Vulnerability Information

Severity: Critical
Vulnerability Published: 2021-02-03
Patch Published: 2021-02-01
CVE [?]: CVE-2021-25274
CPE [?]: cpe:/a:solarwinds:orion_platform

Synopsis

An application running on the remote host is affected by a remote code execution vulnerability.

Description

The Collector Service in SolarWinds Orion Platform before 2019.4.2 uses MSMQ (Microsoft Message Queue) and doesn't set permissions on its private queues. As a result, remote unauthenticated clients can send messages to TCP port 1801 that the Collector Service will process. Additionally, upon processing of such messages, the service deserializes them in insecure manner, allowing remote arbitrary code execution as LocalSystem.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to SolarWinds Orion Platform 2019.4.2 or later.
