Netdata is an open source observability tool. In affected versions the `ndsudo` tool shipped with affected versions of the Netdata Agent allows an attacker to run arbitrary programs with root permissions. The `ndsudo` tool is packaged as a `root`-owned executable with the SUID bit set. It only runs a restricted set of external commands, but its search paths are supplied by the `PATH` environment variable. This allows an attacker to control where `ndsudo` looks for these commands, which may be a path the attacker has write access to. This may lead to local privilege escalation. This vulnerability has been addressed in versions 1.45.3 and 1.45.2-169. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Netdata is an open source option for real-time infrastructure monitoring and troubleshooting. Each Netdata Agent has an automatically generated MACHINE GUID. It is generated when the agent first starts and it is saved to disk, so that it will persist across restarts and reboots. Anyone who has access to a Netdata Agent has access to its MACHINE_GUID. Streaming is a feature that allows a Netdata Agent to act as parent for other Netdata Agents (children), offloading children from various functions (increased data retention, ML, health monitoring, etc) that can now be handled by the parent Agent. Configuration is done via `stream.conf`. On the parent side, users configure in `stream.conf` an API key (any random UUID can do) to provide common configuration for all children using this API key and per MACHINE GUID configuration to customize the configuration for each child. The way this was implemented, allowed an attacker to use a valid MACHINE_GUID as an API key. This affects all users wh…

Netdata is an open source option for real-time infrastructure monitoring and troubleshooting. An attacker with the ability to establish a streaming connection can execute arbitrary commands on the targeted Netdata agent. When an alert is triggered, the function `health_alarm_execute` is called. This function performs different checks and then enqueues a command by calling `spawn_enq_cmd`. This command is populated with several arguments that are not sanitized. One of them is the `registry_hostname` of the node for which the alert is raised. By providing a specially crafted `registry_hostname` as part of the health data that is streamed to a Netdata (parent) agent, an attacker can execute arbitrary commands at the remote host as a side-effect of the raised alert. Note that the commands are executed as the user running the Netdata Agent. This user is usually named `netdata`. The ability to run arbitrary commands may allow an attacker to escalate privileges by escalating other vulnerabil…

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in NetDataSoft DivvyDrive allows Stored XSS.This issue affects DivvyDrive: from unspecified before v.4.6.2.0.

An issue was discovered in Netdata 1.10.0. HTTP Header Injection exists via the api/v1/data filename parameter because of web_client_api_request_v1_data in web/api/web_api_v1.c.

An issue was discovered in Netdata 1.10.0. JSON injection exists via the api/v1/data tqx parameter because of web_client_api_request_v1_data in web/api/web_api_v1.c.

An issue was discovered in Netdata 1.10.0. Log Injection (or Log Forgery) exists via a %0a sequence in the url parameter to api/v1/registry.

An issue was discovered in Netdata 1.10.0. Full Path Disclosure (FPD) exists via api/v1/alarms. NOTE: the vendor says "is intentional.

The Netdata web application through 1.13.0 allows remote attackers to inject their own malicious HTML code into an imported snapshot, aka HTML Injection. Successful exploitation will allow attacker-supplied HTML to run in the context of the affected browser, potentially allowing the attacker to steal authentication credentials or to control how the site is rendered to the user. NOTE: the vendor disputes the risk because there is a clear warning next to the button for importing a snapshot
