Description from NVD
Edito CMS restricts the ability to upload files via the UI to specific file types. However, an avatar upload functionality allows an attacker to upload files of any type and extension without restriction. This issue was fixed in version 5.10.2607. Hotfixes for older versions (5.8) have also been released.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Upload endpoints and the storage behind them. The flaw sits between uploaded content and the servers that store or serve it.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between uploaded content and the servers that store or serve it. An attacker who crosses it can place a file the server will run or serve to others.
Questions to answer about your own systems
- Where does Edito CMS run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
