Security readout for executives and security teams
Plain-English summary
CVE-2011-4902 is an old TYPO3 core issue where a remote attacker could delete arbitrary files on the webserver. For businesses, the main risk is website disruption, data integrity loss, or forced recovery work if legacy TYPO3 remains exposed.
Executive priority
Prioritize remediation if any legacy TYPO3 instance is still reachable. The issue is old, but remote arbitrary file deletion can create real outage and recovery risk.
Technical view
The CVE record says TYPO3 before 4.3.12, 4.4.x before 4.4.9, and 4.5.x before 4.5.4 allow remote arbitrary file deletion on the webserver. The bundle does not provide CVSS, CWE, exploit prerequisites, or detailed attack conditions.
Likely exposure
Exposure is most likely on legacy, internet-facing TYPO3 sites running affected versions, especially unsupported deployments that missed 2011 security updates.
Exploitation context
The provided sources describe remote attack potential, but do not confirm active exploitation. The CVE is not listed as KEV in the bundle.
Researcher notes
Evidence is limited to CVE metadata, Debian tracker, and TYPO3 advisory references. The bundle lacks CVSS, affected CPEs, exploit details, and precise vulnerable component information beyond the advisory anchor.
Mitigation direction
- Upgrade TYPO3 to a fixed or currently supported release.
- Review TYPO3-CORE-SA-2011-001 for vendor-specific remediation details.
- Apply relevant Debian package updates if TYPO3 is Debian-managed.
- Verify backups and recovery procedures for affected webserver files.
Validation and detection
- Inventory TYPO3 versions across public and internal web properties.
- Confirm no host runs before 4.3.12, 4.4.9, or 4.5.4.
- Check Debian tracker status for Debian-packaged TYPO3 instances.
- Review webserver file integrity and recent unexplained deletions.
