CVE-2023-33963
Published: 01 June 2023
Summary
CVE-2023-33963 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Dataease Dataease. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 7.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
DataEase, an open source data visualization and analysis tool, is affected by a deserialization vulnerability in its datasource component prior to version 1.18.7. Tracked as CVE-2023-33963 and mapped to CWE-502, the flaw permits arbitrary code execution and is rated 9.8 under CVSS 3.1, reflecting network-accessible attack vectors that require no authentication or user interaction.
An unauthenticated remote attacker can supply crafted serialized objects to the datasource endpoint, resulting in code execution that compromises confidentiality, integrity, and availability of the affected instance.
Advisories published with the v1.18.7 release state that the issue is resolved in that version and that no workarounds exist other than upgrading. The associated EPSS score has remained flat at 0.0811 with no material 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.
