CVE-2025-49331 is a high-severity vulnerability classified under CWE-502: Deserialization of Untrusted Data, affecting the impleCode eCommerce Product Catalog up to version 3.4.3. This vulnerability arises when the application deserializes data from untrusted sources without proper validation or sanitization, enabling an attacker to perform object injection attacks. Object injection can lead to arbitrary code execution, privilege escalation, or other malicious actions depending on the application's context and the deserialized objects. The CVSS v3.1 base score is 7.2, indicating a high level of risk. The vector string (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) reveals that the attack can be performed remotely over the network with low attack complexity but requires high privileges (PR:H) and no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability, as successful exploitation can lead to full system compromise. No known exploits are currently reported in the wild, and no official patches or mitigations have been published yet. The vulnerability affects all versions up to 3.4.3, with no specific lower bound version identified (noted as 'n/a').

For European organizations using the impleCode eCommerce Product Catalog, this vulnerability poses a significant risk. Exploitation could allow attackers to execute arbitrary code on critical eCommerce infrastructure, potentially leading to data breaches involving customer personal and payment information, manipulation of product catalogs, disruption of online sales operations, and reputational damage. Given the high confidentiality, integrity, and availability impact, organizations could face regulatory penalties under GDPR if customer data is compromised. The requirement for high privileges to exploit suggests that attackers would need to gain some level of authenticated access first, which may limit the attack surface but does not eliminate risk, especially in environments with weak internal controls or compromised credentials. The lack of user interaction needed means automated attacks could be feasible once initial access is obtained. The absence of known exploits in the wild provides a window for proactive mitigation, but the high severity demands urgent attention.

Implement strict input validation and sanitization on all data deserialized by the eCommerce Product Catalog to prevent malicious object injection. Restrict deserialization to only trusted and verified sources, employing allowlists of acceptable classes or data formats where possible. Apply the principle of least privilege to service accounts and users interacting with the application to minimize the impact of compromised credentials. Monitor application logs and network traffic for unusual deserialization activity or anomalies indicative of exploitation attempts. Isolate the eCommerce Product Catalog environment using network segmentation and firewall rules to limit exposure to internal and external threats. Engage with impleCode vendor support channels to obtain patches or security advisories as they become available, and prioritize timely application of updates. Conduct regular security assessments and penetration tests focusing on deserialization vulnerabilities and privilege escalation vectors within the eCommerce platform. Implement multi-factor authentication (MFA) for all users with high privileges to reduce the risk of credential compromise leading to exploitation.
