- Product: exportproducts
- Impacted release: <= 4.1.1 (5.0.0 fixed the vulnerability)
- Product author: MyPrestaModules

WARNING : Be informed that this vulnerability is exploited.
CVSS base metrics
- Attack vector: network
- Attack complexity: low
- Privilege required: none
- User interaction: none
- Scope: unchanged
- Confidentiality: high
- Integrity: none
- Availability: none
Vector string: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Possible malicious usage
- Stealing secrets to unlock admin controllers based on ajax script
- Exfiltrate all modules with all versions to facilitate pentesting
- Stealing table_prefix to greatly facilitate SQL injections for kiddies who don’t know how to exploit DBMS design’s vulnerabilities or steal database access to login in exposed PHPMyAdmin/Adminer/etc.
- Bypass WAF / htaccess restrictions to read forbidden files (such as logs on predictable paths of banks’s modules inside /var/log/)
Proof of concept
curl -v -d 'url=../../config/settings.inc.php' 'https://preprod.X/modules/exportproducts/download.php'
Patch from 4.1.1
The file has been comptely rewritten on 5.0.0.
--- a/modules/exportproducts/download.php +++ b/modules/exportproducts/download.php -$file = Tools::getValue('url'); +$file = basename(Tools::getValue('url'));
- It’s recommended to upgrade to the latest version of the module exportproducts.
- You should consider restricting the access of modules/exportproducts/ to a whitelist
- NEVER expose a PHPMyAdmin / Adminer / etc without, at least, a htpasswd
- Activate OWASP 930’s rules on your WAF (Web application firewall) and adjust it for your PrestaShop
