Vulnerability with Ignite on Trusted systems ------------------------------------------------------------------------- HEWLETT-PACKARD COMPANY SECURITY ADVISORY: #00111, 17 Feb 2000 ------------------------------------------------------------------------- The information in the following Security Advisory should be acted upon as soon as possible. Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Advisory as soon as possible. ------------------------------------------------------------------------- PROBLEM: Trusted systems may have vulnerabilities if a password field in /etc/passwd is blank. PLATFORM: HP-9000 Series700/800 running release HP-UX 11.X only. DAMAGE: Increase of privileges. SOLUTION: Verify that all entries in /etc/passwd have "*" in the password field if the system is trusted. ------------------------------------------------------------------------- I. A. Background Each password field in /etc/passwd should be "*" in a trusted system. This is normally handled automatically. One way for the password field to be set to a blank is to create a system image of a trusted system with Ignite-UX and not save /etc/passwd. By default Ignite-UX omits /etc/passwd. B. Fixing the problem In a trusted system if the system or the /etc/passwd file has been restored, verify that the password fields in /etc/passwd are "*". If Ignite-UX is used to create an image of a trusted system, _override_the_default_ so that /etc/passwd is saved in the image. See man(1M) make_sys_image and note the -f file option. C.
