CVE-2025-61763 is a vulnerability identified in Oracle Essbase version 21.7.3.0.0, specifically within the Essbase Web Platform component. This vulnerability allows an attacker with low privileges and network access via HTTP to compromise the system without requiring user interaction. The attacker can perform unauthorized creation, deletion, or modification of critical data stored or accessible through Oracle Essbase. The vulnerability stems from improper access control (CWE-284), enabling privilege escalation or unauthorized data manipulation. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) indicates that the attack can be launched remotely over the network with low attack complexity and requires only low privileges but no user interaction. The impact is high on confidentiality and integrity, as attackers can access or alter sensitive financial or business intelligence data, but availability is not affected. No known exploits are currently in the wild, and no official patches have been published at the time of disclosure. Oracle Essbase is widely used for enterprise performance management and financial analytics, making this vulnerability critical for organizations relying on accurate and secure data processing.

For European organizations, the impact of CVE-2025-61763 can be severe, particularly for enterprises in finance, manufacturing, and utilities sectors that rely heavily on Oracle Essbase for business intelligence and financial reporting. Unauthorized data modification or deletion can lead to inaccurate financial statements, regulatory non-compliance, and loss of stakeholder trust. Confidential data exposure could result in intellectual property theft or competitive disadvantage. Given the vulnerability allows remote exploitation with low privileges, attackers could leverage compromised internal accounts or weakly protected network segments to escalate privileges and manipulate critical data. This could disrupt decision-making processes and potentially cause financial losses or legal penalties under GDPR and other data protection regulations. The lack of availability impact reduces the chance of service outages but does not mitigate the risk of data integrity and confidentiality breaches.

European organizations should immediately audit and restrict network access to Oracle Essbase Web Platform interfaces, limiting exposure to trusted internal networks only. Implement strict access controls and enforce the principle of least privilege for all Oracle Essbase users, ensuring that accounts with network access have minimal permissions. Monitor and log all access and modification activities within Essbase to detect anomalous behavior indicative of exploitation attempts. Employ network segmentation and firewall rules to isolate Essbase servers from untrusted networks. Until an official patch is released by Oracle, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious HTTP requests targeting Essbase endpoints. Regularly review Oracle security advisories for updates and apply patches promptly once available. Additionally, conduct penetration testing focused on Essbase to identify potential exploitation paths and remediate them proactively.
