Last modified

CVE-2025-20123 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. Multiple vulnerabilities in the web-based management interface of Cisco Crosswork Network Controller could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against users of the interface of an affected system. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by inserting malicious data into specific data fields in the interface. EPSS estimates a 0.26% chance of exploitation in the next 30 days.

Description

Multiple vulnerabilities in the web-based management interface of Cisco Crosswork Network Controller could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against users of the interface of an affected system. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by inserting malicious data into specific data fields in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit these vulnerabilities, the attacker must have valid administrative credentials. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
