A type confusion vulnerability exists in the way Foxit Reader 12.1.2.15356 handles field value properties. A specially crafted Javascript code inside a malicious PDF document can trigger this vulnerability, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

An arbitrary file creation vulnerability exists in the Javascript exportDataObject API of Foxit Reader 12.1.3.15356 due to mistreatment of whitespace characters. A specially crafted malicious file can create files at arbitrary locations, which can lead to arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A code execution vulnerability exists in the Javascript saveAs API of Foxit Reader 12.1.3.15356. A specially crafted malformed file can create arbitrary files, which can lead to remote code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15356 handles a signature field. A specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

An arbitrary file creation vulnerability exists in the Javascript exportDataObject API of Foxit Reader 12.1.3.15356 due to a failure to properly validate a dangerous extension. A specially crafted malicious file can create files at arbitrary locations, which can lead to arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially-crafted malicious site if the browser plugin extension is enabled.

A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15356 handles 3D annotations. A specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

An Uncontrolled Search Path Element in Foxit Software released Foxit Reader v11.2.118.51569 allows attackers to escalate privileges when searching for DLL libraries without specifying an absolute path.

An issue was discovered in Foxit Reader and PhantomPDF before 10.1.4. It allows SQL Injection via crafted data at the end of a string.

An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It mishandles situations in which an array size (derived from a /Size entry) is smaller than the maximum indirect object number, and thus there is an attempted incorrect array access (leading to a NULL pointer dereference, or out-of-bounds read or write).

An issue was discovered in Foxit Reader and PhantomPDF before 10.1.4. It allows writing to arbitrary files because a CombineFiles pathname is not validated.
