Published: 03 May 2024
Summary
CVE-2023-50223 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Inductiveautomation Ignition. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 2.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2023-50223 is a deserialization of untrusted data vulnerability in the ExtendedDocumentCodec class of Inductive Automation Ignition that permits remote code execution. The flaw stems from insufficient validation of user-supplied data during deserialization and affects installations of the Ignition platform. It carries a CVSS 3.1 base score of 8.8 and is tracked under CWE-502.
An authenticated remote attacker can supply a crafted serialized object to trigger arbitrary code execution in the context of the SYSTEM account. No user interaction is required beyond valid credentials, and the attack can be performed over the network with low complexity.
Vendor advisories from Inductive Automation and Zero Day Initiative, referenced at the provided URLs, address the issue under ZDI-CAN-22127 and ZDI-24-018. The current EPSS score of 0.5343 with a peak of 0.5400 indicates sustained exploitation interest following 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.
