CVE-2026-113362NEC Corporation WebSAM WinShare incorrect default permissions
CVE-2026-113362 is a incorrect default permissions in NEC Corporation WebSAM WinShare, rated high (8.5 on CVSS 4.0).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Received
What it is
Files or resources are created with permissions that let others read or change them.
How it is reached
An attacker can exploit it by someone who can already run code or sign in on the machine, with an ordinary user account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker use a weak default the deployment never changed.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place NEC Corporation WebSAM WinShare runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- Limit who can run code or sign in on the hosts that run it.
Description from NVD
Improper Access Control in the program installation folder in NEC Corporation WebSAM Winshare Ver 7.5.0 and earlier (excluding Ver 7.3.3), Ver 7.6.0 and Ver 7.7.0 through 7.7.1 on Windows allows a locally authenticated low-privileged attacker to execute arbitrary code with SYSTEM privileges via a crafted DLL file that is loaded by a SYSTEM-level process.
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
- Default settings, permissions and deployment configuration. The flaw sits between the shipped defaults and a hardened deployment.
Trust boundaries in play
- Host boundary. The attacker needs a foothold on the machine first; the flaw turns a small foothold into a bigger one.
- Between the shipped defaults and a hardened deployment. An attacker who crosses it can use a weak default the deployment never changed.
Questions to answer about your own systems
- Where does NEC Corporation WebSAM WinShare run in your systems, and at which version?
- Which of those hosts also run code or users you do not fully trust?
- What can it reach once compromised: which data stores, secrets and services?
