CVE-2022-33077 is a high-severity access control vulnerability identified in nopCommerce version 4.50.2, an open-source e-commerce platform widely used for online retail solutions. This vulnerability allows unauthenticated attackers to arbitrarily modify any customer's address information via the 'addressedit' endpoint. The core issue stems from improper access control checks (classified under CWE-639: Authorization Bypass Through User-Controlled Key) that fail to verify whether the requesting user is authorized to edit the targeted customer's address. Consequently, an attacker can manipulate the address data of other customers without authentication or user interaction, leading to unauthorized data modification. The CVSS v3.1 score of 7.5 reflects the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), high integrity impact (I:H), and no availability impact (A:N). Although no known exploits are currently reported in the wild, the vulnerability presents a significant risk due to its ease of exploitation and potential for misuse. The lack of a vendor or product name in the provided data suggests the vulnerability is specific to nopCommerce 4.50.2, and organizations using this version should consider it critical to address. The vulnerability enables attackers to alter customer address data, which can facilitate fraudulent transactions, delivery interception, or further social engineering attacks, undermining customer trust and business operations.

For European organizations utilizing nopCommerce 4.50.2, this vulnerability poses a substantial risk to data integrity and customer trust. Unauthorized modification of customer addresses can lead to misdirected shipments, financial fraud, and potential regulatory non-compliance under GDPR due to unauthorized data manipulation. The integrity breach can disrupt order fulfillment processes, cause financial losses, and damage brand reputation. Additionally, attackers could leverage altered address data to facilitate identity theft or further phishing campaigns targeting affected customers. Given the e-commerce sector's critical role in Europe's digital economy, exploitation of this vulnerability could have cascading effects on supply chains and customer relations. The absence of confidentiality and availability impacts reduces the risk of data leakage or service downtime but does not diminish the serious consequences of integrity violations. Organizations in Europe must prioritize patching or mitigating this vulnerability to maintain compliance and operational security.

1. Immediate upgrade: Organizations should upgrade nopCommerce installations to a version where this vulnerability is patched. If an official patch is unavailable, consider applying community or vendor-provided workarounds. 2. Access control review: Conduct a thorough audit of access control mechanisms around customer data endpoints, ensuring strict authorization checks are enforced to prevent unauthorized modifications. 3. Endpoint hardening: Implement web application firewall (WAF) rules to monitor and block suspicious requests targeting the 'addressedit' endpoint, especially those attempting to modify addresses without proper authentication. 4. Logging and monitoring: Enhance logging of address modification activities and set up alerts for anomalous patterns, such as multiple address changes from a single IP or rapid successive edits. 5. Customer notification: Inform customers about the potential risk and encourage verification of their account details regularly. 6. Incident response readiness: Prepare to respond swiftly to any detected exploitation attempts, including isolating affected systems and conducting forensic analysis. 7. Principle of least privilege: Limit administrative and user privileges to only what is necessary, reducing the attack surface. 8. Security testing: Perform penetration testing focusing on access control vulnerabilities to identify and remediate similar issues proactively.
