CVE-2017-10112 in iStore
Summary
by MITRE
Vulnerability in the Oracle iStore component of Oracle E-Business Suite (subcomponent: User Registration). 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 iStore. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle iStore, 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 iStore accessible data as well as unauthorized update, insert or delete access to some of Oracle iStore 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-2017-10112 resides within the Oracle iStore component of the Oracle E-Business Suite, specifically within the User Registration subcomponent. This weakness represents a significant security flaw that affects multiple versions of the Oracle 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 at the application layer and demonstrates characteristics that make it particularly dangerous due to its ease of exploitation and the broad impact it can have on affected systems. The flaw allows attackers to compromise the iStore functionality without requiring authentication, making it an attractive target for malicious actors seeking unauthorized access to sensitive business data.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the user registration process. Attackers can exploit this weakness through HTTP network connections without requiring prior authentication credentials, which aligns with the CVSS vector showing network accessibility with low attack complexity. The vulnerability requires human interaction from users other than the attacker, suggesting that the exploitation may involve social engineering elements or targeted phishing campaigns where legitimate users are tricked into performing actions that facilitate the attack. This characteristic places the vulnerability in the CWE-284 category of improper access control, which is a fundamental security principle that should be maintained throughout application design.
The operational impact of this vulnerability is substantial and multifaceted, as demonstrated by the CVSS 3.0 base score of 8.2 which indicates high severity. Successful exploitation can result in unauthorized access to critical data within Oracle iStore, potentially exposing sensitive business information including customer data, financial records, and proprietary business information. The vulnerability also allows for unauthorized update, insert, or delete operations on Oracle iStore accessible data, which could lead to data corruption, manipulation, or complete data loss. The security impact extends beyond just the iStore component itself, as the attack may significantly affect additional products within the Oracle E-Business Suite ecosystem, creating cascading security implications that could compromise the entire suite's integrity. The confidentiality impact is rated as high, indicating that attackers could gain access to sensitive information that could be used for financial gain, competitive advantage, or further exploitation of the enterprise environment.
Organizations affected by this vulnerability should implement immediate mitigations to protect their systems from exploitation. The recommended approach includes applying the relevant Oracle security patches and updates as provided in the Oracle Critical Patch Updates (CPU) releases. Network segmentation and access controls should be enhanced to limit exposure of the affected iStore components to unauthorized network access. Additionally, monitoring and logging mechanisms should be strengthened to detect potential exploitation attempts through unusual access patterns or unauthorized data modification activities. From an ATT&CK framework perspective, this vulnerability aligns with techniques involving unauthorized access and credential exposure, potentially enabling adversaries to move laterally within the network or establish persistence through compromised user accounts. The vulnerability also represents a significant risk for privilege escalation attacks and data exfiltration activities that could be leveraged by sophisticated threat actors to gain deeper access to enterprise resources.
