CVE-2024-28213
Published: 07 March 2024
Summary
CVE-2024-28213 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Naver Ngrinder. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 7.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
nGrinder versions prior to 3.5.9 contain a deserialization flaw (CWE-502) that accepts serialized Java objects from remote, unauthenticated sources. The affected component is the application's network-facing object-handling logic, which performs unsafe deserialization without authentication or type validation, resulting in a CVSS 3.1 score of 9.8.
An unauthenticated attacker can send a crafted serialized object over the network to trigger arbitrary code execution. Successful exploitation grants the attacker full control over the confidentiality, integrity, and availability of the nGrinder instance, as indicated by the high impact metrics across all three categories.
The EPSS score has remained flat at 0.0812 with no material increase after disclosure. The version string in the CVE record indicates that upgrading to nGrinder 3.5.9 or later addresses the issue by eliminating acceptance of unauthenticated serialized objects.

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.
