Code execution via malformed DPAX or CMT files
Published Apr 30, 2024 · Updated Sep 3, 2024
Stack-based buffer overflow in Delta Electronics CNCSoft-G2 2.0.0.5 and earlier allows attackers to execute code via crafted DPAX or CMT files. DOPSoft's DPAX and CMT parsers copy attacker-controlled file data into fixed-length stack buffers without first validating its length. Exploitation requires a target to visit a malicious page or open a malicious file and runs code with the current process's privileges.
