CVE-2025-52828 is a high-severity vulnerability classified under CWE-502, which pertains to the deserialization of untrusted data. This vulnerability affects the designthemes product 'Red Art' up to version 3.7. Deserialization vulnerabilities occur when an application deserializes data from untrusted sources without sufficient validation or sanitization, allowing attackers to manipulate serialized objects. In this case, the flaw enables object injection, which can lead to remote code execution, privilege escalation, or other malicious activities depending on the application's context and the deserialized objects. The CVSS 3.1 base score of 8.8 reflects a high impact, with network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). The vulnerability does not currently have known exploits in the wild, but the potential for severe damage is significant given the nature of object injection attacks. The absence of a patch link suggests that a fix may not yet be publicly available or is pending release. Organizations using Red Art versions up to 3.7 should consider this vulnerability critical to address promptly.

For European organizations, the impact of CVE-2025-52828 could be substantial, especially for those relying on the Red Art product for web design or content management purposes. Successful exploitation could lead to full system compromise, data breaches involving sensitive customer or business information, disruption of services, and potential lateral movement within corporate networks. Given the high confidentiality, integrity, and availability impacts, affected organizations might face regulatory consequences under GDPR if personal data is compromised. Additionally, the requirement of low privileges for exploitation means that insider threats or compromised low-level accounts could be leveraged to execute attacks. The lack of user interaction needed further increases the risk of automated or remote exploitation. This vulnerability could also be exploited to implant persistent malware or ransomware, amplifying operational and financial damages. The reputational damage from such incidents could be severe, particularly for companies in sectors like finance, healthcare, and government services prevalent in Europe.

Immediate mitigation steps include: 1) Conducting an inventory to identify all instances of Red Art up to version 3.7 within the organization. 2) Applying any available patches or updates from designthemes as soon as they are released. 3) If patches are not yet available, consider disabling or restricting access to vulnerable deserialization functionalities or modules within Red Art. 4) Implement network segmentation and strict access controls to limit the privileges of accounts that can interact with the vulnerable components, minimizing the risk of exploitation. 5) Employ Web Application Firewalls (WAFs) with rules designed to detect and block suspicious serialized object payloads or unusual deserialization patterns. 6) Monitor logs and network traffic for anomalous activity indicative of exploitation attempts, such as unexpected serialized data or object injection signatures. 7) Educate development and security teams about secure deserialization practices to prevent similar vulnerabilities in custom code or future versions. 8) Prepare incident response plans tailored to deserialization attacks to enable rapid containment and remediation if exploitation occurs.
