CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3164 – Cisco ESA, Cisco WSA, and Cisco SMA GUI Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3164
A vulnerability in the web-based management interface of Cisco AsyncOS for Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA), and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of specific HTTP request headers. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to trigger a prolonged status of high CPU utilization relative to the GUI process(es). Upon successful exploitation of this vulnerability, an affected device will still be operative, but its response time and overall performance may be degraded. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cont-sec-gui-dos-nJ625dXb • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2019-1816 – Cisco Web Security Appliance Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1816
A vulnerability in the log subscription subsystem of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. The vulnerability is due to insufficient validation of user-supplied input on the web and command-line interface. An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root. Una vulnerabilidad en el subsistema de Subscripción de Registro (log subscription) de Cisco Web Security Appliance (WSA) podría permitir a un atacante local autorizado ejecutar la inyección de comandos y elevar los privilegios a root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-wsa-privesc • CWE-20: Improper Input Validation •
CVSS: 7.2EPSS: 0%CPEs: 4EXPL: 0CVE-2018-0428
https://notcve.org/view.php?id=CVE-2018-0428
A vulnerability in the account management subsystem of Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to elevate privileges to root. The attacker must authenticate with valid administrator credentials. The vulnerability is due to improper implementation of access controls. An attacker could exploit this vulnerability by authenticating to the device as a specific user to gain the information needed to elevate privileges to root in a separate login shell. A successful exploit could allow the attacker to escape the CLI subshell and execute system-level commands on the underlying operating system as root. • http://www.securityfocus.com/bid/105104 http://www.securitytracker.com/id/1041536 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180815-wsa-escalation • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •
