The vulnerability identified as CVE-2015-10022 represents a critical sql injection flaw within the IISH nlgis2 application, specifically affecting the scripts/etl/custom_import.pl file. This vulnerability exposes the application to unauthorized database access and potential data compromise through malicious sql queries. The flaw occurs when user-supplied input is not properly sanitized before being incorporated into sql statements, creating an attack vector that allows adversaries to manipulate database operations and potentially extract sensitive information.
The technical implementation of this vulnerability stems from inadequate input validation and parameter sanitization within the custom_import.pl script. When the application processes external data through this module, it directly incorporates user-provided parameters into sql queries without proper escaping or parameterization techniques. This design flaw aligns with CWE-89, which specifically addresses sql injection vulnerabilities where untrusted data is used in sql command construction. The vulnerability's classification as critical indicates the potential for severe impact including complete database compromise, data exfiltration, and unauthorized administrative access to the underlying database system.
Operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and business disruption. Attackers exploiting this flaw could gain read access to sensitive databases containing personal information, financial records, or proprietary business data. The vulnerability's presence in an etl (extract, transform, load) script suggests that it may affect data integration processes, potentially allowing attackers to manipulate or corrupt data flowing through the system. This represents a significant risk to data integrity and system availability, particularly in environments where automated data processing and integration are critical components of business operations.
Security mitigation for this vulnerability requires immediate application of the provided patch identified by the commit hash 8bdb6fcf7209584eaf1232437f0f53e735b2b34c. Organizations should also implement additional defensive measures including input validation at multiple layers, parameterized queries, and database access controls to limit the potential impact of any remaining vulnerabilities. The ATT&CK framework's T1190 technique for exploit public-facing application aligns with this vulnerability's exploitation methods, while T1071.004 for application layer protocol and T1046 for network service scanning may represent additional attack vectors that should be monitored. Organizations should conduct thorough security assessments to identify similar vulnerabilities in other components of their data processing infrastructure and implement comprehensive monitoring solutions to detect potential exploitation attempts.
