CVE-2026-20232: 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.

Event History
Frequently Asked Questions
Who is exposed to this vulnerability?
Users of the web-based management interface on affected Cisco Industrial Ethernet 1000 Series Switches are exposed if they view interface pages containing attacker-supplied malicious code. The attacker must already hold valid credentials for the affected system.
Does exploitation require user interaction?
Yes. Exploitation requires a user of the web-based management interface to encounter the stored malicious content. The attacker can then execute script code in that user's interface context.
What level of access does an attacker need?
The attacker needs valid user credentials on the affected switch and can exploit the issue remotely through its web-based management interface.
