A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.
With a CVSS score of 4.8, this vulnerability is classified as medium severity. Organizations using Cisco IMC should be aware of the potential risks associated with this vulnerability, including unauthorized access to sensitive information via stored XSS attacks. As the vulnerability is currently in an 'Awaiting Analysis' status, organizations should remain vigilant and prepared to apply updates or mitigations as they become available.
The urgency for defenders is moderate, given the potential impact of this vulnerability. Organizations should schedule remediation as part of their vulnerability management program.
Monitoring for signs of exploitation and ensuring that users are aware of phishing attempts that could leverage this vulnerability is also recommended.
Vulnerability Details
A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with administrative privileges to conduct a stored XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.
The CVSS score for this vulnerability is 4.8, indicating a medium severity level. This score reflects a network attack vector, low attack complexity, high privileges required, and user interaction required for successful exploitation. The impacts on confidentiality and integrity are rated as low, while availability is rated as none.
The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation (Cross-site Scripting).
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of user input within the Cisco IMC web-based management interface. Attackers can exploit this vulnerability by convincing users to interact with malicious links, triggering the execution of arbitrary scripts within their browsers.
The attack vector is primarily network-based, with low complexity for exploitation. High privileges are necessary for an attacker to initiate a successful attack, and user interaction is required to complete the exploitation process. The vulnerability poses a low risk to confidentiality and integrity but does not affect availability.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive information and the execution of arbitrary script code in user browsers. The blast radius for this vulnerability is significant if exploited, as it affects any authenticated user interacting with the web interface.
Organizations should prioritize their response to this vulnerability, ensuring that administrative users are aware of the risks and monitoring for suspicious activity. Given the CVSS score of 4.8 and the ongoing analysis status, organizations should schedule remediation as part of their regular patch management processes.
