CVE-2020-17421
Description
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Studio Photo 3.6.6.922. 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 handling of NEF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-11194.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Foxit Studio Photo 3.6.6.922 fails to validate NEF file data, leading to a heap buffer overflow that allows remote code execution with user interaction.
Vulnerability
This vulnerability exists in Foxit Studio Photo 3.6.6.922 [2]. The flaw is within the handling of NEF (Nikon Electronic Format) files. A lack of proper validation of user-supplied data can result in a write past the end of an allocated structure, leading to a heap-based buffer overflow [2].
Exploitation
Exploitation requires user interaction – the target must visit a malicious page or open a malicious NEF file [2]. An attacker can craft a specially crafted NEF file that triggers the out-of-bounds write when parsed by Foxit Studio Photo. The attack can be delivered remotely via a web page or email attachment [2].
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process (Foxit Studio Photo) [2]. This could lead to full compromise of the user's system, including data theft, installation of malware, or further lateral movement [2].
Mitigation
As of the publication date (2021-02-09), no specific patch was released for Foxit Studio Photo 3.6.6.922 [2]. Foxit's security bulletins mention updates for their PDF products, but not for Studio Photo [1]. Users should consider upgrading to the latest version of Foxit Studio Photo if available, or avoid opening NEF files from untrusted sources. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities Catalog.
