Technical details
A path traversal vulnerability (CWE-22) exists in the Regular Labs GeoIP extension for Joomla versions 1.0.0 through 6.3.8. The issue stems from the broad extraction of Geo IP database update archives without sufficient validation of the file paths contained within the archive. An attacker who can influence the source or content of the database update archive could potentially write arbitrary files to the server's filesystem. This could lead to remote code execution if the attacker is able to overwrite executable files or place new scripts in web-accessible directories.
