CVE-2025-30727: Critical Unauthenticated Remote Takeover in Oracle Scripting

Overview

CVE-2025-30727 is a critical vulnerability affecting the Oracle Scripting component of Oracle E-Business Suite, specifically within the iSurvey Module. Versions from 12.2.3 to 12.2.14 are impacted. The flaw allows an unauthenticated attacker with HTTP network access to completely compromise the system.

What Is the Issue?

This vulnerability is attributed to CWE-306: Missing Authentication for Critical Function. It represents a significant security lapse where critical functionality within Oracle Scripting can be accessed without proper authentication, enabling full system takeover.

According to Oracle’s advisory, exploitation does not require any user interaction or prior privileges. The attacker can leverage this over the network via HTTP, making the vulnerability easily exploitable and particularly dangerous in externally accessible environments.

Technical Details

The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (Critical). The vector is:

• CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
• Attack Vector: Network
• Attack Complexity: Low
• Privileges Required: None
• User Interaction: None
• Scope: Unchanged
• Impact: High for Confidentiality, Integrity, and Availability

SSVC Assessment

The CISA Stakeholder-Specific Vulnerability Categorization (SSVC) analysis further highlights the urgency:

• Exploitation: Not yet observed
• Automatable: No
• Technical Impact: Total

This suggests that while the vulnerability has not yet been exploited, the potential impact is complete system compromise, urging immediate remediation.

Mitigation Recommendations

Oracle has issued patches as part of its April 2025 Critical Patch Update. Organizations using Oracle Scripting 12.2.3 to 12.2.14 should:

• Apply the latest patches immediately
• Restrict network access to the iSurvey module if immediate patching is not possible
• Monitor for unusual access patterns or administrative actions
