Code execution via unvalidated CBZ paths
Published Apr 13, 2021 · Updated Aug 3, 2024
Path traversal in Schneider Electric C-Bus Toolkit 1.15.7 and earlier allows remote attackers to execute code through a crafted CBZ project file. The CBZ parser uses an attacker-controlled path in file operations without validating that the resolved destination remains inside the project directory. Exploitation requires the target to open the malicious file or visit a malicious page, and resulting code runs with the current user's privileges.
