The CVE-2013-7074 vulnerability represents a significant cross-site scripting flaw affecting the TYPO3 content management system across multiple version branches. This vulnerability specifically targets the Content Editing Wizards functionality within TYPO3, which serves as a critical administrative interface for content creators and system administrators. The flaw exists in versions 4.5.x prior to 4.5.32, 4.7.x prior to 4.7.17, 6.0.x prior to 6.0.12, 6.1.x prior to 6.1.7, and development versions of 6.2, creating a widespread impact across the TYPO3 ecosystem. The vulnerability stems from insufficient input validation and output encoding mechanisms within the wizard interfaces that handle user-supplied parameters.
The technical implementation of this vulnerability allows authenticated attackers with access to TYPO3's administrative interface to inject malicious scripts into the system. The unspecified parameters mentioned in the description suggest that multiple entry points within the Content Editing Wizards are susceptible to manipulation. This type of vulnerability falls under CWE-79, which specifically addresses Cross-Site Scripting flaws in software applications. The attack vector requires authentication, meaning that an attacker must already possess valid credentials to exploit this vulnerability, though this does not diminish its severity given that administrative access provides extensive system control capabilities.
The operational impact of CVE-2013-7074 extends beyond simple script injection, as it can enable attackers to perform various malicious activities within the compromised TYPO3 environment. Successful exploitation could allow attackers to steal session cookies, redirect users to malicious websites, modify content displayed to other users, or even escalate privileges within the system. The vulnerability's presence in multiple version branches indicates a fundamental flaw in the input sanitization process that was not properly addressed across the TYPO3 codebase. This widespread nature suggests that organizations running any of these affected versions are at risk of having their administrative interfaces compromised, potentially leading to full system takeover or data exfiltration.
Security practitioners should note that this vulnerability aligns with ATT&CK technique T1059.007, which covers the use of scripting languages for execution. The remediation approach involves applying the official patches released by TYPO3 for each affected version line, specifically upgrading to versions 4.5.32, 4.7.17, 6.0.12, and 6.1.7 respectively. Organizations should also implement additional defensive measures including strict input validation, output encoding, and regular security audits of administrative interfaces. The vulnerability demonstrates the critical importance of maintaining up-to-date software versions and implementing proper access controls, as the authenticated nature of the attack means that any compromised administrative account could be immediately exploited to compromise the entire system.
