CVE-2026-61256 in Advanced Inbound Telephony
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Advanced Inbound Telephony product of Oracle E-Business Suite (component: Servers). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Advanced Inbound Telephony. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Advanced Inbound Telephony accessible data as well as unauthorized read access to a subset of Oracle Advanced Inbound Telephony accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Advanced Inbound Telephony. CVSS 3.1 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

The vulnerability resides within Oracle Advanced Inbound Telephony, a component of the Oracle E-Business Suite that handles telephony operations and communications. This system serves as a critical interface for managing inbound call processing and customer interactions within enterprise environments. The affected versions spanning from 12.2.3 through 12.2.15 represent a significant attack surface given their widespread deployment across organizations relying on Oracle's enterprise solutions for business operations and customer service management.
The technical flaw manifests as an insufficient access control mechanism that fails to properly validate user privileges before granting data manipulation capabilities. This vulnerability operates at the application layer where HTTP network requests are processed, allowing attackers with minimal privileges to exploit weaknesses in authentication and authorization controls. The vulnerability's classification as easily exploitable indicates that the attack vector requires no specialized skills or conditions, making it particularly dangerous for organizations with less stringent security controls. The flaw enables unauthorized modification of data through update, insert, and delete operations while simultaneously providing read access to sensitive information.
From an operational impact perspective, this vulnerability creates multiple attack vectors that can significantly compromise enterprise security posture. The ability to perform unauthorized data modifications directly impacts data integrity, potentially corrupting critical customer information, call logs, or telephony configurations that organizations depend upon for business continuity. The read access capabilities expose sensitive data to unauthorized parties, creating confidentiality risks that could include personal identifiable information, customer communication records, or operational details that adversaries might leverage for further attacks. Additionally, the partial denial of service capability can disrupt call processing operations, affecting customer service availability and potentially causing business disruption during critical periods.
The CVSS 3.1 score of 6.3 reflects the balanced impact across confidentiality, integrity, and availability domains, with all three affected at medium severity levels. The attack vector requiring network access via HTTP places this vulnerability within the reach of remote attackers who can exploit it from external networks. The low privilege requirement suggests that even users with minimal system access could potentially leverage this flaw, while the lack of user interaction requirements means the attack can be automated and executed without victim cooperation. This vulnerability maps directly to CWE-285 (Improper Authorization) and aligns with ATT&CK techniques involving privilege escalation and data manipulation operations.
Organizations should implement immediate mitigations including network segmentation to restrict access to Oracle Advanced Inbound Telephony components, applying the latest security patches from Oracle, and implementing robust monitoring for unauthorized access attempts. Security configurations should be reviewed to ensure proper access controls and authentication mechanisms are enforced. Regular vulnerability assessments should be conducted to identify similar weaknesses in other Oracle E-Business Suite components, while incident response procedures should include specific protocols for handling telephony system compromises. The remediation approach must also consider the broader Oracle EBS environment to prevent lateral movement of attacks through interconnected systems.
