CVE-2020-27870Public exploitNetwork attack vector

File disclosure via unvalidated PDF references

Published Feb 10, 2021 · Updated Aug 4, 2024

Path traversal in ExportToPDF.aspx in SolarWinds Orion Platform 2020.2.1 allows remote authenticated users to read local files. The PDF converter accepts attacker-supplied HTML with local-file references and embeds those files in the generated PDF without validating the paths. Access to the endpoint is required; a disabled-by-default guest account can reach it when enabled, exposing files readable as SYSTEM.
