The CVE-2015-3346 vulnerability represents a critical sql injection flaw within the WikiWiki module for Drupal platforms prior to version 6.x-1.2. This vulnerability falls under the common weakness enumeration category CWE-89 which specifically addresses sql injection vulnerabilities where untrusted data is directly incorporated into sql commands without proper sanitization or validation. The vulnerability affects the Drupal content management system and specifically targets the WikiWiki module which provides wiki functionality to Drupal sites. Attackers exploiting this vulnerability can manipulate the underlying database through specially crafted sql commands that bypass normal input validation mechanisms. The unspecified vectors mentioned in the description indicate that the vulnerability could be triggered through multiple attack paths within the module's code execution flow, potentially including user input fields, api endpoints, or parameter handling mechanisms.
The technical implementation of this vulnerability stems from improper handling of user-supplied data within the WikiWiki module's database query construction processes. When users interact with wiki pages or perform administrative functions, the module processes input data without adequate sanitization measures that would normally prevent sql injection attacks. The vulnerability allows remote attackers to execute arbitrary sql commands against the database backend, potentially enabling full database compromise, data exfiltration, or unauthorized access to sensitive information stored within the drupal installation. This type of vulnerability is particularly dangerous because it can be exploited without requiring authentication or elevated privileges, making it a significant risk for any website running vulnerable versions of the module.
The operational impact of CVE-2015-3346 extends far beyond simple data corruption or unauthorized access. Successful exploitation could result in complete database compromise, allowing attackers to extract all stored information including user credentials, content, and system configuration details. The vulnerability's remote exploitability means that attackers can target vulnerable sites from anywhere on the internet without requiring physical access or prior system compromise. This creates a substantial risk for organizations relying on drupal platforms with the affected WikiWiki module, as the attack surface is broad and the potential damage is significant. The vulnerability also represents a persistent threat since it affects older versions of the module that may not receive regular updates or patches from administrators.
Mitigation strategies for CVE-2015-3346 should prioritize immediate patching of the affected WikiWiki module to version 6.x-1.2 or later, which contains the necessary security fixes. Organizations should implement comprehensive input validation and sanitization measures throughout their web applications to prevent similar vulnerabilities from occurring in other modules or custom code. Network segmentation and access controls can help limit the potential impact of successful exploitation attempts. Regular security audits and vulnerability assessments should be conducted to identify and remediate similar issues before they can be exploited. The vulnerability aligns with ATT&CK technique T1190 which describes exploiting vulnerabilities in software applications, and represents a classic example of how insufficient input validation can lead to severe security consequences. Organizations should also consider implementing web application firewalls and database activity monitoring to detect and prevent exploitation attempts. Additionally, maintaining up-to-date security patches for all drupal modules and core platform components is essential to prevent similar vulnerabilities from compromising system integrity.
