IRIX day5datacopier PATH Variable Arbitrary Command Execution
Local Access Required Misconfiguration
Loss of Integrity
Exploit Public

- 漏洞描述

IRIX contains a flaw that may allow a malicious user to execute arbitrary commands as the root user. The issue is triggered when a malicious user creates a trojan horse with the same name as the system program cp and manipulates the PATH environment variable to include the directory containing the trojan. The day5datacopier CGI script will execute the trojan horse because it does not use an absolute path in its call, resulting in a loss of integrity.
