CVE-2023-5950: 
Velociraptor vulnerability analysis and mitigation

Rapid7 Velociraptor versions prior to 0.7.0-4 suffer from a reflected cross site scripting vulnerability (CVE-2023-5950). The vulnerability was discovered through a security code review and was disclosed on November 6, 2023. This issue affects the server component of Velociraptor, allowing attackers to inject JavaScript into the error path (Rapid7 Blog).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). It has received a CVSS v3.1 score of 8.6 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L. The vulnerability allows attackers to inject JavaScript code into the error path, which can lead to unauthorized execution of scripts within a user's web browser (NVD).

The successful exploitation of this vulnerability could potentially lead to unauthorized execution of scripts within a user's web browser. This could result in compromised confidentiality through information disclosure, and limited impact on integrity and availability of the affected system (Rapid7 Blog).

To remediate this vulnerability, users should upgrade their Velociraptor servers to version 0.7.0-4 or later. For those running version 0.6.9, patches are available in version 0.6.9-1 (Rapid7 Blog).

The vulnerability was responsibly disclosed and addressed through coordinated efforts between the security researcher Mathias Kujala and the Velociraptor team. The vendor promptly released patches and provided clear upgrade instructions to affected users (Release Notes).
