CVE-2000-0254 is a medium severity vulnerability affecting version 3.0.4 of the Dansie shopping cart application, specifically in the cart.pl script. This vulnerability allows remote attackers to retrieve sensitive information from the shopping cart database and configuration files by crafting a URL that references certain form variables such as 'env', 'db', or 'vars'. Because the application fails to properly restrict access to these variables, an attacker can remotely access and download the shopping cart's internal data, including database connection details and configuration parameters. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, and the attack complexity is low. The impact is primarily on confidentiality, as attackers can obtain sensitive data that could facilitate further attacks, such as database compromise or unauthorized access to customer information. However, the vulnerability does not affect data integrity or availability directly. No patch is available for this vulnerability, and there are no known exploits in the wild documented. Given the age of this vulnerability (published in 2000), it is likely that modern systems have moved away from this software or have implemented mitigations, but legacy systems may still be at risk.

For European organizations, the primary impact is the potential exposure of sensitive customer and business data stored within the Dansie shopping cart application. Confidentiality breaches could lead to the leakage of customer personal information, payment details, or business-critical configuration data, which could result in reputational damage, regulatory penalties under GDPR, and financial loss. Although the vulnerability does not directly affect system integrity or availability, the disclosed information could be leveraged by attackers to conduct further attacks, such as database intrusion or privilege escalation. Organizations still using legacy e-commerce platforms like Dansie shopping cart 3.0.4, particularly in sectors with sensitive customer data such as retail and e-commerce, are at risk. Given the lack of patches, these organizations face a persistent risk unless mitigations are applied. The GDPR framework in Europe imposes strict requirements on protecting personal data, so exploitation of this vulnerability could lead to compliance issues and fines.

Since no official patch is available for this vulnerability, European organizations should consider the following specific mitigation steps: 1) Immediately audit and identify any systems running Dansie shopping cart version 3.0.4 or earlier. 2) Restrict external access to the cart.pl script and related URLs by implementing strict web server access controls, such as IP whitelisting or network segmentation, to limit exposure only to trusted internal networks. 3) Employ web application firewalls (WAFs) with custom rules to detect and block requests attempting to access the 'env', 'db', or 'vars' parameters. 4) If possible, upgrade or migrate to a modern, supported e-commerce platform that receives security updates. 5) Review and rotate any database credentials or sensitive configuration information that may have been exposed. 6) Monitor web server logs for suspicious access patterns targeting these variables. 7) Implement strict input validation and URL parameter filtering at the application or web server level to prevent unauthorized parameter access. These targeted mitigations go beyond generic advice by focusing on access control, monitoring, and compensating controls given the absence of a patch.
