CVE-2025-30756 is a vulnerability identified in Oracle REST Data Services (ORDS) version 24.2.0. This vulnerability allows an unauthenticated attacker with network access via HTTP to compromise the ORDS component. The attack requires human interaction from a person other than the attacker, indicating a social engineering element or user-triggered action is necessary for exploitation. The vulnerability is categorized under CWE-352, which relates to Cross-Site Request Forgery (CSRF), suggesting that the attack vector involves tricking an authenticated user into performing unintended actions. Successful exploitation can lead to unauthorized read access to some data accessible through ORDS, as well as unauthorized update, insert, or delete operations on that data. The scope of impact extends beyond ORDS itself, potentially affecting additional Oracle products that rely on or integrate with ORDS, indicating a scope change. The CVSS 3.1 base score is 6.1 (medium severity), with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, meaning the attack can be launched remotely over the network with low attack complexity, no privileges required, but user interaction is necessary. The vulnerability impacts confidentiality and integrity but does not affect availability. No known exploits are currently reported in the wild, and no patches are listed yet, indicating that organizations should prepare to apply updates once available and implement interim mitigations. The vulnerability’s requirement for user interaction and unauthenticated network access makes it a significant risk, especially in environments where ORDS is exposed to external or internal networks and users might be susceptible to social engineering or phishing attacks.

For European organizations, the impact of CVE-2025-30756 can be substantial, particularly for those relying on Oracle REST Data Services to provide RESTful interfaces to Oracle databases and applications. Unauthorized read access could lead to data leakage of sensitive or regulated information, potentially violating GDPR and other data protection regulations. Unauthorized modification (update, insert, delete) of data can compromise data integrity, leading to corrupted business processes, financial inaccuracies, or operational disruptions. The scope change implies that other Oracle products integrated with ORDS could also be compromised, amplifying the risk. Given that many European enterprises, government agencies, and critical infrastructure providers use Oracle products extensively, this vulnerability could affect a wide range of sectors including finance, healthcare, public administration, and manufacturing. The requirement for user interaction means that phishing or social engineering campaigns could be used to trigger the exploit, increasing the risk in environments with less mature security awareness programs. The medium severity score suggests that while the vulnerability is not immediately critical, the potential for data compromise and integrity loss is significant enough to warrant urgent attention.

1. Immediate mitigation should focus on reducing exposure of Oracle REST Data Services interfaces to untrusted networks. Restrict network access to ORDS endpoints using firewalls, VPNs, or network segmentation to limit attacker access. 2. Implement strict Content Security Policy (CSP) and anti-CSRF tokens in web applications interfacing with ORDS to prevent CSRF attacks. 3. Enhance user awareness and training programs to recognize and avoid social engineering or phishing attempts that could trigger the required user interaction. 4. Monitor logs and network traffic for unusual HTTP requests or patterns indicative of exploitation attempts, especially those involving state-changing operations (update, insert, delete). 5. Apply principle of least privilege to database and ORDS configurations, ensuring that accounts exposed via ORDS have minimal permissions necessary to reduce impact if compromised. 6. Stay alert for official Oracle patches or updates addressing CVE-2025-30756 and prioritize their deployment in testing and production environments. 7. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block CSRF and suspicious ORDS traffic. 8. Conduct regular security assessments and penetration tests focusing on ORDS interfaces to identify and remediate weaknesses proactively.
