CVE-2017-15329 in UMA
Summary
by MITRE
Huawei UMA V200R001C00 has a SQL injection vulnerability in the operation and maintenance module. An attacker logs in to the system as a common user and sends crafted HTTP requests that contain malicious SQL statements to the affected system. Due to a lack of input validation on HTTP requests that contain user-supplied input, successful exploitation may allow the attacker to execute arbitrary SQL queries.

The vulnerability CVE-2017-15329 represents a critical SQL injection flaw within Huawei UMA V200R001C00's operation and maintenance module, demonstrating a fundamental weakness in input validation mechanisms that directly compromises system integrity. This vulnerability specifically affects the administrative interface of the Huawei User Management Application, which serves as a critical component for managing user access and system operations within the telecommunications infrastructure. The flaw arises from insufficient sanitization of user-supplied input within HTTP request parameters, creating an exploitable entry point that bypasses normal authentication and authorization controls.
The technical exploitation of this vulnerability follows a well-established attack pattern where an authenticated regular user can leverage crafted HTTP requests containing malicious SQL payloads to manipulate the underlying database operations. This represents a classic SQL injection attack vector that falls under CWE-89, which specifically addresses improper neutralization of special elements used in SQL commands. The vulnerability's impact is particularly severe because it operates within the operation and maintenance module, which typically possesses elevated privileges and access to sensitive system data, user credentials, and configuration information. Attackers can construct malicious SQL statements that bypass normal input validation checks, allowing them to execute arbitrary database queries and potentially gain unauthorized access to the system's backend database.
From an operational perspective, this vulnerability creates significant risk for organizations relying on Huawei UMA systems, as it enables attackers to escalate privileges from standard user accounts to administrative levels without requiring additional authentication credentials. The attack surface is particularly concerning because it does not require privileged access initially, making it accessible to any user who can authenticate to the system. Successful exploitation could result in complete database compromise, data exfiltration, modification of user accounts, and potential system takeover. The vulnerability also aligns with ATT&CK technique T1078 which covers legitimate credentials use for persistence and privilege escalation, as attackers can leverage the compromised system to maintain access and expand their operational capabilities.
Organizations should implement immediate mitigations including comprehensive input validation and sanitization of all user-supplied data within HTTP request parameters, deployment of web application firewalls to detect and block malicious SQL injection patterns, and implementation of least privilege access controls for the operation and maintenance module. The vulnerability demonstrates the critical importance of proper input validation and output encoding as outlined in OWASP Top 10 A03:2021, which specifically addresses injection flaws that remain among the most prevalent and dangerous web application security vulnerabilities. System administrators should also conduct regular security assessments of administrative interfaces and ensure that all network components are updated with the latest security patches provided by Huawei to prevent exploitation of known vulnerabilities.
