Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2022-21445 is a deserialization vulnerability in the ADF Faces component of Oracle Application Development Framework within Oracle Fusion Middleware. It affects versions 12.2.1.3.0 and 12.2.1.4.0, which are obtained through the Oracle JDeveloper product. The flaw carries a CVSS 3.1 base score of 9.8 and permits remote code execution that can fully compromise the ADF runtime.

An unauthenticated attacker with network access over HTTP can exploit the issue without user interaction. Successful exploitation grants complete control over the affected ADF instance, resulting in loss of confidentiality, integrity, and availability.

Oracle's April 2022 Critical Patch Update addresses the vulnerability and directs administrators to Fusion Middleware Patch Advisor for remediation details. The CVE is also listed in CISA's Known Exploited Vulnerabilities catalog, confirming active exploitation in the wild. The associated EPSS score remains elevated near 0.92 with no material post-disclosure climb from a low baseline.

Mitigating Controls

Likely Mitigating Controls AI

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.

addresses: CWE-502

Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.

addresses: CWE-502

Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.

addresses: CWE-502

Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.

addresses: CWE-502

Validates or rejects untrusted serialized data before deserialization occurs.

addresses: CWE-502

Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.

addresses: CWE-502

Integrity verification of serialized information can detect tampering before deserialization occurs.

addresses: CWE-502

Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.

PR.PS-02 none match
prevents

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

finds

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.

prevents

Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.

finds

Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.

none

Mandatory malware scanning of data received over networks or storage media intercepts malicious serialized payloads before they are deserialized by the target application.
