CVE-2015-3358 in Tadaa! Module
Summary
by MITRE
Multiple open redirect vulnerabilities in the Tadaa! module before 7.x-1.4 for Drupal allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in a destination parameter, related to callbacks that (1) enable and disable modules or (2) change variables.

The CVE-2015-3358 vulnerability represents a critical open redirect flaw within the Tadaa! module for Drupal platforms, specifically affecting versions prior to 7.x-1.4. This vulnerability exploits the module's handling of destination parameters in callback functions, creating a pathway for malicious actors to manipulate user navigation. The flaw exists in the module's implementation of administrative functions that manage module enablement and disablement, as well as variable modifications, making it particularly dangerous for Drupal sites that rely on this module for administrative operations.
The technical exploitation of this vulnerability occurs through manipulation of the destination parameter within callback URLs, which are used to redirect users after performing administrative actions. When a user interacts with administrative functions such as enabling or disabling modules, or modifying system variables, the module processes a destination parameter that should ideally validate and sanitize user input. However, the vulnerability allows attackers to inject arbitrary URLs into this parameter, causing the system to redirect users to malicious sites without proper validation. This creates a vector for phishing attacks where unsuspecting users might be redirected to fraudulent websites that mimic legitimate administrative interfaces, potentially capturing credentials or other sensitive information.
The operational impact of this vulnerability extends beyond simple redirection, as it fundamentally compromises user trust and system security. Attackers can leverage this flaw to conduct sophisticated social engineering campaigns where users are unknowingly redirected to attacker-controlled domains that appear legitimate. The vulnerability affects the core administrative functionality of Drupal sites, potentially allowing attackers to gain unauthorized access to administrative interfaces or to manipulate system configurations through deceptive redirects. This type of vulnerability is particularly concerning in enterprise environments where Drupal sites manage sensitive data and administrative functions.
Security professionals should note that this vulnerability aligns with CWE-601 Open Redirect and maps to ATT&CK technique T1566.001 for credential harvesting through phishing. The flaw demonstrates poor input validation practices and inadequate sanitization of user-supplied parameters, which are fundamental security principles that should be enforced in all web applications. Organizations should prioritize immediate patching of affected systems, as the vulnerability provides attackers with a straightforward method to compromise user sessions and conduct targeted attacks. The remediation process involves upgrading to Tadaa! module version 7.x-1.4 or later, which includes proper validation and sanitization of destination parameters to prevent malicious URL injection. Additionally, administrators should implement network-level protections such as web application firewalls and monitor for suspicious redirect patterns in their systems.
