The version of Foxit PDF Editor for Mac (previously named Foxit PhantomPDF for Mac) installed on the remote macOS host is prior to 11.0.1. It is, therefore, affected by multiple vulnerabilities:
Multiple remote code execution vulnerabilities exist in Foxit PDF Editor due to use-after-free errors when handling certain Javascripts. An unauthenticated, remote attacker can exploit these, by convincing a user to open a malicious file or visit a malicious site with the browser plugin extension enabled, to cause execute arbitrary code in the context of the current user. (CVE-2021-21831, CVE-2021-34832)
A remote code execution vulnerability exists in Foxit PDF Editor due to a use-after-free error when handling certain form elements. An unauthenticated, remote attacker can exploit this, by convincing a user to open a malicious file or visit a malicious site with the browser plugin extension enabled, to execute arbitrary code in the context of the current user. (CVE-2021-21893)
A remote code execution vulnerability exists in Foxit PDF Editor due to a use-after-free error in handling certain annotation objects. An unauthenticated, remote attacker can exploit this, by convincing a user to open a malicious file or visit a malicious site with the browser plugin extension enabled, to execute arbitrary code in the context of the current user. (CVE-2021-34846)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
