CVE-2025-30745 is a medium-severity vulnerability affecting Oracle MES for Process Manufacturing, a component of the Oracle E-Business Suite focused on device integration. The affected versions are 12.2.12 through 12.2.13. This vulnerability allows an unauthenticated attacker with network access via HTTP to exploit the system. Although no privileges are required, successful exploitation depends on human interaction from a user other than the attacker, indicating a social engineering vector or user-assisted attack scenario. The vulnerability has a scope change, meaning that while it resides in Oracle MES for Process Manufacturing, it may impact additional Oracle products or components beyond the initially affected module. Successful exploitation can lead to unauthorized read access to some data and unauthorized update, insert, or delete operations on accessible data within Oracle MES for Process Manufacturing. The CVSS 3.1 base score is 6.1, reflecting a medium severity with low complexity (AC:L), no privileges required (PR:N), network attack vector (AV:N), and user interaction required (UI:R). The impact affects confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches or mitigations are linked in the provided data. The vulnerability's requirement for user interaction suggests phishing or social engineering could be used to trigger the exploit, potentially leveraging HTTP-based requests to manipulate the system. The scope change indicates that the attack could propagate or affect other Oracle E-Business Suite components, increasing the potential impact beyond the MES module alone.

For European organizations, particularly those in manufacturing and process industries relying on Oracle MES for Process Manufacturing, this vulnerability poses a significant risk to data integrity and confidentiality. Unauthorized modification of manufacturing data could disrupt production processes, lead to incorrect product formulations, or cause compliance violations with industry regulations such as REACH or GMP. Unauthorized read access could expose sensitive intellectual property or operational data, potentially leading to industrial espionage or competitive disadvantage. The requirement for user interaction means that employees could be targeted via phishing campaigns, increasing the risk of successful exploitation. Given Oracle's widespread use in European manufacturing sectors, the vulnerability could affect critical infrastructure and supply chains, potentially causing operational delays and financial losses. The scope change further raises concerns about cascading effects on other Oracle E-Business Suite components, amplifying the potential damage. While availability is not directly impacted, the integrity and confidentiality breaches alone could have severe operational and reputational consequences for affected organizations.

European organizations should implement targeted mitigations beyond generic patching advice. First, they should immediately audit their Oracle MES for Process Manufacturing installations to identify affected versions (12.2.12 to 12.2.13) and prioritize upgrading to unaffected versions once patches become available. Until patches are released, organizations should restrict network access to Oracle MES HTTP interfaces by implementing strict firewall rules and network segmentation, limiting exposure to trusted internal networks only. Deploying web application firewalls (WAFs) with custom rules to detect and block suspicious HTTP requests targeting Oracle MES endpoints can provide an additional layer of defense. Since user interaction is required, organizations must enhance security awareness training focused on phishing and social engineering risks, specifically tailored to manufacturing and Oracle system users. Monitoring user activity and anomalous data modification patterns within Oracle MES should be increased to detect potential exploitation attempts early. Implementing multi-factor authentication (MFA) for access to Oracle E-Business Suite components, where feasible, can reduce the risk of unauthorized access. Finally, organizations should prepare incident response plans that include Oracle MES compromise scenarios to minimize impact if exploitation occurs.
