Published: 12 September 2024
Summary
CVE-2024-29847 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Ivanti Endpoint Manager. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 1.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a deserialization of untrusted data flaw, tracked as CWE-502, that affects the agent portal component of Ivanti EPM prior to the 2022 SU6 release or the September 2024 update. It received a CVSS 3.1 base score of 9.8 reflecting network-accessible attack conditions with no required authentication or user interaction.
A remote unauthenticated attacker can send crafted serialized data to the agent portal and obtain remote code execution on the target system, resulting in full confidentiality, integrity, and availability impact.
The referenced Ivanti security advisory for EPM September 2024 directs administrators to apply the corresponding updates for both EPM 2024 and EPM 2022 releases. The associated EPSS score stands at 0.6971 with an identical recorded peak, indicating sustained exploitation interest since 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.
