What it is
The record does not classify the weakness yet; the description below says what the reporter found.
How it is reached
An attacker can exploit it over the network, with an administrator account, but someone has to act first, such as opening a file or following a link.
What an attacker gains
A successful attack can read the data it protects. The damage can spread past the vulnerable component into others.
Is it being exploited?
There is no public report of exploitation yet. EPSS estimates a 0.25% chance of exploitation activity in the next 30 days, higher than 16% of scored CVEs.
What to do
- Upgrade OpenMage magento-lts to 20.2.0 or later.
- Until it is patched, review who holds accounts that can reach it.
- Warn the people who use it, and filter files and links on the way in.
Description from NVD
OpenMage magento-lts before 20.2.0 contains a stored cross-site scripting vulnerability because the TinyMCE WYSIWYG editor fails to filter scripts in specially crafted HTML tags. Attackers can inject an img element with a malicious onmouseover attribute to execute scripts in the browsers of users viewing the rendered content.
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
- OpenMage magento-lts. Start from where it runs and what it is connected to.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- People who open files and links. Mail, chat and browsers are the delivery path.
- Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
Questions to answer about your own systems
- Where does OpenMage magento-lts 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?
