Why this priority: Medium severity, with no exploitation signal.
Published · Updated · NVD status: Received
What it is
The XML parser resolves external entities, so a crafted document can read local files or reach internal hosts.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker read local files or reach internal hosts through the parser.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade Progress Software Telerik Reporting to 20.3.26.1110 or later.
- Until it is patched, review who holds accounts that can reach it.
Description from NVD
In Progress® Telerik® Reporting prior to version 20.3.26.1110, improper restriction of XML external entity references in the SVG processing engine allows an authenticated attacker with low privileges who can supply SVG content to a report to read local or UNC files, or trigger server-side network requests, from the report rendering host. External XML entities in SVG content were resolved without applying the configured strict resource resolver and report path validation. Disclosed content is limited by the permissions of the rendering process and by what the rendered report output exposes.
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
- XML and document parsers in APIs and import features. The flaw sits between uploaded or posted documents and the service parsing them.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between uploaded or posted documents and the service parsing them. An attacker who crosses it can read local files or reach internal hosts through the parser.
Questions to answer about your own systems
- Where does Progress Software Telerik Reporting 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?
