vulnerability alert CVE-2016-0917

EMC VNX, Celerra: NTLM authentication bypass

Synthesis of the vulnerability

An attacker can reuse secrets while running an NTLM authentication with EMC VNX and Celerra, in order to spoof a user identity.
Impacted products: EMC CAVA, EMC CEE, EMC CEPA, Celerra FAST, Celerra NS, Celerra NX4, VNX Operating Environment, VNX Series.
Severity: 3/4.
Consequences: client access/rights, data reading, data creation/edition, data deletion.
Provenance: intranet client.
Confidence: confirmed by the editor (5/5).
Creation date: 20/09/2016.
Identifiers: CVE-2016-0917, ESA-2016-096, VIGILANCE-VUL-20651.

Description of the vulnerability

The products EMC VNX and Celerra include a CIFS access.

Accessing a host via CIFS normally requires a NTLM based authentication. However, one can make VNX and Celerra use a nonce several times in the cryptographic protocol. See also VIGILANCE-VUL-9436.

An attacker can therefore reuse secrets while running an NTLM authentication with EMC VNX and Celerra, in order to spoof a user identity.

Description of the vulnerability

The bash interpreter can use functions.

However, when bash parses the source code to create the function, it directly executes commands located at some places.

This vulnerability can be used with the same attack vector than VIGILANCE-VUL-15399.

An attacker can therefore define a special environment variable, which is transmitted (via CGI or OpenSSH for example) to bash, in order to execute code.

Description of the vulnerability

The bulletin VIGILANCE-VUL-15399 describes a vulnerability of bash.

However, the offered patch (VIGILANCE-SOL-36695) is incomplete. An variant of the initial attack can thus still be used to execute code or to create a file.

In this case, the code is run when the variable is parsed (which is not necessarily an environment variable), and not when the shell starts. The impact may thus be lower, but this was not confirmed.

An attacker can therefore define a special environment variable, which is transmitted (via CGI or OpenSSH for example) to bash, in order to execute code.

Description of the vulnerability

When bash interpreter is started, environment variables of the parent process are transfered to the current process. For example:
  export A=test
  bash
  echo $A

Functions can also be transfered through environment variables. For example:
  export F='() { echo bonjour; }'
  bash
  F

However, bash loads functions by interpreting the full environment variable. If an environment variable starts with "() {" and ends with "; command", then the command is run when the shell is started.

The main attack vectors are:
 - CGI scripts (Apache mod_cgi, mod_cgid) on a web server (variables: HTTP_header, REMOTE_HOST, SERVER_PROTOCOL)
 - OpenSSH via AcceptEnv (variables : TERM, ForceCommand avec SSH_ORIGINAL_COMMAND)

An attacker can therefore define a special environment variable, which is transmitted (via CGI or OpenSSH for example) to bash, in order to execute code.

Description of the vulnerability

The OpenSSL product implements SSL/TLS, which uses a handshake.

However, by using a handshake with a ChangeCipherSpec message, an attacker can force the usage of weak keys.

An attacker can therefore act as a man in the middle between a client and a server using OpenSSL, in order to read or alter exchanged data.

Description of the vulnerability

A client based on the OpenSSL library can create an encrypted session using elliptic curves (ECDH : elliptic curves and Diffie-Hellman).

However, a malicious server can negotiate an Anonymous ECDH ciphersuite, in order to trigger a denial of service in the OpenSSL client.

An attacker, who is located on a TLS server, can therefore use Anonymous ECDH, in order to trigger a denial of service in OpenSSL client applications.

Description of the vulnerability

The ECDSA (Elliptic Curve Digital Signature Algorithm) algorithm uses a secret "k" value.

However, a local attacker can monitor the process linked to OpenSSL, and use the "FLUSH+RELOAD Cache" attack on a conditional branch (if), to obtain bit after bit the "k" secret value.

A local attacker can therefore guess the ECDSA secret used by the OpenSSL implementation, in order to obtain sensitive information.

Description of the vulnerability

The OpenSSL product uses a proprietary implementation of malloc to manage its memory.

However, when this feature is disabled with OPENSSL_NO_BUF_FREELIST, a memory area is not freed, and the ssl3_setup_read_buffer() function can, in multi-thread mode, reuse data from another SSL session.

An attacker can therefore establish a connection with a multi-threaded application linked to OpenSSL with OPENSSL_NO_BUF_FREELIST, in order to potentially inject data in the session of another user.
