CVE-2020-12255 (GCVE-0-2020-12255)

Vulnerability from cvelistv5 – Published: 2020-05-18 14:05 – Updated: 2024-08-04 11:48

Summary

rConfig 3.9.4 is vulnerable to remote code execution due to improper validation in the file upload functionality. vendor.crud.php accepts a file upload by checking content-type without considering the file extension and header. Thus, an attacker can exploit this by uploading a .php file to vendor.php that contains arbitrary PHP code and changing the content-type to image/gif.

Severity

No CVSS data available.
