CVE-2017-7313 in E-Business
Summary
by MITRE
An issue was discovered in Personify360 e-Business 7.5.2 through 7.6.1. When going to the /TabId/275 URI, it is possible to read any customer name, master Customer Id, and email address. In other words, anyone can search for users/customers in the system - no authentication is required.

The vulnerability identified as CVE-2017-7313 represents a critical authentication bypass flaw within the Personify360 e-Business platform version 7.5.2 through 7.6.1. This security weakness resides in the application's handling of requests to the specific URI path /TabId/275 which serves as an entry point for customer data retrieval. The flaw stems from insufficient access controls and authentication mechanisms that fail to properly validate user credentials before granting access to sensitive customer information. The vulnerability allows any unauthenticated attacker to exploit the system's search functionality and extract customer data including names, master Customer Ids, and email addresses through simple HTTP requests. This represents a fundamental failure in the application's security architecture where sensitive data exposure occurs without any form of user authentication or authorization checks.
The technical implementation of this vulnerability demonstrates a classic case of insufficient authorization controls, which aligns with CWE-285, specifically addressing issues related to improper authorization within applications. The flaw operates at the application layer where the system fails to enforce proper access controls when processing requests to the /TabId/275 endpoint. Attackers can leverage this vulnerability by simply constructing HTTP requests to the affected URI, bypassing any authentication mechanisms that should normally be required to access customer records. The system's lack of input validation and authentication checks creates an attack surface where sensitive personally identifiable information (PII) becomes accessible to anyone who knows the target URI structure. This vulnerability directly violates the principle of least privilege and demonstrates poor security design in the application's access control implementation.
The operational impact of this vulnerability extends far beyond simple information disclosure, as it provides attackers with substantial customer data that can be used for various malicious activities including identity theft, targeted phishing campaigns, and social engineering attacks. The exposed information includes customer names, master Customer Ids, and email addresses which together form a comprehensive profile of system users. This type of data exposure represents a serious breach of customer privacy and could lead to significant regulatory compliance violations under data protection laws such as GDPR, CCPA, and other applicable regulations. The vulnerability affects organizations using Personify360 e-Business versions 7.5.2 through 7.6.1, potentially exposing thousands of customer records to unauthorized access. The impact is particularly severe because the vulnerability requires no special privileges or credentials to exploit, making it highly accessible to attackers.
Organizations affected by CVE-2017-7313 should immediately implement comprehensive mitigations to address this vulnerability. The primary remediation involves implementing proper authentication and authorization controls at the /TabId/275 endpoint and all similar URI paths within the application. Security measures should include mandatory user authentication for all customer data access, implementation of role-based access controls, and proper input validation to prevent unauthorized data retrieval. Additionally, organizations should conduct thorough security assessments to identify other endpoints that may suffer from similar authentication bypass vulnerabilities. The mitigation strategy should also include network-level protections such as firewall rules to restrict access to sensitive endpoints, web application firewalls to detect and block malicious requests, and comprehensive logging to monitor access attempts to the affected URI. From an ATT&CK framework perspective, this vulnerability maps to techniques involving credential access and privilege escalation through insecure application design, emphasizing the need for robust application security controls and regular vulnerability assessments to prevent unauthorized data access.
