A vulnerability in the web-based interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface of the affected service. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected service. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted link. 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.
The severity of this vulnerability is classified as medium, with a CVSS score of 6.1. This indicates a moderate risk, primarily due to the nature of the attack vector and the potential impact on user data. Organizations should be aware that the exploitation of this vulnerability could lead to unauthorized access to sensitive information.
Currently, there is no confirmed public exploit available for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, given the nature of XSS vulnerabilities, the risk remains significant, especially for organizations that rely heavily on web-based interfaces.
Organizations should prioritize patching immediately to mitigate this risk. Ensuring user awareness about the potential for such attacks and implementing security measures to validate user input can help reduce exposure.
Vulnerability Details
The vulnerability in Cisco Webex Meetings allows attackers to perform cross-site scripting attacks through insufficient validation of user input. The CVSS score of 6.1 indicates a medium severity level, with low attack complexity and no required privileges to exploit. The vulnerability affects version 41.1.0 of Cisco Webex Meetings.
Technical Analysis
The root cause of this vulnerability lies in the web-based interface's failure to properly validate user inputs. Attackers may leverage this weakness to execute arbitrary scripts in the context of the user's session. The attack vector is network-based, requiring user interaction through clicking a malicious link.
The attack complexity is low, as it does not require any advanced skills or privileges. User interaction is required for successful exploitation, as the attacker must convince the user to click the malicious link. The impact on confidentiality and integrity is rated as low, while availability is not affected.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive information and user sessions. The blast radius could extend to all users of the affected service, emphasizing the need for swift action. Given the medium severity rating, organizations should address this vulnerability in their priority patch cycle.
