CVE-2018-11494: Opencart

High severity, CVSS 8.0. EPSS: 2.3% chance of exploitation in the next 30 days.

The "program extension upload" feature in OpenCart through 3.0.2.0 has a six-step process (upload, install, unzip, move, xml, remove) that allows attackers to execute arbitrary code if the remove step is skipped, because the attacker can discover a secret temporary directory name (containing 10 random digits) via a directory traversal attack involving language_info['code'].

Affected products

• Opencart Opencart: up to and including 3.0.2.0
