The vulnerability identified as CVE-2006-5935 represents a critical sql injection flaw within the ShopSystems e-commerce platform version 4.0 and earlier. This vulnerability specifically affects the index.php script and exploits the sessid parameter to allow remote attackers to execute arbitrary sql commands on the underlying database server. The flaw stems from inadequate input validation and sanitization of user-supplied data, creating an exploitable entry point for malicious actors to bypass authentication mechanisms and gain unauthorized access to sensitive database resources.
This sql injection vulnerability falls under the common weakness enumeration category CWE-89, which specifically addresses sql injection attacks where untrusted data is directly incorporated into sql queries without proper sanitization. The attack vector operates through the sessid parameter that is typically used to maintain user session state within web applications. When this parameter is not properly validated or escaped before being incorporated into sql queries, attackers can inject malicious sql payloads that manipulate the database operations. The vulnerability enables attackers to perform unauthorized data access, modification, or deletion operations, potentially leading to complete database compromise and unauthorized administrative access to the shop systems.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to escalate privileges and manipulate the entire e-commerce platform. Remote attackers can leverage this vulnerability to extract customer information, including personal details and payment data, modify product catalogs, alter pricing structures, and potentially gain administrative control over the entire shop system. The implications are particularly severe for e-commerce platforms where sensitive customer data and financial transactions are processed, as the vulnerability could lead to significant financial losses, regulatory compliance violations, and reputational damage.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and parameterized queries to prevent sql injection attacks. Organizations should immediately upgrade to ShopSystems versions that address this vulnerability, as the affected versions 4.0 and earlier contain no built-in protections against such attacks. The implementation of web application firewalls and input sanitization mechanisms can provide additional layers of protection, while regular security audits and code reviews should be conducted to identify similar vulnerabilities in other components of the application. According to the mitre att&ck framework, this vulnerability would be classified under the initial access and execution techniques, specifically targeting the sql injection tactic to establish persistent access to database resources and enable further reconnaissance activities within the compromised environment.
