Ntpd Driver: Exposure of Resource to Wrong Sphere
CVE-2022-48198 is a critical-severity exposure of resource to wrong sphere vulnerability in Ntpd Driver from Ntpd Driver Project, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 1.3.0, 2.2.0 as the first without the flaw, so updating Ntpd Driver to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.16% chance of exploitation within 30 days, higher than 68% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Ntpd Driver to 1.3.0 or 2.2.0, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions

|---|---|---|---|
| Ntpd Driver Project | Ntpd Driver | before 1.3.0; 2.0.0 up to, but not including, 2.2.0 | 1.3.0, 2.2.0 |

Official description
The ntpd_driver component before 1.3.0 and 2.x before 2.2.0 for Robot Operating System (ROS) allows attackers, who control the source code of a different node in the same ROS application, to change a robot's behavior. This occurs because a topic name depends on the attacker-controlled time_ref_topic parameter.
