This is a writeup about a flaw that I found recently, and that existed in multiple implementations of SMTP (Simple Mail Transfer Protocol) over TLS (Transport Layer Security) including my Postfix open source mailserver. I give an overview of the problem and its impact, how to find out if a server is affected, fixes, and draw lessons about where we can expect similar problems. A time line is at the end.

Wietse
Problem overview and impact
The TLS protocol encrypts communication and protects it against modification by other parties. This protection exists only if a) software is free of flaws, and b) clients verify the server's TLS certificate, so that there can be no "man in the middle" (servers usually don't verify client certificates).
The problem discussed in this writeup is caused by a software flaw.
The injected commands could be used to steal the victim's email or SASL (Simple Authentication and Security Layer) username and password.
This is not as big a problem as it may appear to be. The reason is that many SMTP client applications don't verify server TLS certificates. These SMTP clients are always vulnerable to command injection and other attacks. Their TLS sessions are only encrypted but not protected.
A similar plaintext injection flaw may exist in the way SMTP clients handle SMTP-over-TLS server responses, but its impact is less interesting than the server-side flaw.
SMTP is not the only protocol with a mid-session switch from plaintext to TLS. Other examples are POP3, IMAP, NNTP and FTP. Implementations of these protocols may be affected by the same flaw as discussed here.
Demonstration
The problem is easy to demonstrate with a one-line change to the OpenSSL s_client command source code (I would prefer scripting, but having to install Perl CPAN modules and all their dependencies is more work than downloading a .tar.gz file from openssl.org, adding eight characters to one line, and doing "./config; make").
The OpenSSL s_client command can make a connection to servers that support straight TLS, SMTP over TLS, or a handful other protocols over TLS. The demonstration with SMTP over TLS involves a one-line change in the OpenSSL s_client source code (with OpenSSL 1.0.0, at line 1129 of file apps/s_client.c).
Old: BIO_printf(sbio,"STARTTLS\r\n"); New: BIO_printf(sbio,"STARTTLS\r\nRSET\r\n");
With this change, the s_client command sends the plaintext STARTTLS command ("let's turn on TLS") immediately followed by an RSET command (a relatively harmless protocol "reset"). Both commands are sent as plaintext in the same TCP/IP packet, and arrive together at the server. The "\r\n" are the carriage-return and newline characters; these are necessary to terminate an SMTP command.
When an SMTP server has the plaintext injection flaw, it reads the STARTTLS command first, switches to SMTP-over-TLS mode, and only then the server reads the RSET command. Note, the RSET command was transmitted during the plaintext SMTP phase when there is no protection, but the server reads the command as if it was received over the TLS-protected channel.
Thus, when the SMTP server has the flaw, the s_client command output will show two "250" SMTP server responses instead of one. The first "250" response is normal, and is present even when the server is not flawed. The second "250" response is for the RSET command, and indicates that the SMTP server has the plaintext injection flaw.
$ apps/openssl s_client -quiet -starttls smtp -connect server:port [some server TLS certificate details omitted] 250 some text here <=== Normal response, also with "good" server. 250 more text here <=== RSET response, only with flawed server.
Anatomy of the flaw: it's all about the plumbing
Whether a program may have the plaintext injection flaw depends on how it adjusts the plumbing, as it inserts the TLS protocol layer in-between the SMTP protocol layer and the O/S TCP/IP protocol layer. I illustrate this with examples from three open source MTAs: Postfix, Sendmail and Exim. The diagram below is best viewed with a fixed-width font, for example, from the Courier family.
Postfix MTA Sendmail MTA Exim MTA
before/after before/after before/after
switch to TLS switch to TLS switch to TLS
SMTP SMTP SMTP SMTP SMTP SMTP <= SMTP layer
|| || || || || ||

As shown in the diagram, both Postfix and Sendmail use an application- level stream abstraction, where each stream has properties such as read/write buffers, read/write functions (indicated with rw), and other properties that are omitted for brevity.
When Postfix switches to SMTP over TLS, it replaces the plaintext read/write functions (rw) with the TLS read/write functions (r'w'). Postfix does not modify any of the other stream properties including the read/write buffers. A patch for qmail that introduces TLS support uses the same approach. This approach of replacing only the stream read/write functions, but not the buffers or other stream properties, can introduce the plaintext injection flaw.
When Sendmail switches to SMTP over TLS, it replaces the entire stream, along with its read/write buffers and read/write functions. Exim, on the other hand, does not seem to have a stream abstraction like Postfix, Sendmail or qmail. Instead of replacing streams or stream properties, Exim replaces plaintext read/write functions with TLS read/write functions. Because of their program structure, Sendmail and Exim didn't suffer from the plaintext injection flaw.
Fixing the problem
There are two solutions to address the flaw, and both solutions can be used together.
- Report an error when unexpected plaintext is received after the STARTTLS command. As documented in RFC 3207, STARTTLS must be the last command in a pipelined group. If plaintext commands are received after STARTTLS, then that is a protocol violation.
This measure can also be implemented outside the MTA, for example in a protocol-aware firewall.
- If a program uses the same input buffer before and after the switch to TLS, it should discard the contents of the input buffer, just like it discards SMTP protocol information that it received during the plaintext protocol phase.
Conclusion
This plaintext injection problem is likely to recur when some development moves the plaintext-to-ciphertext switch outside the application: for example, into the kernel, into the local hardware, into a proxy, or into other infrastructure. This encourages applications to use the same application-level streams and buffers and read/write functions before and after the switch to ciphertext. When this migration happens, plaintext injection becomes once more a possibility.
Time line
Jan 5 2011: While finishing Postfix for its annual release, I found and fixed this flaw in the SMTP server and client implementations, where it had been sitting ever since TLS support was adopted.
Jan 6-10 2011: As we investigated the scope of the problem, Victor Duchovni (co-developer) discovered that other implementations were also affected including security providers and security appliances.
Jan 11 2011: Contact CERT/CC to help coordinate with the problem's resolution.
Mar 7 2011: Public announcement, and Postfix legacy release updates.

This is a writeup about a flaw that I found recently, and that\nexisted in multiple implementations of SMTP (Simple Mail Transfer\nProtocol) over TLS (Transport Layer Security) including my Postfix\nopen source mailserver. I give an overview of the problem and its\nimpact, how to find out if a server is affected, fixes, and draw\nlessons about where we can expect similar problems. A time line\nis at the end. \n\nFor further reading:\nhttp://www.kb.cert.org/vuls/id/555316 \nhttp://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-0411\nhttp://www.postfix.org/CVE-2011-0411.html (extended writeup)\n\n\tWietse\n\nProblem overview and impact\n===========================\n\nThe TLS protocol encrypts communication and protects it against\nmodification by other parties. This protection exists only if a)\nsoftware is free of flaws, and b) clients verify the server\u0027s TLS\ncertificate, so that there can be no \"man in the middle\" (servers\nusually don\u0027t verify client certificates). \n\nThe problem discussed in this writeup is caused by a software flaw. \n\nThe injected commands could be used to steal the victim\u0027s email or\nSASL (Simple Authentication and Security Layer) username and password. \n\nThis is not as big a problem as it may appear to be. The reason\nis that many SMTP client applications don\u0027t verify server TLS\ncertificates. These SMTP clients are always vulnerable to command\ninjection and other attacks. Their TLS sessions are only encrypted\nbut not protected. \n\nA similar plaintext injection flaw may exist in the way SMTP clients\nhandle SMTP-over-TLS server responses, but its impact is less\ninteresting than the server-side flaw. \n\nSMTP is not the only protocol with a mid-session switch from plaintext\nto TLS. Other examples are POP3, IMAP, NNTP and FTP. Implementations\nof these protocols may be affected by the same flaw as discussed here. \n\nDemonstration\n=============\n\nThe problem is easy to demonstrate with a one-line change to the\nOpenSSL s_client command source code (I would prefer scripting, but\nhaving to install Perl CPAN modules and all their dependencies is\nmore work than downloading a .tar.gz file from openssl.org, adding\neight characters to one line, and doing \"./config; make\"). \n\nThe OpenSSL s_client command can make a connection to servers that\nsupport straight TLS, SMTP over TLS, or a handful other protocols\nover TLS. The demonstration with SMTP over TLS involves a one-line\nchange in the OpenSSL s_client source code (with OpenSSL 1.0.0, at\nline 1129 of file apps/s_client.c). \n\nOld:\t\tBIO_printf(sbio,\"STARTTLS\\r\\n\");\nNew:\t\tBIO_printf(sbio,\"STARTTLS\\r\\nRSET\\r\\n\");\n\nWith this change, the s_client command sends the plaintext STARTTLS\ncommand (\"let\u0027s turn on TLS\") immediately followed by an RSET command\n(a relatively harmless protocol \"reset\"). Both commands are sent\nas plaintext in the same TCP/IP packet, and arrive together at the\nserver. The \"\\r\\n\" are the carriage-return and newline characters;\nthese are necessary to terminate an SMTP command. \n\nWhen an SMTP server has the plaintext injection flaw, it reads the\nSTARTTLS command first, switches to SMTP-over-TLS mode, and only\nthen the server reads the RSET command. Note, the RSET command was\ntransmitted during the plaintext SMTP phase when there is no\nprotection, but the server reads the command as if it was received\nover the TLS-protected channel. \n\nThus, when the SMTP server has the flaw, the s_client command output\nwill show two \"250\" SMTP server responses instead of one. The first\n\"250\" response is normal, and is present even when the server is\nnot flawed. The second \"250\" response is for the RSET command, and\nindicates that the SMTP server has the plaintext injection flaw. \n\n $ apps/openssl s_client -quiet -starttls smtp -connect server:port\n [some server TLS certificate details omitted]\n 250 some text here \u003c=== Normal response, also with \"good\" server. \n 250 more text here \u003c=== RSET response, only with flawed server. \n\nAnatomy of the flaw: it\u0027s all about the plumbing\n================================================\n\nWhether a program may have the plaintext injection flaw depends on\nhow it adjusts the plumbing, as it inserts the TLS protocol layer\nin-between the SMTP protocol layer and the O/S TCP/IP protocol\nlayer. I illustrate this with examples from three open source MTAs:\nPostfix, Sendmail and Exim. The diagram below is best viewed with\na fixed-width font, for example, from the Courier family. \n\n Postfix MTA Sendmail MTA Exim MTA\n before/after before/after before/after\n switch to TLS switch to TLS switch to TLS\n\n SMTP SMTP SMTP SMTP SMTP SMTP \u003c= SMTP layer\n || || || || || ||\n stream stream stream stream\u0027 || ||\n buffers buffers buffers buffers\u0027 rw r\u0027w\u0027 \u003c= stream layer\n rw r\u0027w\u0027 rw r\u0027w\u0027 || ||\n || || || || || ||\n || TLS || TLS || TLS \u003c= TLS layer\n || || || || || ||\n O/S O/S O/S O/S O/S O/S \u003c= TCP/IP layer\n\nAs shown in the diagram, both Postfix and Sendmail use an application-\nlevel stream abstraction, where each stream has properties such as\nread/write buffers, read/write functions (indicated with rw), and\nother properties that are omitted for brevity. \n\nWhen Postfix switches to SMTP over TLS, it replaces the plaintext\nread/write functions (rw) with the TLS read/write functions (r\u0027w\u0027). \nPostfix does not modify any of the other stream properties including\nthe read/write buffers. A patch for qmail that introduces TLS\nsupport uses the same approach. This approach of replacing only\nthe stream read/write functions, but not the buffers or other stream\nproperties, can introduce the plaintext injection flaw. \n\nWhen Sendmail switches to SMTP over TLS, it replaces the entire\nstream, along with its read/write buffers and read/write functions. \nExim, on the other hand, does not seem to have a stream abstraction\nlike Postfix, Sendmail or qmail. Instead of replacing streams or\nstream properties, Exim replaces plaintext read/write functions\nwith TLS read/write functions. Because of their program structure,\nSendmail and Exim didn\u0027t suffer from the plaintext injection flaw. \n\nFixing the problem\n==================\n\nThere are two solutions to address the flaw, and both solutions can\nbe used together. \n\n- Report an error when unexpected plaintext is received after the\n STARTTLS command. As documented in RFC 3207, STARTTLS must be\n the last command in a pipelined group. If plaintext commands are\n received after STARTTLS, then that is a protocol violation. \n\n This measure can also be implemented outside the MTA, for example\n in a protocol-aware firewall. \n\n- If a program uses the same input buffer before and after the\n switch to TLS, it should discard the contents of the input buffer,\n just like it discards SMTP protocol information that it received\n during the plaintext protocol phase. \n\nConclusion\n==========\n\nThis plaintext injection problem is likely to recur when some\ndevelopment moves the plaintext-to-ciphertext switch outside the\napplication: for example, into the kernel, into the local hardware,\ninto a proxy, or into other infrastructure. This encourages\napplications to use the same application-level streams and buffers\nand read/write functions before and after the switch to ciphertext. \nWhen this migration happens, plaintext injection becomes once more\na possibility. \n\nTime line\n=========\n\nJan 5 2011: While finishing Postfix for its annual release, I found\nand fixed this flaw in the SMTP server and client implementations,\nwhere it had been sitting ever since TLS support was adopted. \n\nJan 6-10 2011: As we investigated the scope of the problem, Victor\nDuchovni (co-developer) discovered that other implementations were\nalso affected including security providers and security appliances. \n\nJan 11 2011: Contact CERT/CC to help coordinate with the problem\u0027s\nresolution. \n\nMar 7 2011: Public announcement, and Postfix legacy release updates. \n \n Packages for 2009.0 are provided as of the Extended Maintenance\n Program.
