CVE-2026-70790 in Telecommunications Billing Integrator
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Telecommunications Billing Integrator product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Telecommunications Billing Integrator. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Telecommunications Billing Integrator, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Telecommunications Billing Integrator accessible data. CVSS 3.1 Base Score 7.4 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle Telecommunications Billing Integrator, a critical module within the broader Oracle E-Business Suite ecosystem designed to manage billing processes for telecommunications providers. This security flaw affects supported software versions ranging from 12.2.3 through 12.2.15. The core technical deficiency allows an unauthenticated attacker who possesses network access via HTTP to compromise the integrity of the application. Unlike many high-severity vulnerabilities that can be exploited entirely remotely and automatically, this specific issue requires human interaction. Specifically, a victim other than the attacker must perform certain actions or interact with maliciously crafted content, which serves as a necessary step in the exploitation chain. This social engineering aspect introduces a layer of complexity for potential adversaries but does not eliminate the severity given the high impact on data integrity.
From an operational perspective, the successful exploitation of this vulnerability leads to significant unauthorized modifications within the Oracle Telecommunications Billing Integrator environment. The attacker gains the ability to create, delete, or modify critical data and all accessible information managed by the application. In a telecommunications billing context, such capabilities are particularly dangerous as they can lead to financial fraud, incorrect customer billing records, manipulation of service entitlements, or destruction of essential operational logs. Because the vulnerability is located in Oracle Telecommunications Billing Integrator but attacks may significantly impact additional products due to shared underlying architecture or data dependencies, there is a scope change that amplifies the risk beyond just this single module. This interconnectedness means that compromising one component can cascade into broader system instability or security breaches across other integrated services within the E-Business Suite deployment.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 7.4, which classifies it as High Severity. The primary impact vector is Integrity, with no direct impact on Confidentiality or Availability in the base score calculation. The attack vector is Network (AV:N), indicating remote exploitability over standard network protocols like HTTP without requiring physical access to the target system. The Attack Complexity is Low (AC:L), meaning that specialized conditions are not required for exploitation beyond the initial setup, and Privileges Required are None (PR:N), allowing unauthenticated users to initiate the attack sequence. However, User Interaction is marked as Required (UI:R), necessitating a victim's participation in the exploit process. The Scope is Changed (S:C), confirming that an attacker can affect resources outside of the vulnerable component, thereby increasing the overall risk profile for organizations relying on this suite for critical billing operations.
In terms of industry standard classifications, this vulnerability aligns with CWE-79, which covers Cross-Site Scripting vulnerabilities where untrusted data is not properly validated before being used in web pages, potentially leading to code execution or data manipulation via browser interactions. It also relates closely to CWE-602, Client-side Injection Leading to CSRF, if the exploitation relies on tricking a user into performing state-changing requests. From an offensive security framework perspective, this behavior maps to MITRE ATT&CK techniques involving Social Engineering and potentially Drive-by Code Execution or Phishing for Information depending on how human interaction is solicited. The requirement for user interaction suggests that threat actors would likely employ phishing campaigns or malicious web content delivery mechanisms to trigger the vulnerability in a live environment.
Mitigation strategies must address both technical controls and organizational processes. Oracle has released patches for this issue, and immediate application of these updates to all affected versions between 12.2.3 and 12.2.15 is the primary remediation step. Organizations should prioritize patching systems that are exposed to untrusted networks or the public internet. In addition to patching, implementing strict input validation on server-side components can help mitigate similar flaws in other applications within the suite. Network segmentation strategies should be employed to limit HTTP access to only authorized administrative interfaces and trusted internal subnets where possible. Furthermore, security awareness training for employees is crucial given the user interaction requirement; users must be educated to recognize suspicious links or content that might trigger such vulnerabilities. Regular vulnerability scanning and penetration testing focused on web application integrity checks will help identify similar weaknesses before they can be exploited by malicious actors seeking financial gain through billing system manipulation.
