Security readout for executives and security teams
Plain-English summary
This vulnerability let a logged-in TYPO3 editor upload a PHP file where file extension checks should have blocked it. If successful, the editor could run arbitrary PHP code on the site. The issue is old and version-specific, but it is serious for any remaining TYPO3 6.0.x or 6.1.x deployment.
Executive priority
Treat this as high priority only if legacy TYPO3 6.0 or 6.1 systems remain in use. The business risk is site compromise by an authenticated editor account, including compromised or overprivileged accounts.
Technical view
CVE-2013-4250 affects TYPO3 6.0.x before 6.0.8 and 6.1.x before 6.1.3. The file upload component and File Abstraction Layer did not properly validate file extensions, allowing remote authenticated editors to upload PHP files and execute arbitrary PHP code.
Likely exposure
Exposure is likely limited to legacy TYPO3 sites running the affected 6.0.x or 6.1.x branches with authenticated editor accounts. The provided sources do not identify other affected products or branches.
Exploitation context
The source states exploitation requires a remote authenticated editor. The bundle does not include evidence of active exploitation, public exploit use, or CISA KEV listing, so active exploitation should not be assumed.
Researcher notes
The available evidence is concise: improper extension validation in upload and FAL paths enables authenticated editor PHP upload and execution. No CVSS, CWE, exploit-status detail, or broader product matrix is provided in the source bundle.
Mitigation direction
- Upgrade TYPO3 6.0.x installations to 6.0.8 or later.
- Upgrade TYPO3 6.1.x installations to 6.1.3 or later.
- Review the TYPO3 advisory for any branch-specific upgrade guidance.
- Prioritize migration if the affected branch is still internet-facing.
Validation and detection
- Inventory TYPO3 instances and confirm exact core versions.
- Check whether any instance runs TYPO3 6.0.x before 6.0.8.
- Check whether any instance runs TYPO3 6.1.x before 6.1.3.
- Review editor accounts with upload capability on affected systems.
- Inspect historical uploaded files for unexpected PHP content.
