Oracle E-Business Suite (EBS) was found to contain a critical zero-day vulnerability, tracked as CVE-2025-61884 and CVE-2025-61882, which allowed unauthenticated remote code execution and was actively exploited by threat actors, including the Clop ransomware group. The vulnerability, present in EBS versions 12.2.3 through 12.2.14, enabled attackers to access sensitive resources without authentication by exploiting a pre-authentication Server-Side Request Forgery (SSRF) flaw. Oracle released an out-of-band security update to address the issue, but did so without publicly acknowledging that the flaw was being actively exploited or that a proof-of-concept exploit had been leaked by the ShinyHunters extortion group. Security researchers and customers confirmed that the patch addressed the SSRF vulnerability used in the attacks. The exploit chain was complex, involving an unauthenticated HTTP POST to a specific servlet, manipulation of return_url parameters to trigger SSRF, CRLF/header injection, HTTP connection reuse, and ultimately the delivery of a malicious XSL stylesheet. This XSLT payload, containing embedded Java code, was processed by the server, leading to arbitrary code execution and the potential for attackers to spawn reverse shells. The Clop ransomware group sent extortion emails to Oracle EBS customers, claiming to have stolen sensitive data by exploiting this flaw, and confirmed their involvement in the campaign. The attack campaign was detected by Mandiant and Google, who observed that multiple threat actors were leveraging the vulnerability for data theft and extortion. The exploit chain demonstrated the risk of chaining multiple weaknesses in enterprise software to achieve full remote code execution. Security vendors, such as Imperva, responded by confirming protection for their customers against this exploit. The incident highlighted Oracle's lack of transparency regarding active exploitation and the public availability of exploit code. The technical details of the exploit, including SSRF, CRLF injection, and XSLT-based code execution, underscored the sophistication of the attack. The vulnerability's exploitation in the wild emphasized the importance of rapid patching and monitoring for signs of compromise in Oracle EBS environments. The campaign also illustrated the ongoing threat posed by ransomware and extortion groups targeting critical business applications. Organizations using Oracle EBS were urged to apply the security update immediately and review their systems for indicators of compromise. The incident raised concerns about the security of widely used enterprise resource planning (ERP) platforms and the need for proactive vulnerability management.

Cl0p ransomware operators launched a widespread extortion campaign targeting Oracle E-Business Suite (EBS) customers by exploiting a previously unknown zero-day vulnerability, later assigned CVE-2024-61882. The campaign began as early as July or August, with Google's threat intelligence team tracking the exploitation weeks before Oracle became aware of the issue. Attackers leveraged the vulnerability to gain unauthorized access to EBS environments, deploying sophisticated multi-stage Java-based implants such as GOLDVEIN, SAGEGIFT, and SAGEWAVE. These implants operated entirely in memory, making detection difficult, and communicated with command-and-control servers using traffic disguised as legitimate TLS handshakes. The payloads were stored directly in the EBS database, and attackers used compromised third-party email services to facilitate their operations. Once data was exfiltrated, Cl0p initiated mass extortion by sending emails to executives, threatening to release stolen information unless a ransom was paid. The attack pattern mirrored previous Cl0p campaigns, notably the MOVEit mass exploitation, indicating a strategic focus on widely used enterprise applications. Oracle responded by releasing emergency patches on October 4th, but by that time, many organizations had already suffered breaches and data theft.
