CVE-2017-3377 in E-Business Suite
Summary
by MITRE
Vulnerability in the Oracle Advanced Outbound Telephony component of Oracle E-Business Suite (subcomponent: User Interface). Supported versions that are affected are 12.1.1, 12.1.2, 12.1.3, 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 v3.0 Base Score 8.2 (Confidentiality and Integrity impacts).

The vulnerability identified as CVE-2017-3377 resides within the Oracle Advanced Outbound Telephony component of Oracle E-Business Suite, specifically affecting the User Interface subcomponent. This flaw represents a critical security weakness that impacts multiple versions of the E-Business Suite including 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5, and 12.2.6. The vulnerability operates under the Common Weakness Enumeration framework as CWE-284, which classifies it as an "Improper Access Control" weakness, indicating inadequate authorization mechanisms that permit unauthorized access to protected resources. The CVSS v3.0 base score of 8.2 reflects the severity of the flaw, with high impact scores for both confidentiality and integrity, demonstrating the potential for significant data compromise.
The technical exploitation of this vulnerability occurs through unauthenticated network access via HTTP protocols, making it particularly dangerous as it requires no prior authentication credentials from the attacker. This characteristic places the vulnerability in the ATT&CK framework under the T1190 technique for "Exploit Public-Facing Application," indicating that attackers can leverage publicly accessible interfaces to gain unauthorized access. The flaw's design allows for complete compromise of the Oracle Advanced Outbound Telephony component, potentially enabling attackers to access all accessible data within this system. The vulnerability's impact extends beyond the immediate component, as successful exploitation can affect additional products within the Oracle E-Business Suite ecosystem, creating cascading security implications across the enterprise environment.
The operational impact of this vulnerability is substantial, as it enables unauthorized access to critical data while simultaneously providing the capability for unauthorized modification of data through update, insert, or delete operations. This dual nature of the vulnerability creates both data exfiltration risks and data integrity threats that can severely compromise business operations. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing techniques might be employed to facilitate exploitation, potentially involving employees who interact with the telephony interface. The vulnerability's classification under CWE-284 and its mapping to ATT&CK techniques indicates that organizations must implement robust access control measures and network segmentation to prevent unauthorized access to sensitive telephony interfaces.
Organizations affected by this vulnerability should prioritize immediate remediation through official Oracle patches and updates, as the flaw's easily exploitable nature makes it a prime target for malicious actors. Network administrators should implement strict access controls and monitoring for HTTP traffic to the affected components, while security teams should conduct comprehensive vulnerability assessments to identify potential exploitation attempts. The implementation of network segmentation and the principle of least privilege can significantly reduce the attack surface, preventing lateral movement within the network if exploitation occurs. Additionally, regular security awareness training for personnel who interact with telephony interfaces can help mitigate the human interaction requirement, reducing the likelihood of successful social engineering attacks that might exploit this vulnerability.
