A man-in-the-middle\nattacker could use this flaw to prefix arbitrary plain text to a client's\nsession (for example, an HTTPS connection to a website). This could force\nthe server to process an attacker's request as if authenticated using the\nvictim's credentials. (CVE-2009-3555)\n\nThis update disables renegotiation in the non-default IBM JSSE2 provider\nfor the Java Secure Socket Extension (JSSE) component. The default JSSE\nprovider is not updated with this fix. Refer to the IBMJSSE2 Provider\nReference Guide, linked to in the References, for instructions on how to\nconfigure the IBM Java 2 Runtime Environment to use the JSSE2 provider by\ndefault.\n\nWhen using the JSSE2 provider, unsafe renegotiation can be re-enabled using\nthe com.ibm.jsse2.renegotiate property. Refer to the following\nKnowledgebase article for details:\nhttp://kbase.redhat.com/faq/docs/DOC-20491\n\nThis update also fixes the following bug:\n\n* the libjaasauth.so file was missing from the java-1.4.2-ibm packages for\nthe Intel Itanium architecture (.ia64.rpm). This update adds the file to\nthe packages for the Itanium architecture, which resolves this issue.\n(BZ#572577)\n\nAll users of java-1.4.2-ibm are advised to upgrade to these updated\npackages, which contain the IBM 1.4.2 SR13-FP4 Java release.

Refer to the following section that applies to your version:\n\n**Note**: Applications that require session renegotiation are inherently vulnerable to the attack. Only removal of the renegotiation requirement in the application itself will eliminate the vulnerability. If session renegotiation is disabled by any of the vulnerability mitigation steps described later, without modifying the application, client connections will be dropped. For example, IE 5.0 clients accessing applications which use SGC (Server Gated Cryptography) certificates are known to require renegotiation, and their connections would be disrupted by such a configuration.\n\n**Important**: Any mitigation action that re-enables session re-negotiation on patched vulnerable versions may re-expose your F5 system to this vulnerability. In some cases, iRule logic can be used to control this behavior. Refer to the following sections for details regarding your product and version.\n\n**BIG-IP versions 10.1.0 and later**\n\nBIG-IP versions 10.2.3 and later support the Renegotiation Indication Extension. SSL Renegotiation setting is **Enabled,** by default, in the SSL profiles, however, the system requires secure renegotiation of SSL connections. For more information, refer to SOL13512: Change in Behavior: The BIG-IP SSL profiles support the TLS Renegotiation Indication Extension.\n\nIn BIG-IP version 10.1.0, the Renegotiation setting was added to the BIG-IP Client session and Server SSL profiles as a result of ID 213308 (formerly CR132180). In versions 10.1.0 - 10.2.2, the Renegotiation setting is **Disabled **by default in the Client SSL profile. Virtual servers using a Client SSL profile with the Renegotiation setting configured to **Disabled **are protected from this vulnerability.\n\nIf necessary, you can selectively enable renegotiation using the **SSL::renegotiate** iRules command on a virtual server that has renegotiation disabled in its Client SSL profile. For example, an iRule similar to the following enables renegotiation only for clients within a single Class C subnet:\n\nwhen CLIENTSSL_HANDSHAKE priority 1 { \nif { [IP::addr [IP::client_addr] equals 192.168.222.0/24] }{ \nSSL::renegotiate enable \n} \n}\n\n**Note**: For more information, refer to the DevCentral wiki page for the [SSL::renegotiate](<https://devcentral.f5.com/wiki/iRules.ssl__renegotiate.ashx>) iRule command. A separate DevCentral login is required to access this content; you will be redirected to authenticate or register (if necessary).\n\n**BIG-IP versions 9.3.1 HF8, 9.4.8 HF2, 10.0.1 HF3, and 10.1.0 through 10.2.x**\n\nTo mitigate the vulnerability, a BIG-IP system administrator may apply iRules similar to the following to each SSL virtual server. This sample iRule uses the **SSL::renegotiate** command to disable client-side session renegotiation, which prevents the BIG-IP system from processing a secondary session renegotiation request:\n\nwhen CLIENTSSL_HANDSHAKE priority 1 { \nSSL::renegotiate disable \n}\n\nThe **&lt;enable|disable&gt;**parameter was added to the **SSL::renegotiate** command in versions 9.3.1 HF8, 9.4.8 HF2, 10.0.1 HF3, 10.1.x, and 10.2.0 as a result of ID 213305 (formerly CR132165). In versions prior to 10.1.0, all virtual servers with a Client SSL profile applied will, by default, still accept session renegotiation.\n\n**Note**: For more information, refer to the DevCentral wiki page for the [SSL::renegotiate](<https://devcentral.f5.com/wiki/iRules.ssl__renegotiate.ashx>) iRule command. A separate DevCentral login is required to access this content; you will be redirected to authenticate or register (if necessary).\n\n**BIG-IP versions 9.4.x, 9.3.x prior to 9.3.1 HF8, and 10.0.x prior to 10.0.1 HF3**\n\nTo mitigate the vulnerability in versions that do not include the **SSL::renegotiate** command, apply an iRule similar to the following to each SSL virtual server. The iRule resets the connection if client-side SSL renegotiation is attempted.\n\nwhen CLIENT_ACCEPTED { \n# initialize TLS/SSL handshake count for this connection \nset sslhandshakecount 0 \n} \nwhen CLIENTSSL_HANDSHAKE priority 1 { \n# a handshake just occurred \nincr sslhandshakecount \n# is this the first handshake in this connection? \nif { $sslhandshakecount &gt; 1 } { \n# log (rate limited) the event (to /var/log/ltm) \nlog \"\\\\[VS [IP::local_addr]:[TCP::local_port] client [IP::remote_addr]:[TCP::remote_port]\\\\]:TLS/SSL renegotiation\" \n# if not, close the clientside connection \nreject \n} \n} \n\n\n**Note**: This example was provided by F5 DevCentral poster Lupo. The original post is available at the following location:\n\n[mitigating the TLS client-initiated renegotiation MITM attack](<http://devcentral.f5.com/Default.aspx?tabid=53&forumid=5&postid=86456&view=topic>)\n\nA separate DevCentral login is required to access this content; you will be redirected to authenticate or register (if necessary).\n", "published": "2009-11-05T00:00:00", "cvss": {"score": 5.8, "vector": "AV:NETWORK/AC:MEDIUM/Au:NONE/C:NONE/I:PARTIAL/A:PARTIAL/"}, "href": "http://support.f5.com/kb/en-us/solutions/public/10000/700/sol10737.html", "cvelist": ["CVE-2009-3555"], "lastseen": "2016-05-30T21:02:08"}], "cert": [{"id": "VU:120541", "type": "cert", "title": "SSL and TLS protocols renegotiation vulnerability", "description": "### Overview\n\nA vulnerability exists in SSL and TLS protocols that may allow attackers to execute an arbitrary HTTP transaction.\n\n### Description\n\nThe Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols are commonly used to provide authentication, encryption, integrity, and non-repudiation services to network applications such as HTTP, IMAP, POP3, LDAP.

This could allow and attacker to issue HTTP requests, or take action impersonating the user, among other consequences. \n \n--- \n \n### Solution\n\nUsers should contact vendors for specific patch information. \n \n--- \n \n### Systems Affected \n\nVendor| Status| Date Notified| Date Updated \n---|---|---|--- \nBarracuda Networks| | 05 Nov 2009| 17 Dec 2009 \nDebian GNU/Linux| | 05 Nov 2009| 11 Nov 2009 \nGnuTLS| | 05 Nov 2009| 11 Nov 2009 \nHewlett-Packard Company| | 05 Nov 2009| 17 Dec 2009 \nIBM Corporation| | 05 Nov 2009| 11 Nov 2009 \nMcAfee| | 05 Nov 2009| 11 Nov 2009 \nSun Microsystems, Inc.| | 05 Nov 2009| 06 Nov 2009 \nCryptlib| | 05 Nov 2009| 11 Nov 2009 \nForce10 Networks, Inc.| | 05 Nov 2009| 22 Jul 2011 \nlibgcrypt| | 05 Nov 2009| 11 Nov 2009 \nRedback Networks, Inc.| | 05 Nov 2009| 11 Nov 2009 \nSafeNet| | 05 Nov 2009| 19 Nov 2009 \n3com Inc| | 05 Nov 2009| 05 Nov 2009 \nACCESS| | 05 Nov 2009| 05 Nov 2009 \nAlcatel-Lucent| | 05 Nov 2009| 05 Nov 2009 \nIf you are a vendor and your product is affected, [let us know](<mailto:cert@cert.org?Subject=VU%23120541 Vendor Status Inquiry>). \n \n\n\n### CVSS Metrics \n\nGroup | Score | Vector \n---|---|--- \nBase | N/A | N/A \nTemporal | N/A | N/A \nEnvironmental | N/A | N/A \n \n### References\n\n * <http://extendedsubset.com/?p=8>\n * <http://www.links.org/?p=780>\n * <http://www.links.org/?p=786>\n * <http://www.links.org/?p=789>\n * <http://blogs.iss.net/archive/sslmitmiscsrf.html>\n * <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>\n * <https://bugzilla.redhat.com/show_bug.cgi?id=533125>\n * <http://lists.gnu.org/archive/html/gnutls-devel/2009-11/msg00014.html>\n * <http://cvs.openssl.org/chngview?cn=18790>\n * <http://www.links.org/files/no-renegotiation-2.patch>\n * <http://blog.zoller.lu/2009/11/new-sslv3-tls-vulnerability-mitm.html>\n * <https://svn.resiprocate.org/rep/ietf-drafts/ekr/draft-rescorla-tls-renegotiate.txt>\n * <http://www.educatedguesswork.org/2009/11/understanding_the_tls_renegoti.html>\n\n### Credit\n\nThanks to Marsh Ray of PhoneFactor for reporting this vulnerability.

Since then, most system manufacturers have released patches to fix this flaw. Still, as of June 2011 approximately half of the systems using TLS/SSL on the Internet have not implemented the patches needed to close this security hole. This vulnerability affects the secure transport of HTTP, IMAP, SMTP, and other protocols that rely on TLS/SSL. Industry representatives and security researchers who have looked into the problem note that sites with the TLS patch may still be vulnerable to this attack, known as the TLS renegotiation Man-In-The-Middle attack (TLS Renego MITM). DigiCert is taking a proactive approach to this problem by contacting its customers to advise them of this potential vulnerability in their systems. At some point in the future, connectivity problems may occur because of server non-compliance with RFC 5746.\r\n\r\nA vulnerability in the way SSL and TLS protocols allow renegotiation requests may allow an attacker to inject plaintext into an application protocol stream. This could result in a situation where the attacker may be able to issue commands to the server that appear to be coming from a legitimate source. This issue affects SSL version 3.0 and newer and TLS version 1.0 and newer.\r\nThis vulnerability affects Web Server. \r\nDiscovered by: TLS1_SSL3_Renegotiation. \r\n\r\nAttack details\r\nJust to provide you with a brief overview, the typical TLS/SSL handshake process involves the following:\r\n\r\nclient hello (highest TLS/SSL version supported, random number, suggested ciphers, suggested compression methods and, if the client is attempting renegotiation, previous session ID)\r\nserver hello (TLS/SSL version, random number, cipher suite and compression chosen and, if server is attempting renegotiation, previous session ID)\r\nserver sends TLS/SSL certificate\r\nserver hello done\r\n\r\nclient key exchange (preMasterSecret exchange and MasterSecret calculation)\r\nclient change cipher spec\r\nclient finished (hash and MAC of previous handshake messages)\r\n\r\nserver change cipher spec\r\nserver finished\r\n\r\nGET /secure HTTP/1.1\\r\\n...\r\n\r\n(For more information, see Wikipedia's article on TLS handshakes).\r\n\r\nUsing the TLS Renego MITM vulnerability, an attacker can either form a TLS connection to the server first, before the client (for example, on a compromised machine in response to the client\u2019s attempt at connection) or can use session renegotiation to effectuate the attack. Even mutual certificate-based client authentication connections are vulnerable to the TLS Renego MITM attack. More details on how various attack scenarios play out are provided in RFC 5746 and related discussions provided here and here.\r\n\r\n\r\n\r\nThe impact of this vulnerability\r\nA remote, unauthenticated attacker may be able to inject an arbitrary amount of chosen plaintext into the beginning of the application protocol stream. This could allow and attacker to issue HTTP requests, or take action impersonating the user, among other consequences.\r\n\r\nHow to fix this vulnerability\r\n\r\nThe TLS/SSL specification in RFC 5746 applies to both full handshakes and session resumption handshakes. Because pre-existing TLS/SSL specifications required systems to ignore a ClientHello extension if they did not understand it, RFC 5746 specifies that the ClientHello either contain an empty \u201crenegotiation_info\" extension or a Signaling Cipher Suite Value (SCSV) as a pseudo cipher suite with the same semantics as an empty \"renegotiation_info\" extension. When a client receives the ServerHello, it must check to see if the server supports the \"renegotiation_info\" extension. Assuming that secure renegotiation is supported per RFC 5746, then for TLS renegotiation, the client can send the \"renegotiation_info\" extension. If the server does not respond in accordance with RFC 5746, the client MUST abort the renegotiation handshake. Similarly, if a client does not respond in accordance with RFC 5746, then the server MUST abort the renegotiation handshake.\r\n\r\nFor backward compatibility, a compliant client will be configurable for either allowing insecure renegotiation or aborting an attempt to renegotiate. However, because some TLS servers do not support renegotiation at all there will be a transition period where problems will be encountered. From a server side, if the server does not receive the \"renegotiation_info\" extension or the SCSV, then RFC 5746 specifies that the \u201csecure_renegotiation\u201d flag be set to FALSE. Thereafter, if a ClientHello for renegotiation contains an empty \u201crenegotiation_info\" extension or the SCSV, then the server MUST abort the handshake.\r\n\r\nWeb references\r\nTLS1/SSLv3 Renegotiation Vulnerability \r\nCVE-2009-3555 \r\nVU#120541 \r\n", "published": "2014-04-02T13:01:00", "cvss": {"score": 0.0, "vector": "NONE"}, "href": "https://hackerone.com/reports/5617", "cvelist": ["CVE-2009-3555"], "lastseen": "2017-01-15T19:01:07"}], "exploitdb": [{"id": "EDB-ID:10579", "type": "exploitdb", "title": "TLS Renegotiation Vulnerability PoC", "description": "TLS Renegotiation Vulnerability PoC Exploit.

By default, HTML tags like <script> and <iframe> are blocked in Seamonkey and get filtered immediately upon \r\ninsertion however, While drafting a new email message, attackers can easily bypass the current input filters by encoding their \r\npayloads with base64 encryption and using the <object> tag and insert malicious scripts / code eg. (script / frame) within the \r\nemails and send it to the victims. The exploit gets triggered once the victim decides to reply back and clicks on the `Reply` or `Forward` Buttons.\r\n\r\nAfter successfully bypassing the input filters, an attacker can inject persistent script code while writing a new email and send \r\nit to victims. Interestingly the payload gets filtered during the initial viewing mode however if the victim clicks on Reply or \r\nForward, the exploit gets executed successfully.
