Critical Vulnerabilities Identified in Ivanti's Standalone Sentry and Neurons for ITSM
A critical vulnerability was discovered in Ivanti's Standalone Sentry (formerly MobileIron Sentry) and Neurons for ITSM. CVE-2023-41724 presents a flaw within the Standalone Sentry, rated at 9.6 out of 10 on the CVSS scale. The vulnerability allows attackers to remotely execute code directly onto the operating system. This effects systems running Ivanti Sentry versions 9.19 and earlier.
CVE-2023-46808 is another critical vulnerability affecting Ivanti Neurons for ITSM, scoring 9.9 out of 10 on the CVSS scale. This flaw can allow threat actors to modify files within the ITSM server. If exploited, attackers can manipulate crucial directories to further compromise the host with a sequence of malicious commands. Ivanti has announced that a patch has been deployed to all Neuron for ITSM cloud environments; however, on-premise systems would still require an immediate update.
It's worth noting that these vulnerabilities are not related to previously disclosed vulnerabilities in Ivanti's PulseSecure devices.

Recommendations
Please review your environment to ensure the above-mentioned issues are patched in a timely manner. It is security best practice to regularly update and/or patch software to the latest versions. The vulnerabilities above highlight the security benefits of limiting deployed software to "vendor-supported versions" only. This dramatically increases the likelihood that new vulnerabilities have a patch issued for them. Likewise, Cybersafe strongly encourages maintaining an inventory of current software in your environment, which helps ensure and inform your patch and vulnerability management program.
