[原文]Untrusted search path vulnerability in day5datacopier in SGI IRIX 6.2 allows local users to execute arbitrary commands via a modified PATH environment variable that points to a malicious cp program.
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.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: disable execute permissions on the day5datacopier CGI script.
