<TD width=522 colSpan=3><FONT class=regularArticle>A SECURITY
WARNING has been issued by the Computer Emergency Response Team
Coordination Center (CERT/CC) at Carnegie Mellon University advising
users of the Washington University FTP daemon (WU-FTPD) for <A
class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=Unix');">Unix</A>
and Linux systems that their <A class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/servers/servers.html?w=servers');">servers</A>
can be invaded and taken over unless patches are
installed.<BR><BR>In an announcement Thursday, CERT said the
vulnerabilities, if left open, can allow a hacker to take total
control of a computer system using remote root
capabilities.<BR><BR>Art Manion, an Internet <A class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/security/security.html?w=security');">security</A>
analyst at CERT, in Pittsburgh, said the warning was issued because
the WU-FTPD program is very popular in the <A class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=Unix');">Unix</A>
and Linux communities and has a large installed base, potentially
leaving many targets.<BR><BR>"The potential is certainly there for
it to be exploited," Manion said. <A class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=Unix');">Unix</A>
and Linux vendors, including Caldera International, Red Hat, and
SuSE Linux, have posted patches and advisories. IBM's AIX <A
class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=Unix');">Unix</A>
doesn't ship with the WU-FTPD program, so it is unaffected.
Hewlett-Packard's HP-UX <A class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=Unix');">Unix</A>
has already been patched as part of a fix for an earlier <A
class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/security/security.html?w=security');">security</A>
issue.<BR><BR>WU-FTPD is a program that provides FTP services on <A
class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=Unix');">Unix</A>
and Linux systems. The inherent vulnerabilities expose a system to
potential remote root compromise by anyone with access to the FTP
service, according to CERT.<BR><BR>The vulnerabilities involve two
shortcomings in WU-FTPD. The first is that the program doesn't
properly handle "glob" commands, which allow a user to specify
multiple file names and locations using typical shell notation.
WU-FTPD implements its own globbing code instead of using libraries
in the underlying <A class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/op_sys/op_sys.html?w=operatingsystem');">operating
system</A>. The globbing code is designed to recognize invalid
syntax and return an error condition to the calling
function.<BR><BR>But when it encounters a specific string, the
globbing code fails to properly return the error condition, creating
a hole that an intruder could attack.<BR><BR>The other vulnerability
appears when WU-FTPD is configured to use RFC 931 authentication
running in debug mode. When using RFC 931 authentication, WU-FTPD
will request ID information before authorizing a connection request
from a client. But when it's done in debugging mode, it becomes
vulnerable to attacks by any user who's able to log in, including
users with anonymous access.<BR><BR>On an unrelated note, CERT
itself has been the subject of a DoS (denial of service) attack for
the past several days, and its Web site has at times been
unreachable, the group confirmed Friday.<BR><BR>"All critical
CERT/CC functions remain operational," spokesman Bill Pollak said in
a prepared statement. "Incident and vulnerability reports are being
processed and advisories will be issued if needed. Some Internet
sites, though, may be temporarily unable to reach the CERT/CC Web
site. We are working with our service providers to resolve this
problem.<BR><BR>"The recent activity directed against the CERT/CC
Web site is not unique," Pollak said. "On a daily basis, the CERT/CC
is the target of attack attempts by intruders, and has been for many
years. The nature of the protocols and technology used for the
Internet causes organizations to be dependent on the <A
class=richlinkstyle
href="javascript:winPop('http://www.infoworld.com/klink/security/security.html?w=security');">security</A>
of others. Thus, no organization, including the CERT/CC, is
completely immune to occasional service
disruptions."<BR><BR></FONT><BR><FONT class=ArticleDate>For more
