Lifecycle Timeline
2DescriptionCVE.org
Multiple vulnerabilities in the web-based management interface of Cisco Packaged Contact Center Enterprise (Packaged CCE) and Cisco Unified Contact Center Enterprise (Unified CCE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.
These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities 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 the affected interface or access sensitive, browser-based information. To exploit these vulnerabilities, the attacker must have valid administrative credentials.
AnalysisAI
Stored XSS vulnerabilities in Cisco Packaged CCE and Unified CCE web management interfaces allow authenticated attackers to inject malicious scripts that execute in the context of other users' browsers, potentially enabling session hijacking or sensitive data theft. The vulnerability stems from inadequate input validation on specific interface pages and requires high-privilege account access and user interaction to exploit. No patch is currently available for this medium-severity issue (CVSS 4.8).
