Editing an OptoScript block containing a long string literal without spaces may cause PAC Control to crash
PAC Control Basic
PAC Control Professional
All versions through R10.a
Resolved In Version:
PAC Control may crash when you try to edit an OptoScript block containing a string literal that is longer than 63 characters and has no spaces. This may happen regardless of whether the OptoScript block is a chart or a subroutine.
This issue presents a stack-based overflow vulnerability that can be exploited by an attacker to remotely execute code on the target PC using a maliciously crafted PAC Control strategy.
NCCIC has assigned CVE-2018-04154 to identify this vulnerability.
Opto 22 has resolved this issue.
