AI Analysis
Technical Summary
This vulnerability affects Oracle Security Service within Oracle Fusion Middleware, specifically versions 12.2.1.4.0 and 12.1.3.0.0. It involves the Oracle SSL API component and allows a low privileged attacker with network access over HTTPS to compromise the service. Exploitation requires user interaction from a third party. The impact includes unauthorized creation, deletion, or modification of critical data or full access to all data accessible by the Oracle Security Service. The CVSS 3.1 vector indicates network attack vector, high attack complexity, low privileges required, user interaction required, unchanged scope, and high confidentiality and integrity impacts with no availability impact. The vulnerability is categorized under CWE-284 (Improper Access Control). Oracle’s April 2026 Critical Patch Update advisory references this vulnerability among others but does not explicitly confirm a dedicated patch or remediation level for it. Customers should review the advisory and apply relevant patches promptly.
Potential Impact
Successful exploitation can result in unauthorized creation, deletion, or modification of critical data or complete access to all data accessible by Oracle Security Service. This compromises confidentiality and integrity of the affected system. The vulnerability requires network access via HTTPS and user interaction, limiting ease of exploitation. There are no known exploits in the wild at the time of publication. The CVSS score of 6.4 reflects a medium severity impact primarily on confidentiality and integrity.
Mitigation Recommendations
Oracle’s April 2026 Critical Patch Update advisory includes multiple security patches for Fusion Middleware products, including Oracle Security Service. Customers are strongly advised to apply the April 2026 Critical Patch Update without delay to address this vulnerability and others. The vendor advisory does not explicitly confirm a dedicated patch for CVE-2026-35252, so customers should monitor Oracle’s security alerts and apply all relevant patches as they become available. Maintaining actively supported versions and timely patching is critical. No alternative mitigations or workarounds are specified in the advisory.
