CVE-2017-10409 in iStore
Summary
by MITRE
Vulnerability in the Oracle iStore component of Oracle E-Business Suite (subcomponent: Merchant UI). Supported versions that are affected are 12.1.1, 12.1.2, 12.1.3, 12.2.3, 12.2.4, 12.2.5, 12.2.6 and 12.2.7. 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-2017-10409 resides within the Oracle iStore component of Oracle E-Business Suite, specifically within the Merchant UI subcomponent. This flaw affects multiple versions including 12.1.1 through 12.2.7, representing a significant attack surface across the Oracle E-Business Suite ecosystem. The vulnerability is classified as easily exploitable, meaning that attackers can leverage it without requiring specialized skills or extensive resources to execute successful attacks. The security implications extend beyond just the targeted iStore component, as successful exploitation can potentially impact additional Oracle products within the broader E-Business Suite environment, creating cascading security risks.
The technical nature of this vulnerability stems from insufficient authentication mechanisms within the Merchant UI interface, allowing unauthenticated attackers to gain access to Oracle iStore functionality through standard HTTP network connections. This represents a critical design flaw in the authentication and authorization controls that should normally prevent unauthorized access to sensitive business applications. The CVSS 3.0 scoring system rates this vulnerability at 8.2, indicating high severity with significant confidentiality and integrity impacts. The attack vector AV:N (network) combined with low attack complexity AC:L demonstrates that the vulnerability can be exploited remotely without requiring physical access or specialized tools. The PR:N (no privileges required) and UI:R (requires human interaction) elements indicate that while no prior authentication is needed, successful exploitation typically requires some form of user interaction, though this interaction does not necessarily need to be performed by the attacker.
The operational impact of this vulnerability is severe and multifaceted, potentially allowing attackers to achieve unauthorized access to critical business data stored within Oracle iStore. The confidentiality impact is rated as high (C:H) since attackers could gain access to sensitive commercial information, customer data, and business-critical records. The integrity impact is rated as low to moderate (I:L) indicating that while the primary threat involves data disclosure, attackers could also potentially modify or delete data within the accessible Oracle iStore environment. The lack of availability impact (A:N) suggests that this vulnerability primarily affects data confidentiality and integrity rather than system availability, though the potential for data manipulation could indirectly affect system operations. This vulnerability aligns with CWE-287 (Improper Authentication) and represents a significant risk to enterprise data security, particularly in environments where Oracle E-Business Suite is deployed for mission-critical business operations.
The attack scenario typically involves an unauthenticated network attacker who can access the Oracle iStore Merchant UI through HTTP connections without requiring valid credentials or elevated privileges. The requirement for human interaction (UI:R) suggests that while the vulnerability itself is easily exploitable, successful compromise often requires some form of user engagement, potentially through social engineering or targeted phishing attacks that prompt users to interact with malicious content. Organizations should consider implementing network segmentation and access controls to limit exposure to this vulnerability, while also ensuring that all Oracle E-Business Suite installations are patched with the appropriate security updates from Oracle. The vulnerability demonstrates the importance of maintaining up-to-date security patches and implementing proper network monitoring to detect and prevent unauthorized access attempts to business-critical applications. This type of vulnerability commonly appears in ATT&CK framework as part of the Initial Access and Credential Access phases, where attackers seek to establish persistent access to enterprise environments through weaknesses in application authentication mechanisms.
