The SQL injection vulnerability identified as CVE-2017-2195 affects the Multi Feed Reader application version 2.2.3 and earlier, representing a critical security flaw that undermines the integrity of database operations within the software ecosystem. This vulnerability resides in the application's handling of user input within database queries, creating an attack surface where authenticated users can manipulate the underlying database through carefully crafted inputs. The flaw stems from insufficient input validation and sanitization mechanisms that fail to properly escape or parameterize user-supplied data before incorporating it into SQL command structures. The vulnerability is classified under CWE-89 which specifically addresses SQL injection flaws, where improper neutralization of special elements in SQL commands creates opportunities for attackers to execute unauthorized database operations.
The operational impact of this vulnerability extends beyond simple data theft, as authenticated attackers can leverage the SQL injection to perform arbitrary database commands including data manipulation, extraction, and potentially complete system compromise. Attackers can exploit this weakness to escalate privileges, access sensitive information, modify or delete database records, and potentially gain persistence within the affected environment. The authenticated nature of the attack means that an attacker must first establish credentials within the system, but once authenticated, they can utilize this vulnerability to bypass normal access controls and execute commands that would otherwise be restricted. This represents a significant risk to organizations relying on the Multi Feed Reader for content aggregation and management, as the vulnerability could enable comprehensive database compromise.
The attack vectors remain unspecified in the vulnerability description, suggesting that multiple input points within the application may be susceptible to SQL injection attacks. This broad attack surface increases the likelihood of successful exploitation and makes defensive measures more challenging to implement. The vulnerability demonstrates poor secure coding practices and highlights the importance of implementing proper input validation, parameterized queries, and comprehensive testing procedures. Organizations should consider implementing the principle of least privilege for database connections and employing web application firewalls to detect and prevent SQL injection attempts. Additionally, regular security assessments and code reviews should be conducted to identify similar vulnerabilities within the application's codebase. The remediation approach requires immediate patching to version 2.2.4 or later, which would address the input validation deficiencies and implement proper SQL query parameterization. This vulnerability aligns with ATT&CK technique T1071.005 for application layer protocol use and T1046 for network service scanning, as attackers may first enumerate the application's functionality before exploiting the SQL injection to gain deeper access to the underlying database infrastructure.
