JavaScript vulnerability analysis and mitigation
Overview
CVE-2020-8902 affects Rendertron versions prior to 3.0.0, where the software is susceptible to a Server-Side Request Forgery (SSRF) attack. The vulnerability was disclosed and patched with the release of Rendertron version 3.0.0 (Rendertron Release).
Technical details
The vulnerability allows an attacker to use a specially crafted webpage to force a rendertron headless chrome process to render internal sites it has access to and display it as a screenshot. The vulnerability has been assigned a CVSS v3.1 base score of 4.3 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N. The weakness is categorized as CWE-918 (Server-Side Request Forgery) (NVD).
Impact
The vulnerability could allow attackers to access and capture screenshots of internal sites that the rendertron headless chrome process has access to, potentially exposing sensitive internal information (NVD).
Mitigation and workarounds
The recommended mitigation is to upgrade Rendertron to version 3.0.0 or later. If updating is not possible, users should secure their infrastructure to limit the headless chrome's access to internal domains (Rendertron Release).
