CVE-2026-70814: Oracle Call Center Tech Auth Bypass Flaw

CVE-2026-70814 Overview

CVE-2026-70814 affects the Oracle Call Center Technology product within Oracle E-Business Suite, specifically the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are impacted. An unauthenticated remote attacker with network access via HTTP can exploit this weakness to compromise the affected product. Successful exploitation results in complete takeover of Oracle Call Center Technology, with impacts to confidentiality, integrity, and availability.

While the flaw is classified as difficult to exploit, its network-reachable nature and lack of authentication requirements make it a priority for Oracle E-Business Suite operators. Oracle addressed the issue in its August 2026 security alert cycle.

Critical Impact
Successful exploitation allows an unauthenticated remote attacker to achieve full takeover of Oracle Call Center Technology, compromising confidentiality, integrity, and availability.

Affected Products

Oracle E-Business Suite — Oracle Call Center Technology 12.2.3
Oracle E-Business Suite — Oracle Call Center Technology versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-70814

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Call Center Technology, part of Oracle E-Business Suite. An attacker interacts with the product over HTTP without prior authentication or user interaction. Oracle marks the attack complexity as high, indicating that exploitation depends on specific conditions outside the attacker's direct control, such as timing, configuration, or environmental state.

When those conditions are met, an attacker can subvert the application's expected flow and gain full control over the Call Center Technology instance. Because Oracle Call Center Technology handles customer interaction workflows and integrates with other E-Business Suite modules, a compromise can propagate into adjacent business processes and data stores. Oracle categorizes the outcome as a product takeover with impact across all three CIA properties.

Root Cause

Oracle has not published a technical root cause for CVE-2026-70814. The Oracle Critical Patch Update advisory lists it as an HTTP-reachable flaw in the Internal Operations component that permits unauthenticated compromise. See the Oracle Security Alert for the vendor's authoritative notice.

Attack Vector

Exploitation occurs remotely over HTTP against exposed Oracle Call Center Technology endpoints. No credentials and no user interaction are required. The attacker must satisfy the high-complexity preconditions described by Oracle before achieving takeover. Deployments that expose the E-Business Suite web tier to untrusted networks face the greatest risk.

No public proof-of-concept exploit code was available at the time of NVD publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-70814

Indicators of Compromise

Unexpected HTTP requests to Oracle Call Center Technology Internal Operations endpoints originating from untrusted or unusual source addresses.
New or modified administrative accounts, scheduled concurrent programs, or database objects within the E-Business Suite instance following anomalous HTTP activity.
Outbound network connections initiated by the E-Business Suite application tier to unknown external hosts.

Detection Strategies

Enable and centralize Oracle HTTP Server and E-Business Suite application-tier access logs, and alert on abnormal request volumes or unusual URI patterns targeting Call Center Technology paths.
Baseline normal Internal Operations traffic patterns and flag deviations in request methods, parameters, or user-agent strings.
Correlate web-tier anomalies with database audit trails for privileged operations executed shortly after suspicious HTTP activity.

Monitoring Recommendations

Continuously monitor E-Business Suite hosts for unexpected process execution, file writes to application directories, and unauthorized configuration changes.
Track authentication and privilege changes across Oracle E-Business Suite user accounts and database roles.
Alert on any modifications to Oracle Call Center Technology components or unexpected outbound connections from the middle tier.

How to Mitigate CVE-2026-70814

Immediate Actions Required

Apply the fixes referenced in the Oracle August 2026 Critical Patch Update to all Oracle E-Business Suite environments running Call Center Technology versions 12.2.3 through 12.2.15.
Inventory internet-exposed E-Business Suite instances and restrict inbound HTTP access to trusted networks until patches are deployed.
Review recent web-tier and database audit logs for signs of exploitation attempts targeting Internal Operations endpoints.

Patch Information

Oracle addressed CVE-2026-70814 in the August 2026 Critical Patch Update. Refer to the Oracle Security Alert for the specific patch identifiers and installation guidance corresponding to each supported Oracle E-Business Suite 12.2.x release.

Workarounds

Place Oracle Call Center Technology behind a reverse proxy or web application firewall that enforces strict allow-listing for Internal Operations URIs.
Restrict network reachability of the E-Business Suite web tier to VPN or internal segments only.
Disable or remove unused Oracle Call Center Technology functionality where operationally feasible to reduce exposed attack surface.

bash

# Configuration example: restrict inbound HTTP access to trusted subnets
# Example iptables rule limiting access to the E-Business Suite web tier
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
