CVE-2024-23692: Rejetto HTTP File Server 2.3m Unauthenticated RCE
Rejetto HTTP File Server, up to and including version 2.3m, is vulnerable to a template injection vulnerability. This vulnerability allows a remote, unauthenticated attacker to execute arbitrary commands on the affected system by sending a specially crafted HTTP request. As of the CVE assignment date, Rejetto HFS 2.3m is no longer supported.
Security readout for executives and security teams
Plain-English summary
Rejetto HTTP File Server 2.3m and earlier can let an unauthenticated remote attacker run commands on the host through a crafted web request. Successful exploitation could expose, alter, or destroy data and disrupt operations. The affected release is unsupported, increasing remediation urgency.
Executive priority
Treat this as an immediate remediation and incident-hunting priority. Focus first on internet-facing installations, then internal instances. Because exploitation is documented and the affected release is unsupported, replacement or retirement should take precedence over reliance on an unconfirmed patch.
Technical view
CVE-2024-23692 is a CWE-1336 template-injection vulnerability reachable over the network without credentials or user interaction. The supplied CVSS 3.1 score is 9.8, with high confidentiality, integrity, and availability impact. The CVE narrative identifies versions through 2.3m as vulnerable.
Likely exposure
Organizations operating Rejetto HFS 2.3m or earlier are potentially exposed, especially where the service accepts traffic from untrusted networks. Internal instances also present lateral-movement risk. The bundle’s structured affected-version entry conflicts with its narrative, so asset owners should confirm versions manually.
Exploitation context
CISA lists CVE-2024-23692 in its Known Exploited Vulnerabilities catalog, supporting active exploitation in the wild. Public technical analysis and Metasploit-related issue tracking also exist. No authentication or user action is required according to the supplied vulnerability description and CVSS vector.
Researcher notes
The narrative scope is HFS through 2.3m, but the supplied structured affected record contains version "0" with defaultStatus "unaffected." Treat this as a data-quality conflict rather than evidence excluding 2.3m. The bundle establishes command execution and exploitation, but provides no request indicators, patch version, or detailed vendor remediation.
Mitigation direction
Identify and retire Rejetto HFS 2.3m and earlier installations because the affected release is unsupported.
Until retirement, disable external access and restrict connectivity to explicitly authorized systems.
Check current Rejetto or trusted vendor guidance; the supplied bundle does not identify a supported patch.
Isolate suspected hosts and rotate exposed credentials if investigation finds compromise indicators.
Validation and detection
Inventory systems and services for Rejetto HFS, recording exact installed versions.
Confirm no HFS 2.3m or earlier instance is reachable from untrusted networks.
Review web, process, and EDR telemetry for unusual requests followed by command execution.
After remediation, verify the vulnerable service is removed or isolated as intended.
