Vulnerability in ftpd **Rev.01** ------------------------------------------------------------------------ **REVISED01** HEWLETT-PACKARD COMPANY SECURITY ADVISORY: #00117, 11 July '00 Last Revised: 12 July '00 ------------------------------------------------------------------------ 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: The ftp server (ftpd) on HP-UX allows users root access. PLATFORM: HP-UX release 11.00 - Both Problem #1 and #2 below; HP-UX release 10.20 - Problem #2, setproctitle(), only DAMAGE: Possible unauthorized root access. SOLUTION: Install temporary binary until an official patch is released. AVAILABILITY: The temporary binary is available now. CHANGE SUMMARY: Corrected typo in filename to be installed. ------------------------------------------------------------------------ I. A. Background There are 2 problems with FTP Server (ftpd) on HP-UX. 1. ftpd handling of the SITE EXEC command that allows remote users to gain root access. This is possible in the default configuration of ftpd on HP-UX 11.00 ONLY. 2. ftpd does not properly format the parameters to the setproctitle() function, allowing users to gain root access. This problem applies to both 11.00 and 10.X. B. Fixing the problem All system administrators are encouraged to install our temporary binary until an official patch is released. The file can be retrieved to simply replace the original factory supplied binary. C. Recommended solution Two temporary ftpd binaries (for HP-UX 11.00 and HP-UX 10.20) can be found at: ftp://ftp.cup.hp.com/dist/networking/ftp/ftpd.11.0 ftp://ftp.cup.hp.com/dist/networking/ftp/ftpd.10.20 **Revised 01** --->>>These are to be installed in /usr/lbin/ftpd, with permissions 544.
