CVE-2020-27304 (GCVE-0-2020-27304)
Vulnerability from cvelistv5 – Published: 2021-10-21 15:42 – Updated: 2024-08-04 16:11
VLAI
Summary
The CivetWeb web library does not validate uploaded filepaths when running on an OS other than Windows, when using the built-in HTTP form-based file upload mechanism, via the mg_handle_form_request API. Web applications that use the file upload form handler, and use parts of the user-controlled filename in the output path, are susceptible to directory traversal
Severity
No CVSS data available.
