Summary

CVE-2026-35292 is a maximum-severity unauthenticated remote code execution vulnerability in the Console component of Oracle WebLogic Server, affecting versions 14.1.2.0.0 and 15.1.1.0.0. With a CVSS 3.1 base score of 10.0, the flaw is network-accessible, requires no privileges and no user interaction, and Oracle’s own advisory states the vulnerability "can result in takeover of WebLogic Server." Organizations running internet-facing WebLogic instances should treat this as an emergency and apply Oracle’s June 2026 Critical Security Patch Update immediately.

Technical details

  • Vulnerable component: WebLogic Server Console component, reachable via HTTP
  • Root cause: An easily exploitable flaw in the Console component allows unauthenticated network requests to compromise the server; Oracle’s advisory does not disclose additional technical specifics at this time
  • Trigger conditions: An unauthenticated attacker with network access to the WebLogic Console over HTTP can exploit this vulnerability without any user interaction or elevated privileges
  • Attack vector: Remote, network-based (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N)
  • Impact: Full compromise of confidentiality, integrity, and availability (C:H/I:H/A:H); the Changed scope (S:C) indicates the impact extends beyond the WebLogic Server process itself to dependent systems and infrastructure

Affected software

  • Oracle WebLogic Server 14.1.2.0.0
  • Oracle WebLogic Server 15.1.1.0.0

Severity

| Metric | Value |
|—|—|
| CVSS v3.1 Base Score | 10.0 (Critical) |
| Vector String | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H |
| Attack Vector | Network |
| Attack Complexity | Low |
| Privileges Required | None |
| User Interaction | None |
| Scope | Changed |
| Confidentiality / Integrity / Availability | High / High / High |

Mitigation and recommended actions

  • Immediate action: Apply Oracle’s June 2026 Critical Security Patch Update (CSPU), which contains the official fix for this vulnerability. Oracle’s advisory is available at https://www.oracle.com/security-alerts/cspujun2026.html
  • If patching cannot be applied immediately:
    • Restrict network access to the WebLogic Server Console (default ports 7001/7002) at the perimeter firewall — the Console should never be directly accessible from the internet
    • Enforce allowlist-based IP restrictions on management interfaces
    • Monitor Console access logs for anomalous or unexpected HTTP requests

Oracle has historically noted that "attackers have been successful because targeted customers had failed to apply available Oracle patches." Given the maximum CVSS score and zero-authentication requirement, delay in patching significantly elevates risk.

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.
