CVE-2024-21277 Overview
CVE-2024-21277 is a high-severity authorization flaw in the Oracle MES for Process Manufacturing product, part of Oracle E-Business Suite. The vulnerability resides in the Device Integration component and affects supported versions 12.2.3 through 12.2.13. A low-privileged attacker with network access via HTTP can exploit this flaw to compromise the application. Successful exploitation permits unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all data accessible by Oracle MES for Process Manufacturing. Oracle addressed the issue in the October 2024 Critical Patch Update.

Technical Details for CVE-2024-21277
Vulnerability Analysis
The flaw is categorized under CWE-863: Incorrect Authorization. Oracle MES for Process Manufacturing fails to correctly enforce authorization controls in its Device Integration component. An authenticated user with minimal application privileges can issue HTTP requests that operate outside their intended access scope. The vulnerability affects both the confidentiality and integrity of application data, though availability is not impacted according to the published CVSS vector. The EPSS score for this CVE is 0.428% with a percentile of 35.374, indicating a low predicted probability of near-term exploitation.
Root Cause
The root cause is improper authorization enforcement within the Device Integration component of Oracle MES for Process Manufacturing. The application does not adequately validate whether the authenticated principal is entitled to perform the requested action on the target resource. As a result, low-privileged accounts can escalate their effective data access within the module.
Attack Vector
Exploitation occurs over the network using HTTP. The attacker requires valid low-privileged credentials to the Oracle E-Business Suite instance but does not need any user interaction. Because the attack complexity is low and no elevated privileges are required, standard application clients are sufficient to reach the vulnerable endpoints. No public proof-of-concept exploit is available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
No verified public exploitation code is available. Refer to the Oracle Critical Patch Update - October 2024 for authoritative technical detail.
Detection Methods for CVE-2024-21277
Indicators of Compromise
- Unexpected HTTP requests to Oracle MES for Process Manufacturing Device Integration endpoints originating from low-privileged application accounts.
- Unusual create, update, or delete operations on MES process manufacturing records outside a user's normal role scope.
- Anomalous data export or bulk read activity against MES-related database objects.
Detection Strategies
- Enable Oracle E-Business Suite application-level audit logging for the MES for Process Manufacturing module, focusing on Device Integration transactions.
- Correlate web server access logs with application user roles to identify requests that exceed a user's authorized function set.
- Monitor database audit trails (FND_LOG_MESSAGES, AUDIT_TRAIL) for privileged operations initiated by non-administrative accounts.
Monitoring Recommendations
- Alert on HTTP 200 responses to MES Device Integration URLs from user sessions that do not have the corresponding responsibility assigned.
- Baseline normal transaction volumes per MES user role and flag deviations that suggest authorization bypass.
- Review Oracle Access Manager and SSO logs for authenticated sessions performing actions inconsistent with granted responsibilities.
How to Mitigate CVE-2024-21277
Immediate Actions Required
- Apply the October 2024 Oracle Critical Patch Update to all Oracle E-Business Suite instances running MES for Process Manufacturing versions 12.2.3 through 12.2.13.
- Inventory all E-Business Suite deployments and confirm the MES for Process Manufacturing module patch level.
- Review and tighten user responsibilities and function security assignments for accounts with access to the MES module.
Patch Information
Oracle released the fix as part of the Oracle Critical Patch Update - October 2024. Administrators should follow Oracle's documented patch application procedure for E-Business Suite 12.2.x, including running adop in hotpatch or downtime mode as appropriate, and validating the MES for Process Manufacturing module after deployment.
Workarounds
- If immediate patching is not feasible, restrict network access to the Oracle E-Business Suite HTTP endpoints so only trusted internal segments can reach MES Device Integration URLs.
- Temporarily revoke or reduce responsibilities associated with the MES for Process Manufacturing module for non-essential users until the patch is applied.
- Place a reverse proxy or web application firewall in front of the E-Business Suite tier and log all requests targeting the affected component for review.
