Remote code execution via crafted shell script

Published Aug 1, 2023 · Updated Aug 2, 2024

Command injection in Chromad in Google Chrome on ChromeOS before 115.0.5790.131 allows remote attackers to execute arbitrary code. Chromad insufficiently validates an untrusted crafted shell script before execution; public records do not identify the affected function or validation rule. Exploitation requires user interaction and runs code with the privileges available to the affected ChromeOS component.
