Published: 12 December 2024
Summary
CVE-2024-11947 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Gfi Archiver. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 7.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-11947 is a deserialization of untrusted data vulnerability in the Core Service component of GFI Archiver. The affected service listens on TCP port 8017 by default and fails to properly validate user-supplied data before deserializing it, which can be abused for remote code execution. The issue was reported as ZDI-CAN-24029 and carries a CVSS 3.1 score of 8.8.
An authenticated remote attacker can send a crafted request to the Core Service and achieve arbitrary code execution with SYSTEM privileges on the host. No unauthenticated exploitation path is described.
The referenced Zero Day Initiative advisory ZDI-24-1670 provides further technical details on the flaw. The EPSS score has remained flat at 0.0855 with no observed increase after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
