This vulnerability allows ps_contactinfo, a PrestaShop module for displaying store contact information, to become vulnerable to cross-site scripting (XSS) attacks in versions up to and including 3.3.2. It is crucial to note that this vulnerability cannot be exploited in a fresh installation of PrestaShop; it specifically affects shops that have been made vulnerable by third-party modules. For instance, if a shop uses a third-party module that is susceptible to SQL injections, then ps_contactinfo might execute a stored XSS in formatting objects.
The recent commit, d60f9a5634b4fc2d3a8831fb08fe2e1f23cbfa39, addresses this issue by preventing formatted addresses from displaying an XSS stored in the database. The fix is anticipated to be available in version 3.3.3. Organizations are advised that no workarounds exist aside from applying this fix and ensuring that all modules are maintained and updated.
The vulnerability has a CVSS score of 6.2, which classifies it as medium severity. This indicates a moderate risk to organizations, particularly those that have third-party modules integrated into their systems. The vulnerability's exploitation status is currently deferred, meaning that it’s important for organizations to stay updated on any forthcoming patches.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. Keeping all modules up to date is essential in preventing potential exploitation through XSS vulnerabilities.
Vulnerability Details
The ps_contactinfo module has been identified with a cross-site scripting (XSS) vulnerability that affects versions up to and including 3.3.2. The official description highlights that this vulnerability can be exploited when the shop has third-party modules that introduce vulnerabilities. The CVSS score of this vulnerability is 6.2, indicating a medium severity due to the potential for significant confidentiality impact, low integrity impact, and high availability impact.
This vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation (cross-site scripting). Affected systems include all installations of the ps_contactinfo module prior to the fix in version 3.3.3, with no specific vendor or product details available.
Technical Analysis
The root cause of this vulnerability lies in the handling of user input within the ps_contactinfo module. When third-party modules introduce vulnerabilities, such as SQL injection, the ps_contactinfo module can inadvertently execute stored XSS, which may lead to unauthorized access to sensitive data or session hijacking.
The attack vector for this vulnerability is network-based, meaning that an attacker could exploit it remotely through the network. The attack complexity is classified as high, requiring a significant level of privileges to execute the attack. Specifically, high privileges are required to trigger the condition that leads to the XSS vulnerability, and no user interaction is necessary for the attack to succeed.
Confidentiality impact is assessed as high, as successful exploitation could lead to unauthorized access to sensitive user data. Integrity impact is low, meaning that while data may be exposed, it is not subject to alteration through this vulnerability. Availability impact is high, indicating that this vulnerability could potentially disrupt service availability.
Risk & Impact Analysis
Risk to organizations includes the potential for data breaches and unauthorized access to user information through XSS exploitation. The blast radius is significant, particularly for organizations using multiple third-party modules that might introduce additional vulnerabilities. Given the medium severity score of 6.2, organizations should assess the urgency of addressing this vulnerability within their patch management cycle.
Organizations should address in priority patch cycle, especially those operating e-commerce platforms or utilizing sensitive customer data. The lack of immediate workarounds emphasizes the necessity for swift action to mitigate this vulnerability.

Affected Versions
All versions prior to vendor patch, specifically versions up to and including 3.3.2 of the ps_contactinfo module. Organizations should ensure that they upgrade to version 3.3.3 or later to mitigate this vulnerability.
Mitigation & Remediation
Organizations should apply the fix available in version 3.3.3 of the ps_contactinfo module as soon as it is released. Regularly maintaining and updating all third-party modules is critical to preventing vulnerabilities. Additionally, organizations should implement proper security controls and monitoring to detect any attempts to exploit such vulnerabilities.
For further assistance, organizations can consider utilizing penetration testing services to identify and remediate similar vulnerabilities in their systems.
Detection Guidance
Organizations should monitor logs for indicators of XSS attacks, such as unusual input patterns in user-generated content. Behavioral anomalies, such as unexpected redirects or unauthorized content display, should also be tracked. Additionally, network signatures associated with XSS attempts can provide valuable detection capabilities.
