CVE-2024-45398: Remote command execution through file upload in contao/core-bundle
Noroxi assessment
Priority: Monitor (action score 35/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.53% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: contao/core-bundle (Packagist) 4.13.49, 5.3.15, 5.4.3.
Low priority for now. Upgrade to contao/core-bundle (Packagist) 4.13.49, 5.3.15, 5.4.3 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
Contao is an Open Source CMS. In affected versions a back end user with access to the file manager can upload malicious files and execute them on the server. Users are advised to update to Contao 4.13.49, 5.3.15 or 5.4.3. Users unable to update are advised to configure their web server so it does not execute PHP files and other scripts in the Contao file upload directory.
