CVE-2022-31604

CWE-502Published: July 1, 2022· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

NVFLARE, versions prior to 2.1.2, contains a vulnerability in its PKI implementation module, where The CA credentials are transported via pickle and no safe deserialization. The deserialization of Untrusted Data may allow an unprivileged network attacker to cause Remote Code Execution, Denial Of Service, and Impact to both Confidentiality and Integrity.

Risk Analysis

A vulnerability in the NVFLARE PKI module involves the unsafe deserialization of credentials transported via pickle. This critical flaw allows remote attackers to execute arbitrary code, warranting immediate attention.

There is no public exploit known, and the vulnerability is not in CISA KEV. It is remotely exploitable with low attack complexity.

Recommended Action

Upgrade to NVFLARE version 2.1.2 or higher to resolve the insecure deserialization issue.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2022-31604 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
