cisco-sa-ie1k-NgXUFF52: Cisco Industrial Ethernet 1000 Series Switches Stored Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco Industrial Ethernet (IE) 1000 Series Switches could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface.This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of another user. To exploit this vulnerability, the attacker must have valid user credentials on the affected system.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-ie1k-NgXUFF52
Event History
Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must be remote and authenticated to the switch's web-based management interface with valid user credentials. The attack is relevant where other users also access that interface, because the injected script executes in another user's browser context.
What should administrators do if they cannot patch immediately?
No workaround is available. Administrators should apply the Cisco software updates that address the issue; until then, restrict access to the web-based management interface to trusted, authenticated users and limit exposure to untrusted networks.
How can an organization determine whether it may be affected?
Review whether Cisco Industrial Ethernet 1000 Series Switches are deployed and whether their web-based management interfaces are enabled and used. Systems that allow authenticated users to submit input through the interface may be exposed to stored script injection.
