CVE-2017-1000490
MEDIUMCVE-2017-1000490 is a medium-severity (CVSS 6.5) Path Traversal vulnerability in mautic/core. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2017-1000490 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Mautic users able to download any files from server using filemanager
Real-World Exposure
mautic/coreReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Mautic versions 1.0.0 - 2.11.0 are vulnerable to allowing any authorized Mautic user session (must be logged into Mautic) to use the Filemanager to download any file from the server that the web user has access to.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | mautic/core | ≥ 1.0.0&&< 2.12.0 | 2.12.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mautic/core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update mautic/core to 2.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-1000490 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2017-1000490 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2017-1000490. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
