Arbitrary memory access via unchecked CGF pointers
Published Mar 11, 2021 · Updated Aug 3, 2024
Memory corruption in Schneider Electric IGSS Definition 15.0.0.21041 and earlier allows attackers to read or write memory via a malicious CGF file. Def.exe imports attacker-controlled pointer addresses from a Configuration Group File without checking that they remain within valid buffer bounds. A user must import the crafted file; the documented consequence is arbitrary memory access in the current process.
