A vulnerability in the Cisco Small Business Switches software could allow an unauthenticated, remote attacker to bypass the user authentication mechanism of an affected device. The vulnerability exists because under specific circumstances, the affected software enables a privileged user account without notifying administrators of the system. An attacker could exploit this vulnerability by using this account to log in to an affected device and execute commands with full admin rights.

Cisco has not released software updates that address this vulnerability. This advisory will be updated with fixed software information once fixed software becomes available. There is a workaround to address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181107-sbsw-privacc

Remedy

<p>The workaround consists of adding at least one user account with access privilege set to level 15 in the device configuration. The following example shows how to configure an account by using <em>admin</em> as user ID, setting the access privilege to level 15, and defining the password by replacing <strong_password> with a complex password chosen by the user. By adding this user account, the default privileged account will be disabled. </strong_password></p> <pre>Switch# configure terminal Switch(config)# username admin privilege 15 password <strong_password> </strong_password></pre> <p>The command <strong>show running-config | include privilege 15 </strong>will now produce the following output:</p> <blockquote> <pre>Switch# show running-config | include privilege 15 username admin password encrypted <encrypted-password> privilege 15</encrypted-password></pre> </blockquote>

A vulnerability in the web UI of Cisco Small Business Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper validation of requests sent to the web interface. An attacker could exploit this vulnerability by sending a malicious request to the web interface of an affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition. Cisco has released software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability.

A vulnerability in the web UI of Cisco Small Business Switches could allow an unauthenticated, remote attacker to access sensitive device information. The vulnerability exists because the software lacks proper authentication controls to information accessible from the web UI. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web UI of an affected device. A successful exploit could allow the attacker to access sensitive device information, which includes configuration files. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

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. There are no workarounds that address this vulnerability.
