Many holes in the Netmanager Chameleon tool suite
Description:Mostly standard overflows, but there are lots of them. Virtually every product that comes in the suite seems exploitable.
Author:arager@MCGRAW-HILL.COM
Compromise:remote attackers can likely obtain root /administrator privileges on the machines running Chameleion daemons. The clients also have serious security holes.
Vulnerable Systems:These holes are in the Windows versions, although I would be very careful about running something like thier Unix Z-mail product.
Date:4 May 1998

Overflow in lynx processing of mailto: URLs
Description:a mailto: URL with a long email address causes lynx 2.8 to crashh and can cause it to execute arbitrary code
Author:Michal Zalewski <lcamtuf@boss.staszic.waw.pl>
Compromise:remote pages can cause commands to be executed on the lynx user's machine. This can also be used to break out of restricted lynx shells.
Vulnerable Systems:Those running lynx 2.8 and probably earlier.

ID games Backdoor in quake
Description:ID software blatantly put a backdoor in Quake 1/2 and QuakeWorld including both the Linux/Solaris Quake2. RCON commands sent from the subnet 192.246.40.0/24 and containing the password "tms" are automaticly executed on the server without being logged.
Author:Mark Zielinski <markz@repsec.com>
Compromise: root (remote)
Vulnerable Systems:Those running Quake 1, QuakeWorld, Quake 2, Quake 2 Linux and Quake 2 Solaris, all versions. Thus many Windows and UNIX boxes are affected
Date:1 May 1998
Notes:Quake was always a horrible security hole, but I never thought Id would stoop to introducing an intentional backdoor to allow them access to systems running Quake. I am surprised this didn't get more publicity.

Many, many, many security holes in the Microsoft Frontpage extensions
Description:There are many horrible security holes in the Microsoft Frontpage extensions. For example, you can list all files in directories on FP enabled sites, you can download password files on many of them, and a lot of FP sites even let you UPLOAD your own password files (!).
Author:pedward@WEBCOM.COM
Compromise:Break into user accounts on a web server (remote)
Vulnerable Systems:Those running the Fronpage server extensions. Sone of the vulnerabilities are UNIX only while others also work agains WindowsNT sites.

RedHat 5 metamail hole
Description:Many mail clients, MTA's, etc. are poorly written and can interpret mail in ways that lead to security wholes. One of the bugs in this message demonstrates a way to execute arbitrary commands by sending mail to a Redhat 5 user. The bug is in metamail script processing of MIME messages.
Author:Michal Zalewski <lcamtuf@BOSS.STASZIC.WAW.PL>

Author:"Secure Networks Inc." <sni@SECURENETWORKS.COM>
Compromise:Download sensitive ascend configuration information (passwords, etc.) plus a remote DOS attack to take out the router.
Vulnerable Systems:Ascend Pipeline and MAX routers including OS release 5.0Ap42 (MAX) and 5.0A (Pipeline).

mSQL overflow and poor hostname authentication checks
Description:mSQL has several buffer overflows which allow intruders to remotely execute arbitrary code. msql2d and msqld are specific vulnerable programs. Also, mSQL doesn't do a forward lookup after resolving an IP->hostname, so it is trivial to spoof authentication by having your DNS return the hostname of an actual host.
Author:"Secure Networks Inc." <sni@SILENCE.SECNET.COM>
Compromise:run arbitrary commands remotely. Spoof access to an mSQL server.
Vulnerable Systems:Those running the mSQL server software, msqld or msql2d. Version 2.0 is vulnerable, probably earlier versions.

L0phtcrack 1.5 Lanman / NT password hash cracker
Description:The Lanman password hash is used by NT for authenticating users locally and over the network (MS service packs are now out that allow a different method in both cases). L0phtcrack can brute-force these hashes (taken from network logs or progams like pwdump) and recover the plaintext password. l0phtcrack 1.5 also breaks the new NT style password hashes.
Author:Mudge <mudge@l0pht.com>
Compromise:Compromise account passwords (remotely if you can sniff a server challenge.
Vulnerable Systems:NT 4.0, 3.51. I believe NT4 Service Pack 3 SYSKEY fix will defeat pwdump style utilities. MS also has a fix out to disable Lanman authentication over the network, but this breaks compatibility w/W95 and 3.11.
Date:12 July 1997
Notes:First comes a very interesting message from mudge about M$ "authentication", then comes the readme file for l0phtcrack 1.5. Next comes the source distribution in uuencoded form. You can get executables at their webpage, www.l0pht.com.

Glimps HTTP evil inadequate evil char filter
Description:Glips HTTP, a web interface to the Glimps search program, doesn't adequately check its input for evil characters. By tricking it to open a pipe instead of a file, you can remotely execute arbitrary commands on the server.
Author:Razvan Dragomirescu <drazvan@kappa.ro>
Compromise:Execute arbitrary commands on a server running Glimps HTTP (remote).
Vulnerable Systems:Anything running a vulnerable and unmodified version of Glimpse HTTP. Runs on most systems.
Date:2 July 1997
Notes:Razvan Dragomirescu claims that he is getting "angry" at all the idiots who send him passwd files by not modifying his example exploit. But *I* wouldn't mind! So I've modified the exploit to use my address instead of his. DON'T FORGET TO CHANGE IT!

IRIX fails to correctly patch /cgi-bin/handler exploit
Description:In an apparent attempt to prevent breakins through the common handler cgi technique, IRIX changed the code. They now check the end of a string for a pipe (trying to make sure perl opens the file as a plain file), but you can still get away with putting tabs after the pipe, to hide it.
Author:Razvan Dragomirescu <drazvan@kappa.ro>
