Summary

CVE-2026-46949 is a critical unauthorized access vulnerability in the Internal Operations component of Oracle Advanced Outbound Telephony, a web-based module of Oracle E-Business Suite. The flaw is remotely exploitable over HTTP without any authentication or user interaction, and enables unauthenticated attackers to both read and tamper with sensitive application data. It carries a CVSS v3.1 base score of 9.1 (Critical).

Technical details

  • Root cause: Improper authorization controls in the Internal Operations component, permitting unauthenticated network access to protected functionality via HTTP.
  • Trigger conditions: No authentication, no user interaction, and no special privileges are required — the vulnerability is exploitable by any network-accessible attacker reaching the affected endpoint.
  • Attack vector: Network (HTTP), with low attack complexity; the vulnerability is easily exploitable against internet-exposed Oracle E-Business Suite instances.
  • Impact: Successful exploitation allows unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all Oracle Advanced Outbound Telephony accessible data — resulting in high confidentiality and high integrity impact.

Affected software

  • Oracle Advanced Outbound Telephony (Oracle E-Business Suite) versions 12.2.3 through 12.2.15

Severity

  • CVSS v3.1 Base Score: 9.1 (Critical)
  • Vector String: 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 Oracle’s June 2026 Critical Security Patch Update (CPU) without delay. Patch availability details and installation instructions are provided in My Oracle Support Note CPU172 ("Critical Security Patch Update June 2026 Patch Availability Document for Oracle Products").
  • If patching cannot be applied immediately: Restrict network access to Oracle E-Business Suite HTTP endpoints at the perimeter — block unauthenticated external access to OA Framework/Advanced Outbound Telephony URLs via firewall or web application firewall rules until the patch can be applied. Oracle strongly recommends that customers remain on actively-supported versions.

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.
