The VRFY buffer is overrun, as it was only designed to hold 128 bytes Stuffing 1,000 bytes into the VRFY buffer could cause a denial of service and crash the sendmail daemon; however, it is even more dangerous to have the target system execute code of your choosing This is exactly how a successful buffer overflow attack works Instead of sending 1,000 letter a s to the VRFY command, the attackers will send specific code that will overflow the buffer and execute the command /bin/sh Recall that sendmail is running as root, so when /bin/sh is executed, the attackers will have instant root access You may be wondering how sendmail knew that the attackers wanted to execute /bin/sh It s simple When the attack is executed, special assembly code known as the egg is sent to the VFRY command as part of the actual string used to overflow the buffer When the VFRY buffer is overrun, attackers can set the return address of the offending function, allowing the attackers to alter the flow of the program Instead of the function returning to its proper memory location, the attackers execute the nefarious assembly code that was sent as part of the buffer overflow data, which will run /bin/sh with root privileges Game over It is imperative to remember that the assembly code is architecture and operating system dependent A buffer overflow for Solaris X86 running on Intel CPUs is completely different from one for Solaris running on SPARC systems The following listing illustrates what an egg, or assembly code specific to Linux X86, looks like:

With this knowledge, the attackers know to look in the /var/log directory for key log files With a simple listing of that directory, we find all kinds of log files, including cron, maillog, messages, spooler, auth, wtmp, and xferlog A number of files will need to be altered, including messages, secure, wtmp, and xferlog Because the wtmp log is in binary format (and typically used only for the who command), the attackers will often use a rootkit program to alter this file Wzap is specific to the wtmp log and will clear out the specified user from the wtmp log only For example, to run logclean-ng, perform the following:

char shellcode[] = "\xeb\x1f\x5e\x89\x76\x08\x31\xc0\x88\x46\x07\x89\x46\x0c\xb0\x0b" "\x89\xf3\x8d\x4e\x08\x8d\x56\x0c\xcd\x80\x31\xdb\x89\xd8\x40\xcd" "\x80\xe8\xdc\xff\xff\xff/bin/sh";

It should be evident that buffer overflow attacks are extremely dangerous and have resulted in many security-related breaches Our example is very simplistic it is extremely difficult to create a working egg However, most system-dependent eggs have

Keep in mind that disabling stack execution is not foolproof Disabling stack execution will normally log any program that tries to execute code on the stack and tends to thwart most script kiddies However, experienced attackers are quite capable of writing (and distributing) code that exploits a buffer overflow condition on a system with stack execution disabled While people go out of their way to prevent stack-based buffer overflows by disabling stack execution, other dangers lie in poorly written code While not getting a lot of

(1921681102) (localhost) (localhost) (localhost) (1921681102) (1921681102) (1921681102) (1921681102) (1921681102) (1921681102) (1921681102) (1921681102)

attention, heap-based overflows are just as dangerous Heap-based overflows are based on overrunning memory that has been dynamically allocated by an application This differs from stack-based overflows, which depend on overflowing a fixed-length buffer Unfortunately, vendors do not have equivalent no heap execution settings Thus, you should not become lulled into a false sense of security by just disabling stack execution While not covered in detail here, more information on heap-based overflows can be found from the research the w00w00 team has performed at http://wwww00w00org/ files/heaptut/heaptuttxt

In 1996, Jennifer Myers identified and reported the infamous PHF vulnerability Although this attack is rather dated, it provides an excellent example of an input validation attack To reiterate, if you understand how this attack works, your understanding can be applied to many other attacks of the same genre even thought it is an older attack We will not spend an inordinate amount of time on this subject, as it is covered in additional detail in 15 Our purpose is to explain what an input validation attack is, and how it may allow attackers to gain access to a UNIX system An input validation attack occurs when M I I L A program fails to recognize syntactically incorrect input A module accepts extraneous input A module fails to handle missing input fields A field-value correlation error occurs
