CVE-2023-22496 (GCVE-0-2023-22496)

Vulnerability from cvelistv5 – Published: 2023-01-14 00:59 – Updated: 2025-03-10 21:23

Title

Netdata vulnerable to command injection

Summary

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 vulnerabilities in the system, as that user. The problem has been fixed in: Netdata agent v1.37 (stable) and Netdata agent v1.36.0-409 (nightly). As a workaround, streaming is not enabled by default. If you have previously enabled this, it can be disabled. Limiting access to the port on the recipient Agent to trusted child connections may mitigate the impact of this vulnerability.

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 vulnerabilities in the system, as that user.

Un atacante con la capacidad de establecer una conexi\u00f3n de transmisi\u00f3n puede ejecutar comandos arbitrarios en el agente Netdata objetivo. Cuando se activa una alerta, se llama a la funci\u00f3n `health_alarm_execute`. Esta funci\u00f3n realiza diferentes comprobaciones y luego pone en cola un comando llamando a `spawn_enq_cmd`. Este comando se completa con varios argumentos que no est\u00e1n sanitizados. Uno de ellos es el `registry_hostname` del nodo para el cual se genera la alerta. Al proporcionar un `registry_hostname` especialmente manipulado como parte de los datos de estado que se transmiten a un agente Netdata (principal), un atacante puede ejecutar comandos arbitrarios en el host remoto como efecto secundario de la alerta generada. Tenga en cuenta que los comandos se ejecutan como el usuario que ejecuta Netdata Agent. Este usuario suele denominarse \"netdata\". La capacidad de ejecutar comandos arbitrarios puede permitir a un atacante escalar privilegios escalando otras vulnerabilidades en el sistema, como ese usuario. El problema se solucion\u00f3 en: Netdata Agent v1.37 (estable) y Netdata Agent v1.36.0-409 (todas las noches). Como workaround, la transmisi\u00f3n en streaming no est\u00e1 habilitada de forma predeterminada. Si ha habilitado esto anteriormente, puede deshabilitarlo. Limitar el acceso al puerto del Agente destinatario a conexiones secundarias confiables puede mitigar el impacto de esta vulnerabilidad."

              "value": "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 vulnerabilities in the system, as that user. The problem has been fixed in: Netdata agent v1.37 (stable) and Netdata agent v1.36.0-409 (nightly). As a workaround, streaming is not enabled by default. If you have previously enabled this, it can be disabled. Limiting access to the port on the recipient Agent to trusted child connections may mitigate the impact of this vulnerability."
