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: 5.8EPSS: 0%CPEs: 3EXPL: 0CVE-2019-1672 – Cisco Web Security Appliance Decryption Policy Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1672
A vulnerability in the Decryption Policy Default Action functionality of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured drop policy and allow traffic onto the network that should have been denied. The vulnerability is due to the incorrect handling of SSL-encrypted traffic when Decrypt for End-User Notification is disabled in the configuration. An attacker could exploit this vulnerability by sending a SSL connection through the affected device. A successful exploit could allow the attacker to bypass a configured drop policy to block specific SSL connections. Releases 10.1.x and 10.5.x are affected. • http://www.securityfocus.com/bid/106904 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190206-wsa-bypass • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2018-0410
A vulnerability in the web proxy functionality of Cisco AsyncOS Software for Cisco Web Security Appliances could allow an unauthenticated, remote attacker to exhaust system memory and cause a denial of service (DoS) condition on an affected system. The vulnerability exists because the affected software improperly manages memory resources for TCP connections to a targeted device. An attacker could exploit this vulnerability by establishing a high number of TCP connections to the data interface of an affected device via IPv4 or IPv6. A successful exploit could allow the attacker to exhaust system memory, which could cause the system to stop processing new connections and result in a DoS condition. System recovery may require manual intervention. • http://www.securityfocus.com/bid/105098 http://www.securitytracker.com/id/1041535 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180815-wsa-dos • CWE-400: Uncontrolled Resource Consumption •

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 •

https://notcve.org/view.php?id=CVE-2018-0406
A vulnerability in the web-based management interface of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to conduct a reflected or Document Object Model based (DOM-based) cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. 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 interface or allow the attacker to access sensitive browser-based information.
