CVE-2025-50107: Oracle Work Queue Auth Bypass Flaw

CVE-2025-50107 Overview

CVE-2025-50107 is a vulnerability in the Oracle Universal Work Queue product of Oracle E-Business Suite, specifically within the Request handling component. Affected versions span 12.2.5 through 12.2.14. An unauthenticated attacker with network access via HTTP can exploit the flaw, though successful exploitation requires user interaction from a victim other than the attacker. The vulnerability carries a scope change, meaning attacks may impact additional products beyond Oracle Universal Work Queue. Successful exploitation can result in unauthorized update, insert, or delete access to some accessible data, as well as unauthorized read access to a subset of accessible data. The weakness is classified under [CWE-284] (Improper Access Control).

Critical Impact
An unauthenticated network attacker who tricks a user into interacting with a crafted HTTP request can achieve unauthorized read and modification of data across product boundaries via scope change.

Affected Products

Oracle Universal Work Queue 12.2.5
Oracle Universal Work Queue 12.2.6 through 12.2.13

Technical Details for CVE-2025-50107

Vulnerability Analysis

The vulnerability resides in the Request handling component of Oracle Universal Work Queue, a module within Oracle E-Business Suite that manages work distribution across contact center and back-office agents. Oracle classifies the issue under Improper Access Control [CWE-284]. The advisory notes that exploitation requires human interaction from a person other than the attacker, which is consistent with cross-user attack patterns where a victim is induced to load an attacker-crafted URL or form submission. Because the vulnerability produces a scope change, code executing within the Universal Work Queue context can affect resources managed by other Oracle E-Business Suite components. Impact is limited to confidentiality and integrity, with no direct availability effect.

Root Cause

Oracle has not released detailed technical internals, but the [CWE-284] classification combined with the requirement for victim interaction indicates that the Request handling logic fails to enforce sufficient authorization or origin checks on incoming HTTP requests. This class of flaw commonly appears when server-side handlers trust request parameters or referrer context without validating that the requesting user is authorized for the target resource.

Attack Vector

An unauthenticated remote attacker delivers a crafted HTTP request or link to a legitimate Oracle E-Business Suite user. When that user processes the request within their authenticated session, the Request handling component performs privileged operations on the attacker's behalf. The scope change in the CVSS vector reflects that these operations can reach data owned by adjacent E-Business Suite products.

No verified public proof-of-concept code is available for this vulnerability. Refer to the Oracle Security Alert July 2025 for authoritative remediation guidance.

Detection Methods for CVE-2025-50107

Indicators of Compromise

Unexpected HTTP POST or GET requests to Oracle Universal Work Queue endpoints originating from external referrers or unknown user-agents.
Session logs showing data modification actions immediately following user navigation from untrusted external links.
Audit trail entries indicating insert, update, or delete operations on Universal Work Queue records without corresponding legitimate business workflow context.

Detection Strategies

Enable and review Oracle E-Business Suite application audit logging for Universal Work Queue transactions, correlating request source and user session origin.
Deploy a web application firewall in front of the E-Business Suite front-end to identify anomalous HTTP request patterns targeting Universal Work Queue URLs.
Baseline normal Universal Work Queue request volumes and alert on deviations that coincide with user-initiated navigation events from external domains.

Monitoring Recommendations

Monitor E-Business Suite middle-tier access logs for suspicious OA_HTML and Universal Work Queue servlet paths accessed with cross-origin referrers.
Track database-level DML activity attributed to Universal Work Queue service accounts and alert on volume or pattern anomalies.
Correlate authentication events with subsequent write operations to detect single-request modification patterns typical of cross-site request forgery style abuse.

How to Mitigate CVE-2025-50107

Immediate Actions Required

Apply the Oracle Critical Patch Update from July 2025 to all Oracle E-Business Suite instances running Universal Work Queue versions 12.2.5 through 12.2.14.
Inventory all internet-facing Oracle E-Business Suite deployments and prioritize patching for those exposed beyond the internal network.
Communicate to end users the risk of clicking untrusted links while authenticated to Oracle E-Business Suite, given the user-interaction requirement.

Patch Information

Oracle addressed CVE-2025-50107 in the July 2025 Critical Patch Update. Administrators should consult the Oracle Security Alert July 2025 for the specific patch identifiers applicable to their Universal Work Queue release and apply them following Oracle's E-Business Suite patching procedure.

Workarounds

Restrict network exposure of the Oracle E-Business Suite front-end so that Universal Work Queue endpoints are reachable only from trusted networks or via VPN.
Enforce strict same-origin and referrer policies at the reverse proxy or WAF layer for Universal Work Queue URLs until patching is complete.
Reduce the number of users with Universal Work Queue responsibilities to the minimum required, limiting the pool of potential victims for interaction-based exploitation.

bash

# Example WAF rule concept: block cross-origin requests to Universal Work Queue endpoints
# Adapt syntax to your WAF platform (ModSecurity shown for illustration)
