The CVE-2015-3342 vulnerability represents a critical open redirect flaw within the Ubercart Currency Conversion module for Drupal platforms, specifically affecting versions prior to 6.x-1.2. This vulnerability resides in the module's handling of URL parameters and creates a significant security risk for e-commerce websites relying on Drupal's commerce functionality. The flaw enables malicious actors to manipulate the destination query parameter in URLs, potentially redirecting users to attacker-controlled domains without their knowledge or consent.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the currency conversion module's redirect functionality. When users navigate through the currency conversion process, the module accepts a destination parameter that should ideally be validated against a whitelist of acceptable domains or properly encoded to prevent malicious redirection. The absence of proper parameter validation allows attackers to inject arbitrary URLs into the destination field, effectively bypassing the intended redirect mechanism and creating a dangerous attack vector for social engineering campaigns.
From an operational perspective, this vulnerability poses severe risks to both user trust and organizational security posture. Attackers can exploit this flaw to conduct sophisticated phishing attacks by redirecting users to malicious domains that mimic legitimate banking or e-commerce sites, potentially stealing sensitive authentication credentials or financial information. The impact extends beyond immediate credential theft as it can damage brand reputation, erode customer confidence, and potentially lead to regulatory compliance violations in industries governed by data protection regulations such as pci dss or gdpr.
The vulnerability aligns with CWE-601 open redirect vulnerability classification, which specifically addresses the risk of redirecting users to untrusted domains without proper validation. This flaw also maps to several ATT&CK tactics including initial access through phishing campaigns and credential access via social engineering techniques. Organizations utilizing Drupal commerce platforms must understand that this vulnerability creates a persistent risk surface that can be exploited across multiple user sessions and transactions, making it particularly dangerous for high-traffic e-commerce environments.
Mitigation strategies for CVE-2015-3342 require immediate patching of the affected Ubercart Currency Conversion module to version 6.x-1.2 or later, which includes proper input validation and sanitization mechanisms. Organizations should implement comprehensive network monitoring to detect unusual redirect patterns and establish strict domain whitelisting policies for all redirect operations. Additionally, security teams should conduct thorough vulnerability assessments of all Drupal modules to identify similar flaws and implement proper input validation frameworks that adhere to security best practices. Regular security updates and patch management protocols become essential defensive measures to prevent exploitation of similar vulnerabilities in other components of the Drupal ecosystem.
