The SaveDoc method in the All_In_The_Box.AllBox ActiveX control in ALL_IN_THE_BOX.OCX in Synactis ALL In-The-Box ActiveX 3 allows remote attackers to create and overwrite arbitrary files via an argument ending in a '\0' character, which bypasses the intended .box filename extension, as demonstrated by a C:\boot.ini\0 argument.

Synactis PDF In-The-Box ConnectToSynactic Stack-Based Buffer Overflow

A stack-based buffer overflow vulnerability exists in Synactis PDF In-The-Box ActiveX control (PDF_IN_1.ocx), specifically the ConnectToSynactis method. When a long string is passed to this method—intended to populate the ldCmdLine argument of a WinExec call—a strcpy operation overwrites a saved TRegistry class pointer on the stack. This allows remote attackers to execute arbitrary code in the context of the user by enticing them to visit a malicious webpage that instantiates the vulnerable ActiveX control. The vulnerability was discovered via its use in third-party software such as Logic Print 2013.
