CVE-2011-4544 in Prestashop
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in Prestashop before 1.5 allow remote attackers to inject arbitrary web script or HTML via the (1) address or (2) relativ_base_dir parameter to modules/mondialrelay/googlemap.php; the (3) relativ_base_dir, (4) Pays, (5) Ville, (6) CP, (7) Poids, (8) Action, or (9) num parameter to prestashop/modules/mondialrelay/googlemap.php; (10) the num_mode parameter to modules/mondialrelay/kit_mondialrelay/RechercheDetailPointRelais_ajax.php; (11) the Expedition parameter to modules/mondialrelay/kit_mondialrelay/SuiviExpedition_ajax.php; or the (12) folder or (13) name parameter to admin/ajaxfilemanager/ajax_save_text.php.

The CVE-2011-4544 vulnerability represents a critical cross-site scripting vulnerability affecting PrestaShop versions prior to 1.5, exposing multiple attack vectors through various module components. This vulnerability falls under CWE-79 which specifically addresses cross-site scripting flaws in web applications. The flaw stems from inadequate input validation and output encoding mechanisms within the mondialrelay module and the admin file manager component, creating persistent XSS attack surfaces that can be exploited by remote attackers to inject malicious scripts into web pages viewed by other users.
The technical exploitation occurs through multiple parameters across different PHP files within the PrestaShop ecosystem. Attackers can manipulate the address and relativ_base_dir parameters in the googlemap.php module to inject malicious scripts, while additional vulnerable parameters include relativ_base_dir, Pays, Ville, CP, Poids, Action, and num in the same module file. The attack surface expands to include the num_mode parameter in RechercheDetailPointRelais_ajax.php and the Expedition parameter in SuiviExpedition_ajax.php, while also encompassing folder and name parameters in the admin/ajaxfilemanager/ajax_save_text.php file. These multiple entry points indicate a systemic lack of proper input sanitization across the affected modules.
The operational impact of this vulnerability is significant as it allows attackers to execute arbitrary web scripts in the context of affected users' browsers, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The attack vectors span across different functional areas including shipping module integration, point of service tracking, and administrative file management, making the exploitation scenario more versatile and dangerous. Users with administrative privileges face heightened risk as the vulnerability could potentially be leveraged to gain full control over the e-commerce platform.
Mitigation strategies should focus on immediate patching of the PrestaShop platform to version 1.5 or later where the XSS vulnerabilities have been addressed. Organizations should implement comprehensive input validation and output encoding mechanisms across all user-supplied data, particularly in module components that handle external inputs. The implementation of Content Security Policy (CSP) headers can provide additional defense-in-depth measures to prevent script execution from unauthorized sources. Regular security audits of third-party modules and adherence to secure coding practices as outlined in OWASP Top Ten and NIST guidelines should be enforced to prevent similar vulnerabilities in future deployments. The vulnerability also highlights the importance of proper parameter validation and the need for consistent security measures across all application components rather than relying solely on perimeter defenses.
