directory traversal

Multiple vulnerabilities in Cisco Intersight Virtual Appliance could
CVE-2021-1600 8.3 - High - July 22, 2021

Multiple vulnerabilities in Cisco Intersight Virtual Appliance could allow an unauthenticated, adjacent attacker to access sensitive internal services from an external interface. These vulnerabilities are due to insufficient restrictions for IPv4 or IPv6 packets that are received on the external management interface. An attacker could exploit these vulnerabilities by sending specific traffic to this interface on an affected device. A successful exploit could allow the attacker to access sensitive internal services and make configuration changes on the affected device.

Multiple vulnerabilities in Cisco Intersight Virtual Appliance could
CVE-2021-1601 8.3 - High - July 22, 2021

Multiple vulnerabilities in Cisco Intersight Virtual Appliance could allow an unauthenticated, adjacent attacker to access sensitive internal services from an external interface. These vulnerabilities are due to insufficient restrictions for IPv4 or IPv6 packets that are received on the external management interface. An attacker could exploit these vulnerabilities by sending specific traffic to this interface on an affected device. A successful exploit could allow the attacker to access sensitive internal services and make configuration changes on the affected device.
