Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-27363 is a remote code execution vulnerability in Foxit PDF Reader that stems from the exportXFAData method exposing a JavaScript interface capable of writing arbitrary files. The flaw, tracked as ZDI-CAN-19697 and assigned CWE-749, affects installations of the PDF reader and carries a CVSS 3.0 score of 7.8.
An attacker can exploit the issue by convincing a target to open a malicious PDF or visit a malicious page, after which arbitrary code executes in the context of the current user. No special privileges are required beyond the user interaction needed to trigger the file or page.
Public advisories from Foxit and the Zero Day Initiative are available at the referenced URLs and address the vulnerability through security bulletins.
The EPSS score has reached a current value of 0.7947 with a recorded peak of 0.8213, indicating sustained exploitation interest following disclosure.

V8.2.1
Mitigating Controls (NIST 800-53 r5) AI
Access enforcement directly stops unauthorized callers from invoking dangerous API methods or functions.
Least privilege restricts which users or processes may reach dangerous methods, limiting exposure.
Least functionality removes or disables non-essential dangerous methods from the exposed interface altogether.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege authorization directly prevents unrestricted dangerous API methods.
Secure SDLC practices stop developers from exposing dangerous functions in the first place.
Vulnerability identification processes will surface exposed dangerous methods during assessment.
Logical access controls at the network/environment layer can limit reachability of exposed functions.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
Security testing can detect exposed dangerous functions, but does not prevent their initial introduction.
Restricting privileged utility programs reduces exposure of dangerous functions, but does not eliminate the underlying weakness.
Privileged access rights limit who can invoke dangerous methods, but do not address whether the method itself should exist.
Secure development life cycle requires removal or protection of dangerous APIs during design and coding.
Application security requirements can mandate that dangerous methods are not exposed in interfaces.
Secure architecture principles discourage exposing dangerous functions, but do not guarantee their absence.
