CVE-2020-3297 – Cisco Small Business Smart and Managed Switches Session Management Vulnerability
https://notcve.org/view.php?id=CVE-2020-3297
A vulnerability in session management for the web-based interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to defeat authentication protections and gain unauthorized access to the management interface. The attacker could obtain the privileges of the highjacked session account, which could include administrator privileges on the device. The vulnerability is due to the use of weak entropy generation for session identifier values. An attacker could exploit this vulnerability to determine a current session identifier through brute force and reuse that session identifier to take over an ongoing session. In this way, an attacker could take actions within the management interface with privileges up to the level of the administrative user. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sbswitch-session-JZAS5jnY • CWE-287: Improper Authentication •
CVE-2019-12718 – Cisco Small Business Smart and Managed Switches Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2019-12718
A vulnerability in the web-based interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link and subsequently access a specific web interface page. 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. Una vulnerabilidad en la interfaz basada en web de Cisco Small Business Smart and Managed Switches, podría permitir a un atacante remoto no autenticado conducir un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz basada en web. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-sbss-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2019-12636 – Cisco Small Business Smart and Managed Switches Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2019-12636
A vulnerability in the web-based management interface of Cisco Small Business Smart and Managed Switches could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. If the user has administrative privileges, the attacker could alter the configuration, execute commands, or cause a denial of service (DoS) condition on an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191016-sbss-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
CVE-2019-1943 – Cisco Small Business Series Switches Open Redirect Vulnerability
https://notcve.org/view.php?id=CVE-2019-1943
A vulnerability in the web interface of Cisco Small Business 200, 300, and 500 Series Switches software could allow an unauthenticated, remote attacker to redirect a user to a malicious web page. The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user's HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites. Una vulnerabilidad en la interfaz web del software Cisco Small Business 200, 300 y 500 Series Switches podría permitir que un atacante remoto no autenticado redirija a un usuario a una página web maliciosa. • https://www.exploit-db.com/exploits/47118 http://www.securityfocus.com/bid/109288 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190717-sbss-redirect • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVE-2019-1859 – Cisco Small Business Switches Secure Shell Certificate Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1859
A vulnerability in the Secure Shell (SSH) authentication process of Cisco Small Business Switches software could allow an attacker to bypass client-side certificate authentication and revert to password authentication. The vulnerability exists because OpenSSH mishandles the authentication process. An attacker could exploit this vulnerability by attempting to connect to the device via SSH. A successful exploit could allow the attacker to access the configuration as an administrative user if the default credentials are not changed. There are no workarounds available; however, if client-side certificate authentication is enabled, disable it and use strong password authentication. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-scbv • CWE-285: Improper Authorization CWE-295: Improper Certificate Validation •
