The vulnerability identified as CVE-2013-10016 represents a critical sql injection flaw in fanzila WebFinance version 0.5, specifically within the administrative component of the application. This vulnerability resides in the htdocs/admin/save_taxes.php file where improper input validation occurs during the processing of user-supplied data. The flaw manifests when the application fails to properly sanitize or escape the id parameter before incorporating it into sql query constructions, creating an exploitable condition that allows malicious actors to manipulate database operations through crafted input sequences.
The technical implementation of this vulnerability stems from inadequate parameter handling within the web application's backend processing logic. When the id argument is passed to the save_taxes.php script, the application directly incorporates this value into sql statements without appropriate sanitization measures. This design flaw aligns with CWE-89, which categorizes sql injection as a critical weakness in software applications where user-controllable data is improperly integrated into sql command structures. The vulnerability operates at the application layer and requires minimal privileges to exploit, making it particularly dangerous as it can be leveraged by unauthenticated attackers to gain unauthorized access to database resources.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to execute arbitrary sql commands on the underlying database server. Successful exploitation could result in complete database compromise, including data exfiltration, data modification, or even the execution of malicious code on the database server itself. The vulnerability affects the administrative functionality of the WebFinance application, potentially allowing attackers to manipulate tax-related data, modify user accounts, or escalate privileges within the system. This represents a significant risk to financial data integrity and confidentiality, particularly in applications handling sensitive tax information.
Security mitigation for this vulnerability requires immediate implementation of the provided patch identified by the hash 306f170ca2a8203ae3d8f51fb219ba9e05b945e1. Organizations should also implement proper input validation and parameterized query execution throughout the application codebase to prevent similar issues from occurring in other components. The fix should enforce strict type checking and input sanitization for all parameters that are subsequently used in database operations. Additionally, implementing proper access controls and database permissions can limit the damage that could occur even if the vulnerability is exploited, aligning with defense-in-depth principles recommended in the mitre ATT&CK framework for application layer attacks. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities in other application components, ensuring comprehensive protection against sql injection threats across the entire system landscape.
