The Rapid7 Insight Agent (versions > 4.1.0.2) is vulnerable to a local privilege escalation attack that allows users to gain SYSTEM level control of a Windows host. Upon startup the agent service attempts to load an OpenSSL configuration file from a non-existent directory that is writable by standard users. By planting a crafted openssl.cnf file an attacker can trick the high-privilege service into executing arbitrary commands. This effectively permits an unprivileged user to bypass security controls and achieve a full host compromise under the agent’s SYSTEM level access.

Rapid7 InsightVM, Nexpose, and the Insight Agent execute discovered executables during authenticated assessment without validating file ownership, allowing a local low-privileged user to run code as the scan credential (Scan Engine) or as root/SYSTEM (Insight Agent). Fixed in Scan Engine content 1.1.3935 and Insight Agent content component 0.0.245.0.

Rapid7 Insight Agent, versions 3.0.1 to 3.1.2.34, suffer from a local privilege escalation due to an uncontrolled DLL search path. Specifically, when Insight Agent versions 3.0.1 to 3.1.2.34 start, the Python interpreter attempts to load python3.dll at "C:\DLLs\python3.dll," which normally is writable by locally authenticated users. Because of this, a malicious local user could use Insight Agent's startup conditions to elevate to SYSTEM privileges. This issue was fixed in Rapid7 Insight Agent 3.1.2.35. This vulnerability is a regression of CVE-2019-5629.

Rapid7 Insight Agent, version 2.6.3 and prior, suffers from a local privilege escalation due to an uncontrolled DLL search path. Specifically, when Insight Agent 2.6.3 and prior starts, the Python interpreter attempts to load python3.dll at "C:\DLLs\python3.dll," which normally is writable by locally authenticated users. Because of this, a malicious local user could use Insight Agent's startup conditions to elevate to SYSTEM privileges. This issue was fixed in Rapid7 Insight Agent 2.6.4.

Rapid7 Insight Agent versions 3.1.2.38 and earlier suffer from a privilege escalation vulnerability, whereby an attacker can hijack the flow of execution due to an unquoted argument to the runas.exe command used by the iragent.exe component, resulting in elevated rights and persistent access to the machine. This issue was fixed in Rapid7 Insight Agent version 3.1.3.80.

Rapid7 Insight Agent token handler versions 3.2.6 and below, suffer from a Directory Traversal vulnerability whereby unsanitized input from a CLI argument flows into io.ioutil.WriteFile, where it is used as a path. This can result in a Path Traversal vulnerability and allow an attacker to write arbitrary files. This issue is remediated in version 3.3.0 via safe guards that reject inputs that attempt to do path traversal.

An eval() injection vulnerability in the Rapid7 Insight Agent beaconing logic for Linux versions could theoretically allow an attacker to achieve remote code execution as root via a crafted beacon response. Because the Agent uses mutual TLS (mTLS) to verify commands from the Rapid7 Platform, it is unlikely that the eval() function could be exploited remotely without prior, highly privileged access to the backend platform.

A key used in logging.json does not follow the least privilege principle by default and is exposed to local users in the Rapid7 Platform. This allows an attacker with local access to a machine with the logging.json file to use that key to authenticate to the platform with high privileges. This was fixed in the Rapid7 platform starting 3 April 2024 via the introduction of a restricted role and the removal of automatic API key generation on installation of an agent.

The installer certificate files in the …/bootstrap/common/ssl folder do not seem to have restricted permissions on Windows systems (users have read and execute access). For the client.key file in particular, this could potentially lead to exploits, as this exposes agent identity material to any locally authenticated standard user.

Rapid7 Insight Agent, versions prior to 3.1.3, suffer from an improper access control vulnerability whereby, the user has access to the snapshot directory. An attacker can access, read and copy any of the files in this directory e.g. assetinfo.json or fileinfo.json, leading to a loss of confidentiality. This issue was fixed in Rapid7 Insight Agent 3.1.3.
