Summary
Cisco Small Business 220 Series Smart Switches Command Injection Vulnerability
Notes
Summary
A vulnerability in the web management interface of Cisco Small Business 220 Series Smart Switches could allow an authenticated, remote attacker to perform a command injection attack.
The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious request to certain parts of the web management interface. To send the malicious request, the attacker needs a valid login session in the web management interface as a privilege level 15 user. Depending on the configuration of the affected switch, the malicious request must be sent via HTTP or HTTPS. A successful exploit could allow the attacker to execute arbitrary shell commands with the privileges of the root user.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
This advisory is available at the following link:
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190806-sb220-inject ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190806-sb220-inject"]
Vulnerable Products
At the time of publication, this vulnerability affected Cisco Small Business 220 Series Smart Switches running firmware versions prior to 1.1.4.4 with the web management interface enabled. The web management interface is enabled via both HTTP and HTTPS by default.
See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
Determining Whether the Web Management Interface Is Enabled
To determine whether the web management interface is enabled via either HTTP or HTTPS, administrators can use the show running-config command on the device CLI. If both of the following lines are present in the configuration, the web management interface is disabled and the device is not vulnerable:
no ip http server
no ip http secure server
Any other output indicates that the web management interface is enabled on the device.
In the web management interface, the HTTP Service and HTTPS Service are configured under Security > TCP/UDP Service.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability.
Workarounds
There are no workarounds that address this vulnerability.
Fixed Software
When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
Fixed Releases
At the time of publication, Cisco 220 Series Switches firmware releases 1.1.4.4 and later contained the fix for this vulnerability.
See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
