Be the first to know when new zero-days emerge:

Summary

CVE-2026-60670 is a high-severity vulnerability in the Client System Analyzer component of Oracle Applications Technology Stack, part of Oracle E-Business Suite. An unauthenticated remote attacker with network access via HTTP can exploit this flaw to achieve complete takeover of the affected system. The vulnerability was disclosed on July 21, 2026 as part of Oracle’s July 2026 Critical Patch Update and carries a CVSS v3.1 base score of 8.1 (HIGH).

Technical details

  • Affected component: Client System Analyzer within Oracle Applications Technology Stack (Oracle E-Business Suite)
  • Attack vector: Network-accessible via HTTP — no authentication or user interaction required
  • Attack complexity: High (AC:H); while exploitation is not trivial, this is not a disqualifying factor given the complete impact potential
  • Privileges required: None — the vulnerability is exploitable by an unauthenticated attacker
  • Impact: Complete compromise of confidentiality, integrity, and availability — Oracle classifies the outcome as full takeover of the Oracle Applications Technology Stack

Affected software

  • Oracle Applications Technology Stack (Oracle E-Business Suite) versions 12.2.3 through 12.2.15

Severity

  • CVSS v3.1 Base Score: 8.1 (HIGH)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate action: Apply the patches provided in Oracle’s July 2026 Critical Patch Update (CPU), which addresses CVE-2026-60670 across all affected Oracle E-Business Suite 12.2.x versions. Refer to the official Oracle CPU advisory for the applicable patch bundle.
  • Network mitigation (if patching is not immediately feasible): Restrict external network access to Oracle E-Business Suite endpoints, particularly those associated with the Client System Analyzer component; enforce perimeter controls to limit exposure to trusted networks only.
  • Monitoring: Review access logs for anomalous unauthenticated HTTP requests targeting Oracle Applications Technology Stack URLs and server components.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
