CVE-2026-20232
MediumCVSS 5.4Summary
A vulnerability in the web-based management interface of Cisco Industrial Ethernet 1000 Series Switches allows an authenticated remote attacker to perform a stored XSS attack. The issue is due to insufficient input validation, enabling injection of malicious code into interface pages.
Risk Assessment
An attacker can execute arbitrary script in another user's context, potentially leading to session theft, configuration changes, or further attacks within the interface.
Recommendation
Apply vendor updates, restrict access to the management interface, and regularly audit user permissions.
Original NVD description (English source)
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.
