CVE-2025-21541
📋 TL;DR
This vulnerability in Oracle Workflow (part of Oracle E-Business Suite) allows authenticated attackers with low privileges to modify or delete some data and read a subset of data they shouldn't have access to. It affects Oracle E-Business Suite versions 12.2.3 through 12.2.14. Attackers can exploit this over HTTP without requiring user interaction.
💻 Affected Systems
- Oracle E-Business Suite
📦 What is this software?
Workflow by Oracle
⚠️ Risk & Real-World Impact
Worst Case
Attackers could manipulate workflow data, potentially disrupting business processes, altering approval chains, or accessing sensitive information stored in workflow components.
Likely Case
Attackers with existing low-privilege access could escalate privileges by modifying workflow configurations or accessing data beyond their authorization level.
If Mitigated
With proper network segmentation and strict access controls, impact would be limited to isolated workflow data manipulation within the attacker's authorized scope.
🎯 Exploit Status
CVSS indicates 'easily exploitable' with low attack complexity. Requires authenticated access but only low privileges.
