Buffer overflow in SGI Omron WorldView Wnn allows remote attackers to execute arbitrary commands via long JS_OPEN, JS_MKDIR, or JS_FILE_INFO commands.

Project files may contain malicious contents which the software will use to create files on the filesystem. This allows directory traversal and overwriting files with the privileges of the logged-in user.

The Omron FINS protocol has an authenticated feature to prevent access to memory regions. Authentication is susceptible to bruteforce attack, which may allow an adversary to gain access to protected memory. This access can allow overwrite of values including programmed logic.

An attacker with network access to the affected PLC (CJ-series and CS-series PLCs, all versions) may use a network protocol to read and write files on the PLC internal memory and memory card.

Sysmac Studio installs executables in a directory with poor permissions. This can allow a locally-authenticated attacker to overwrite files which will result in code execution with privileges of a different user.
