The CVE-2015-4613 vulnerability represents a critical SQL injection flaw within the Developer Log extension for TYPO3 content management systems. This vulnerability specifically affects versions prior to 2.11.4 and resides within the backend module of the devlog extension, creating a significant security risk for organizations utilizing TYPO3 platforms. The flaw allows remote editors with existing access credentials to execute arbitrary SQL commands against the underlying database, potentially leading to complete system compromise and unauthorized data access.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the devlog extension's backend processing mechanisms. Attackers exploiting this weakness can manipulate database queries through unspecified vectors that likely involve parameter manipulation or direct input injection into extension functions. The vulnerability operates at the database layer, where user-supplied data is not properly escaped or validated before being incorporated into SQL query structures, enabling malicious actors to inject crafted SQL statements that bypass normal access controls.
From an operational perspective, this vulnerability poses severe risks to organizations using TYPO3 platforms, particularly those with remote editor accounts that may be compromised through social engineering, credential theft, or other attack vectors. The impact extends beyond simple data theft to include potential system takeover, data manipulation, and privilege escalation within the database environment. Remote editors who can access the devlog extension backend module become potential attackers capable of executing destructive SQL commands that could alter or delete critical application data, modify user permissions, or extract sensitive information from the database.
The vulnerability aligns with CWE-89, which specifically addresses SQL injection weaknesses in software applications, and demonstrates characteristics consistent with ATT&CK technique T1071.004 for application layer protocol manipulation. Organizations should immediately implement the recommended mitigation strategies including updating to TYPO3 version 2.11.4 or later, which contains the necessary patches to address the input validation deficiencies. Additional defensive measures should include implementing robust database access controls, monitoring database query logs for suspicious activity, and conducting regular security assessments of third-party extensions. Network segmentation and principle of least privilege access controls can further reduce the potential impact of such vulnerabilities by limiting the scope of damage should exploitation occur.
