CVE-2008-0738 in Candypress Store
Summary
by MITRE
Multiple SQL injection vulnerabilities in CandyPress (CP) 4.1.1.26, and earlier 4.1.x versions, allow remote attackers to execute arbitrary SQL commands via the (1) idcust parameter to (a) ajax_getTiers.asp and (b) ajax_getCust.asp in ajax/, and the (2) tableName parameter to (c) ajax/ajax_tableFields.asp. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

The vulnerability identified as CVE-2008-0738 represents a critical security flaw in CandyPress 4.1.1.26 and earlier versions of the 4.1.x series, specifically targeting SQL injection attack vectors that enable remote code execution. This vulnerability resides within the web application's handling of user-supplied input parameters, creating opportunities for attackers to manipulate database queries through carefully crafted malicious input. The affected components include multiple ajax endpoints within the application's ajax directory, making this a widespread issue that impacts core customer and data management functionalities. The vulnerability's classification aligns with CWE-89, which specifically addresses SQL injection flaws where untrusted data is incorporated into SQL commands without proper sanitization or parameterization.
The technical exploitation of this vulnerability occurs through two primary attack vectors that demonstrate poor input validation practices within the application's backend processing logic. The first vector involves the idcust parameter in two distinct files: ajax_getTiers.asp and ajax_getCust.asp, both located within the ajax directory structure. The second vector targets the tableName parameter within ajax/ajax_tableFields.asp, which also lacks proper input sanitization. These parameters are directly incorporated into SQL queries without adequate escaping or parameterization, allowing attackers to inject malicious SQL code that executes within the database context. The attack mechanism leverages the fundamental weakness where user input flows directly into database query construction, bypassing any application-level validation or sanitization measures.
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 system. This remote code execution capability enables adversaries to manipulate, delete, or extract sensitive customer data, potentially compromising the entire customer database managed by CandyPress. The attack surface is particularly concerning given that these vulnerabilities affect core customer management functions, meaning that any user with access to the application's ajax endpoints could potentially exploit these flaws. The vulnerability's severity is amplified by the fact that it allows for complete database compromise without requiring authentication, making it a high-risk issue that could lead to significant data breaches and regulatory compliance violations.
Security mitigations for this vulnerability should focus on implementing proper input validation and parameterized queries throughout the affected application components. The recommended approach involves replacing direct parameter concatenation with prepared statements or parameterized queries that separate SQL command structure from data values. Additionally, implementing proper input sanitization routines and employing web application firewalls can provide defense-in-depth measures against exploitation attempts. Organizations should also consider implementing least privilege database access controls, ensuring that the application's database user accounts have minimal required permissions. The remediation process must address all three vulnerable files mentioned in the vulnerability description, with particular attention to the ajax directory structure where multiple attack vectors exist. This vulnerability highlights the critical importance of following secure coding practices and adhering to OWASP Top 10 security guidelines for preventing injection flaws, as outlined in the ATT&CK framework's command and control categories where such vulnerabilities are typically exploited for persistent access.
