CVE-2020-20907Network attack vector

Arbitrary ini file modification and deletion

Published May 24, 2021 · Updated Aug 4, 2024

File modification in MetInfo 7.0 beta allows remote attackers to delete and modify ini files via vulnerable language and file-function components. The language_general.class.php and file.func.php components perform file operations that permit alteration or removal of ini files. Network reachability and unauthenticated access are indicated by NVD scoring, while configuration preconditions are undocumented; impact is integrity loss with possible service disruption.
