Deeper analysis
CVE-2022-28672 is a use-after-free vulnerability (CWE-416) that affects Foxit PDF Reader version 11.2.1.53537. The flaw occurs during handling of Doc objects when the software fails to validate the existence of an object before performing operations on it, enabling arbitrary code execution in the context of the current process.
Remote attackers can exploit the issue by convincing a target to visit a malicious page or open a malicious file. Successful exploitation grants code execution without requiring elevated privileges, though user interaction is mandatory and the CVSS vector reflects local attack vector with high impact on confidentiality, integrity, and availability.
Foxit security bulletins and the corresponding Zero Day Initiative advisory ZDI-22-763 address the issue and direct users to available patches or updated builds. The EPSS score has remained near its peak of 0.2274 with a current value of 0.2202, indicating sustained but not sharply increasing exploitation interest since disclosure.
