Ivanti has issued patches for two vulnerabilities. One was discovered in the Ivanti Standalone Sentry, which impacts all supported versions 9.17.0, 9.18.0, and 9.19.0. Older versions are also at risk. The other vulnerability impacts all supported versions of Ivanti Neurons for ITSM—2023.3, 2023.2 and 2023.1, as well as unsupported versions which will need an upgrade before patching.
The Common Vulnerabilities and Exposures (CVE) database lists publicly disclosed computer security flaws. The CVEs patched in these updates are:
CVE-2023-41724 (CVSS score 9.6 out of 10), which allows an unauthenticated threat actor to execute arbitrary commands on the underlying operating system of the appliance within the same physical or logical network.
This vulnerability was reported to Ivanti by the NATO Cyber Security Centre. Ivanti says it’s not aware of any customers being exploited by this vulnerability at the time of disclosure. The attack option is limited because an attacker without a valid Transport Layer Security (TLS) client certificate enrolled through Ivanti Endpoint Manager Mobile (EPMM) cannot directly exploit this issue on the internet.
Ivanti says its customers can access the patch (9.17.1, 9.18.1 and 9.19.1) via the standard download portal.
CVE-2023-46808 (CVSS score 9.9 out of 10) which allows an authenticated remote user to perform file writes to ITSM server. Successful exploitation can be used to write files to sensitive directories which may allow attackers to execute commands in the context of a web application’s user.
The patch has been applied to all Ivanti Neurons for ITSM Cloud landscapes. On-premise customers are advised to act immediately to ensure they are fully protected. Ivanti says it is not aware of any customers being exploited by this vulnerability prior to public disclosure.
The patch is available on the Ivanti Neurons for ITSM downloads page for each respective 2023.X version. This will require upgrading to 2023.X to apply the patch.
The vulnerabilities have a 2023 CVE because of a reservation made towards the end of 2023, when they were first found and reported. It is Ivanti’s policy that when a CVE is not under active exploitation to disclose the vulnerability when a fix is available, so that customers have the tools they need to protect their environment.
