CVE-2017-3393 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Advanced Outbound Telephony component of Oracle E-Business Suite (subcomponent: Interaction History). Supported versions that are affected are 12.2.3, 12.2.4, 12.2.5 and 12.2.6. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Advanced Outbound Telephony. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Advanced Outbound Telephony, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Advanced Outbound Telephony accessible data as well as unauthorized update, insert or delete access to some of Oracle Advanced Outbound Telephony accessible data. CVSS 3.0 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).

The vulnerability identified as CVE-2017-3393 resides within Oracle Advanced Outbound Telephony component of the Oracle E-Business Suite, specifically within the Interaction History subcomponent. This represents a critical security weakness that affects Oracle E-Business Suite versions 12.2.3 through 12.2.6, making it a widespread issue across multiple supported releases. The vulnerability operates at the application layer and leverages HTTP network protocols to establish unauthorized access points, creating a significant attack surface for malicious actors.
The technical flaw manifests as an authentication bypass mechanism that allows unauthenticated attackers to exploit the system without requiring valid credentials or prior access privileges. This vulnerability falls under CWE-287, which addresses improper authentication issues, and represents a classic case of weak access control implementation. The exploitability factor is rated as easily "exploitable" indicating that the attack vectors are straightforward and require minimal technical expertise to execute successfully. The vulnerability requires only network access via HTTP protocol, making it particularly dangerous as it can be leveraged from remote locations without physical presence.
The operational impact of this vulnerability extends beyond the immediate scope of Oracle Advanced Outbound Telephony, potentially affecting additional Oracle products within the E-Business Suite ecosystem. The CVSS 3.0 score of 8.2 reflects the severity with which security professionals should treat this issue, particularly given the high confidentiality impact and moderate integrity impact ratings. Successful exploitation enables attackers to gain unauthorized access to critical data within the telephony system and provides the capability to modify, insert, or delete information within the accessible data repositories. The requirement for human interaction from individuals other than the attacker suggests that social engineering or user manipulation may be necessary to complete the attack chain, though the core vulnerability remains accessible to network-based attacks.
Security professionals should recognize this vulnerability as part of the broader ATT&CK framework's privilege escalation and credential access tactics, specifically aligning with techniques that involve exploitation of application-level weaknesses. The attack vector analysis indicates that organizations running affected Oracle E-Business Suite versions face significant risk without proper mitigations in place. The vulnerability's classification under CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N demonstrates that network-based attacks can be executed with low complexity, no prior privileges, and require only user interaction, while the scope expansion to critical systems creates cascading security implications.
Organizations should implement immediate mitigations including network segmentation, firewall rules to restrict HTTP access to the affected components, and application-level access controls to limit exposure. The vulnerability's characteristics make it particularly concerning for enterprises that rely heavily on telephony integration within their business processes, as it could potentially lead to data breaches, service disruption, and unauthorized modification of telephony records that may contain sensitive customer information. Patch management strategies should prioritize this vulnerability due to its high severity score and the fact that it affects multiple supported release versions of Oracle E-Business Suite, requiring coordinated remediation efforts across affected systems.
