The CVE-2012-1075 vulnerability represents a critical sql injection flaw within the rtg_files extension for TYPO3 content management system versions prior to 1.5.2. This vulnerability exposes the system to remote code execution attacks where malicious actors can manipulate database queries through unsanitized input parameters. The issue specifically affects the documents download functionality, making it a targeted attack vector for adversaries seeking to compromise TYPO3 installations running vulnerable versions of this extension.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the rtg_files extension's database query construction process. When users interact with the documents download feature, the extension fails to properly escape or filter user-supplied data before incorporating it into sql statements. This allows attackers to inject malicious sql fragments that can alter the intended query behavior, potentially enabling data extraction, modification, or deletion operations. The vulnerability operates at the application layer and leverages the inherent trust placed in user inputs by the web application.
From an operational perspective, this vulnerability creates significant risk for organizations using TYPO3 systems with the affected extension. Remote attackers can exploit this weakness to gain unauthorized access to database contents, potentially obtaining sensitive information including user credentials, system configurations, and business data. The attack surface is particularly concerning as it affects the core document management functionality that many organizations rely upon for content distribution. The vulnerability's exploitation requires minimal technical skill, making it attractive to threat actors across the spectrum from script kiddies to sophisticated adversaries.
Organizations should immediately upgrade to TYPO3 version 1.5.2 or later where this vulnerability has been addressed through proper input validation and parameterized query implementation. Security patches typically involve implementing proper sql escaping mechanisms and input sanitization routines that prevent malicious data from altering query execution paths. Additionally, implementing web application firewalls and database activity monitoring can provide additional layers of protection. The vulnerability aligns with CWE-89 sql injection weakness classification and represents a common attack pattern documented in the mitre ATT&CK framework under the execution and privilege escalation techniques. Regular security assessments and input validation testing should be conducted to prevent similar vulnerabilities in other extensions and custom code implementations within the TYPO3 ecosystem.
