The vulnerability identified as CVE-2023-6184 is a Cross Site Scripting vulnerability in Citrix Session Recording that allows attackers to perform Cross Site Scripting attacks. Given the medium severity level with a CVSS score of 5, organizations must recognize the potential risks associated with this vulnerability. The medium score indicates that exploitation is possible but may require a higher level of privileges or specific conditions.
Risk to organizations includes the potential for attackers to execute arbitrary scripts in the context of a user’s browser, which could lead to data theft or unauthorized actions. As of now, there are no known exploits for this vulnerability, but organizations should remain vigilant and prioritize mitigation efforts.
Organizations should prioritize patching immediately. With a CVSS score of 5, it is essential to address this vulnerability during the next patch cycle to maintain the security posture and protect sensitive information.
This vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-913 (Improper Control of Document Type). It affects several versions of Citrix Virtual Apps and Desktops, specifically versions up to 2311 and various cu versions of 1912 and 2203.
Given the attack vector is network-based and the attack complexity is high, organizations should ensure that their configurations are hardened. Regular updates and monitoring for unusual activity can help mitigate the risks associated with this vulnerability.
Vulnerability Details
The official description of CVE-2023-6184 states that it is a Cross Site Scripting vulnerability in Citrix Session Recording, allowing attackers to perform Cross Site Scripting. This vulnerability is classified with a CVSS score of 5, indicating medium severity.
The vulnerability affects the Citrix Virtual Apps and Desktops product, with the publication date of January 18, 2024. The CWE classifications associated with this vulnerability are CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-913 (Improper Control of Document Type).
Technical Analysis
