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.
The severity of this vulnerability is classified as medium with a CVSS score of 4.8. This level of severity indicates a moderate risk to organizations, particularly those using the affected Cisco applications. The attack vector is network-based, and the complexity of the attack is low, making it easier for attackers to exploit these vulnerabilities if they possess the necessary administrative credentials.
Currently, there is no public exploit confirmed for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant, as the potential for exploitation exists due to the nature of the vulnerabilities.
Organizations should prioritize patching immediately to mitigate the risks associated with these vulnerabilities. Ensuring that administrative credentials are managed securely and that user input is properly validated are critical steps in reducing the potential attack surface.
Vulnerability Details
The vulnerabilities in question are classified under CWE-79, which pertains to improper neutralization of input during web page generation (XSS). This means that the web application fails to sanitize user input, allowing attackers to inject malicious scripts that can be executed in the browser of the victim.
Cisco published the advisory detailing these vulnerabilities on January 21, 2026. Organizations utilizing Cisco Packaged CCE or Unified CCE should take immediate action to address this issue.
Technical Analysis
The root cause of these vulnerabilities lies in the failure to properly validate user input in the web-based management interface. Attackers can leverage this weakness to conduct XSS attacks, which may result in the execution of arbitrary script code or unauthorized access to sensitive data.
The attack vector is network-based, which means that the attacker does not need physical access to the device to exploit the vulnerability. The attack complexity is low, indicating that the attacker needs minimal skill to perform the exploit. Additionally, high privileges are required, as the attacker must possess administrative credentials to successfully execute the attack.
User interaction is required, as the victim must access the affected web management interface for the attack to succeed. The impact on confidentiality and integrity is classified as low, while there is no impact on availability.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information and execution of malicious scripts in user contexts. The blast radius could extend to any user accessing the affected management interface, making it critical for organizations to address this vulnerability swiftly.
Urgency for defenders is medium, as the exploitation requires specific conditions to be met, including valid administrative credentials. However, organizations should not underestimate the risk of XSS attacks and must take necessary precautions.
