TLS Protocol Vulnerability - CVE-2012-1870

An information disclosure vulnerability exists in TLS encryption protocol. This vulnerability affects the protocol itself and is not specific to the Windows operating system. This is an information disclosure vulnerability that allows the decryption of encrypted TLS traffic. This vulnerability primarily impacts HTTPS traffic, since the browser is the primary attack vector, and all web traffic served via HTTPS or mixed content HTTP/HTTPS is affected.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-1870.

Mitigating Factors for TLS Protocol Vulnerability - CVE-2012-1870

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • All cipher suites that do not use CBC mode are not affected.

Workarounds for TLS Protocol Vulnerability - CVE-2012-1870

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

  • Prioritize the RC4 Algorithm in server software on systems running Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2

    The attack only affects cipher suites that use symmetric encryption algorithms in CBC mode, such as AES, and does not affect the RC4 algorithm. You can prioritize the RC4 algorithm in server software in order to facilitate secure communication using RC4 instead of CBC. Refer to this MSDN article, Prioritizing Schannel Cipher Suites, to learn how to perform this operation.

    Warning The client or server with which you are communicating must support the RC4 algorithm. If support for RC4 is not available, a different cipher suite will be used if one is available, and this workaround will be ineffective.

FAQ for TLS Protocol Vulnerability - CVE-2012-1870

What is the scope of the vulnerability?
This is an information disclosure vulnerability.

What causes the vulnerability?
The vulnerability is caused by a design flaw in the TLS protocol when Cipher-block chaining (CBC) mode of operation is used.

What are TLS and SSL?
The Transport Layer Security (TLS) Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. The Secure Sockets Layer (SSL) is a predecessor of the Transport Layer Security protocol. Both TLS and SSL perform the same functions and support secure network communications using a combination of public and secret key technology.

For more information, see the TechNet article, How TLS/SSL works.

What might an attacker use the vulnerability to do?
An attacker monitoring an encrypted communication who successfully exploited this vulnerability could decrypt the intercepted encrypted traffic.

How could an attacker exploit the vulnerability?
An attacker could inject malicious code in an HTTP response or host a specially crafted website containing malicious code, forcing the browser to execute this malicious code. This code sends several requests, inside the same TLS session, to a third party HTTPS website, where cookies are sent automatically if a previous authenticated session exists. This is a required condition in order to exploit this vulnerability. The attacker needs to be able to intercept this HTTPS traffic in order to exploit this vulnerability in SSL, resulting in the possibility to decrypt portions of the encrypted traffic (for example, authentication cookies).

What systems are primarily at risk from the vulnerability?
Since the browser is the primary attack vector, any systems, such as workstations or terminal servers, that send and receive HTTPS traffic are at the most risk from this vulnerability.

What does the update do?
The update modifies the way that the Windows Secure Channel (SChannel) and the Cryptography API: Next Generation (CNG) components handle encrypted network packets.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2012-1870.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had seen examples of proof of concept code published publicly but had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.
