Name of the Vulnerable Software and Affected Versions Fatek Automation FvDesigner (affected versions not specified)

Description The issue is related to an out-of-bounds write in the parsing of FPJ files, which can be exploited by remote attackers to execute arbitrary code on affected installations. This requires user interaction, such as visiting a malicious page or opening a malicious file. The problem stems from the lack of proper validation of user-supplied data, allowing a write past the end of an allocated data structure. An attacker can leverage this to execute code in the context of the current process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
