Common Weakness Enumeration
CWE-843
AllowedAccess of Resource Using Incompatible Type ('Type Confusion')
Abstraction: Base · Status: Incomplete
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
1229 vulnerabilities reference this CWE, most recent first.
CVE-2017-14830 (GCVE-0-2017-14830)
Vulnerability from cvelistv5 – Published: 2017-12-20 14:00 – Updated: 2024-08-05 19:34

VEX
Summary
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 8.3.1.21155. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the setFocus method of XFAScriptObject objects. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this to execute code in the context of the current process. Was ZDI-CAN-5022.
Severity
No CVSS data available.

VEX
Summary
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 8.3.1.21155. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the formNodes method of XFA Node objects. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5018.
Severity
No CVSS data available.
