Lavawall tracks 2 published CVEs affecting RealVNC Viewer, and deploys the versions that fix them automatically across your fleet.
| CVE | Published | Severity | Details | Vector |
|---|---|---|---|---|
| CVE-2022-41975 | 2022-09-30 18:15:12 | HIGH (8) | RealVNC VNC Server before 6.11.0 and VNC Viewer before 6.22.826 on Windows allow local privilege escalation via MSI installer Repair mode. | LOCAL |
| CVE-2021-41380 | 2021-09-17 20:15:08 | MEDIUM (7) | RealVNC Viewer 6.21.406 allows remote VNC servers to cause a denial of service (application crash) via crafted RFB protocol data. NOTE: It is asserted that this issue requires social engineering a user into connecting to a fake VNC Server. The VNC Viewer application they are using will then hang, until terminated, but no memory leak occurs - the resources are freed once the hung process is terminated and the resource usage is constant during the hang. Only the process that is connected to the fake Server is affected. This is an application bug, not a security issue | NETWORK |
Why keeping RealVNC Viewer patched matters
Unpatched third-party applications are one of the most common ways attackers get in: 57% of breached MSP clients and 32% of ransomware cases trace back to a missing patch. Every RealVNC Viewer release that fixes a security bug is public, so attackers see it too, and an out-of-date install becomes a documented way in. Tracking the installed version on every machine and closing the gap quickly is what turns a disclosed CVE into a non-event.
