IMPORTANT NOTICE: DO NOT REPORT VULNERABILITIES SOLELY TO THE AUTHOR OR MARKETPLACE.
We urge you to report any vulnerabilities directly to us. Our mission is to ensure the safety and security of the PrestaShop ecosystem. Unfortunately, many module developers may not always recognize or acknowledge the vulnerabilities in their code, whether due to lack of awareness, or inability to properly evaluate the associated risk, or other reasons.
Given the rise in professional cybercrime networks actively seeking out these vulnerabilities, it's crucial that any potential threats are promptly addressed and the community is informed. The most effective method to do this is by publishing a CVE, like the one provided below.
Should you discover any vulnerabilities, please report them to us at: report[@]security-presta.org or visit https://security-presta.org for more information.
Every vulnerability report helps make the community more secure, and we are profoundly grateful for any information shared with us.
[CVE-2023-39677] PHPInfo Exposure in MyPrestaModules SimpleImportProduct and UpdateProducts Modules
MyPrestaModules SimpleImportProduct Prestashop Module v6.2.9 and UpdateProducts Prestashop Module v3.6.9 were discovered to contain a PHPInfo information disclosure vulnerability via send.php.
Summary
- CVE ID: CVE-2023-39677
- Published at: 2023-09-07
- Discovery credit: Sorcery
- Platform: PrestaShop
- Product: SimpleImportProduct / UpdateProducts
- Impacted release: < 6.4.0 / < v3.8.1
- Product author: MyPrestaModules
- Weakness: CWE-200
- Severity: medium (5.3)
Description
Two modules that we tested by MyPrestaModules have a vulnerability where PHPInfo is exposed to an unauthenticated attacker. The modules SimpleImportProduct and UpdateProducts contain a file called send.php that has the following code snippet:
if ( Tools::getValue('phpinfo') ){
phpinfo();
die;
}
This exposes PHPInfo information which could be a little [EDIT FOP] useful to an attacker and it requires no authentication to exploit. This was reported to MyPrestaModules and a patch was released.
