Summary

CVE-2026-70862 is a critical, remotely exploitable vulnerability in Oracle Application Testing Suite that allows a completely unauthenticated network attacker to compromise the confidentiality and integrity of the application. The flaw is exploitable over HTTP without any user interaction, and successful exploitation grants unauthorized creation, deletion, or modification of critical data, as well as read access to all data accessible to Oracle Application Testing Suite. Oracle disclosed the issue as part of its August 2026 Critical Security Patch Update, rating it 9.1 (Critical).

Technical details

  • Root cause: Oracle’s advisory characterizes this as an easily exploitable flaw in Oracle Application Testing Suite that permits unauthorized access to data without requiring credentials; Oracle has not published low-level technical details (e.g., specific code path or CWE) beyond the risk-matrix summary.
  • Trigger conditions: The vulnerability can be triggered by an attacker with network access to the affected component via HTTP — no authentication or user interaction is required to exploit it.
  • Attack vector: Network (AV:N), Low attack complexity (AC:L), no privileges required (PR:N), no user interaction required (UI:N).
  • Impact: High confidentiality impact and high integrity impact — attackers can read all data accessible to the application and create, delete, or modify critical data. There is no impact to availability (A:N), and the scope is unchanged (S:U).

Affected software

  • Oracle Application Testing Suite, version 13.3.0.1

Severity

  • CVSS v3.1 Base Score: 9.1 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Mitigation and recommended actions

  • Immediate: Apply the patch for Oracle Application Testing Suite included in Oracle’s August 2026 Critical Security Patch Update. Oracle strongly recommends applying the update as soon as possible, as this vulnerability is remotely exploitable without authentication.
  • If patching cannot be performed immediately: Restrict network access to Oracle Application Testing Suite instances to trusted internal networks only, and avoid exposing the affected component directly to the internet until the patch has been applied. Monitor HTTP traffic to the application for anomalous requests as a compensating control.

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.
