The vulnerability identified as CVE-2003-0509 represents a critical sql injection flaw affecting Cyberstrong eShop version 4.2 and earlier implementations. This security weakness resides within the web application's handling of user input parameters, specifically targeting the ProductCode parameter across three distinct asp files including 10expandasp 10browseasp and 20reviewasp. The vulnerability allows remote attackers to execute malicious sql commands against the underlying database system through crafted input manipulation.
The technical nature of this flaw stems from insufficient input validation and sanitization within the application's database query construction process. When the ProductCode parameter is processed in any of the affected asp files, the application fails to properly escape or filter special sql characters and commands. This lack of proper input sanitization creates an opening for malicious actors to inject arbitrary sql code that gets executed within the database context. The vulnerability operates at the application layer and specifically targets the database communication channel between the web application and its backend database system.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with the capability to extract sensitive authentication information stored within the database. Successful exploitation could result in unauthorized access to user credentials, administrative privileges, and potentially full database compromise. Attackers could leverage this vulnerability to escalate their privileges, modify or delete critical data, and gain persistent access to the affected system. The remote nature of the attack means that exploitation can occur from any location without requiring physical access to the target system, making it particularly dangerous for web applications handling sensitive user data.
This vulnerability aligns with CWE-89 sql injection which is categorized under the weakness identification and classification system maintained by thecwesite. The attack pattern corresponds to the ATT&CK framework's technique T1190 exploitation for execution and T1078 valid accounts which represents the use of legitimate credentials obtained through compromise. Organizations affected by this vulnerability should implement immediate mitigations including input parameter validation, proper sql query construction using parameterized queries, and regular security assessments. The remediation approach should focus on eliminating direct sql string concatenation and implementing proper input sanitization mechanisms to prevent malicious sql code injection. Additionally, access controls and database privilege management should be reviewed to minimize potential impact from successful exploitation attempts.
