CVE-2022-28684
Published: 03 August 2022
Summary
CVE-2022-28684 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Devexpress Devexpress. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 3.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
This vulnerability is a deserialization flaw (CWE-502) in the SafeBinaryFormatter library within DevExpress installations. It stems from insufficient validation of user-supplied data and carries a CVSS 3.1 score of 8.8, enabling remote code execution when successfully triggered.
Authenticated remote attackers can exploit the issue over the network to run arbitrary code in the context of the service account. No authentication bypass is involved, and the attack requires valid credentials to reach the affected component.
The issue was reported as ZDI-CAN-16710 and disclosed via Zero Day Initiative advisory ZDI-22-872, which directs users to vendor guidance for remediation. The associated EPSS score has remained flat at 0.2409 with no material increase since publication.

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.
