CVE-2025-61882: 
Oracle E-Business Suite 脆弱性の分析と軽減

CVE-2025-61882 is a critical vulnerability in Oracle E-Business Suite's Concurrent Processing product (specifically in the BI Publisher Integration component) affecting versions 12.2.3-12.2.14. Discovered in August 2025 and publicly disclosed on October 4, 2025, this vulnerability allows unauthenticated attackers with network access via HTTP to achieve remote code execution and potentially take complete control of Oracle Concurrent Processing. The vulnerability has received a CVSS 3.1 Base Score of 9.8, indicating maximum impact on confidentiality, integrity, and availability (Oracle Alert, NVD).

The vulnerability consists of a complex exploit chain involving multiple components: 1) An initial Server-Side Request Forgery (SSRF) vulnerability that allows sending crafted XML requests to internal services, 2) A Carriage Return/Line Feed (CRLF) injection vulnerability enabling header manipulation, 3) An authentication bypass targeting administrative accounts, and 4) Code execution through malicious XSLT template manipulation in Oracle's XML Publisher Template Manager. The attack chain culminates in establishing outbound connections and deploying web shells for persistence (Watchtowr Labs).

Successful exploitation of CVE-2025-61882 can result in complete takeover of Oracle Concurrent Processing, allowing attackers to achieve remote code execution without authentication. The vulnerability has been actively exploited for data exfiltration purposes, with multiple organizations receiving extortion emails related to stolen data (CrowdStrike Blog).

Oracle strongly recommends immediate application of the security updates provided in their advisory. The October 2023 Critical Patch Update is a prerequisite for applying these updates. Additional recommended mitigations include investigating outbound connections from Oracle EBS instances, searching for malicious templates in xdotemplatesvl, investigating suspicious UserID 0 and UserID 6 sessions, temporarily disabling internet access for exposed Oracle EBS services, and securing EBS instances with a web application firewall (Oracle Alert, Arctic Wolf).

The vulnerability has generated significant industry attention, with multiple security firms providing detailed analysis and hunting recommendations. CrowdStrike has released detection rules for their Falcon platform, and security researchers have criticized the spread of speculation about the root cause before official confirmation. The security community has noted that the sophistication of the exploit chain suggests deep knowledge of Oracle EBS, raising concerns about the possibility of additional vulnerabilities (Watchtowr Labs).
