Censys is aware that on March 18, 2024 Ivanti published CVE-2023-41724, a remote code execution (RCE) vulnerability in its Standalone Sentry product. This CVE was updated on March 25, 2024. According to Dark Reading, the vulnerability “allows an unauthenticated attacker to execute arbitrary code on the underlying operating system.”


Standalone Sentry, according to Ivanti, helps manage access to various organizational assets by interacting with backend enterprise resources. This level of privilege and access makes Sentry a valuable target in that it can provide opportunities for lateral movement within an organization. This concern is arguably lessened since “Threat actors without a valid TLS client certificate enrolled through EPMM / N-MDM cannot directly exploit this issue on the Internet,” (Ivanti).
However, publicly-exposed Standalone Sentry assets may serve as attractive targets for possible attackers.

According to Ivanti, ”this vulnerability impacts all supported versions 9.17.0, 9.18.0, and 9.19.0. Older versions are also at risk.”
