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.
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 glibc library implements a DNS resolver (libresolv).

An application can thus call the getaddrinfo() function, which queries DNS servers. When the AF_UNSPEC type is used in the getaddrinfo() call, two DNS A and AAAA queries are sent simultaneously. However, this special case, and a case with AF_INET6 are not correctly managed, and lead to an overflow if the reply coming from the DNS server is larger than 2048 bytes.

An attacker, who owns a malicious DNS server, can therefore reply with large data to a client application using the getaddrinfo() function of the glibc, in order to trigger a denial of service, and possibly to run code in the client application.

Synthesis of the vulnerability

An attacker can for example send an email using a long IPv4 address, to force the messaging server to resolve this address, and to generate a buffer overflow in gethostbyname() of the glibc, in order to trigger a denial of service, and possibly to execute code.

Description of the vulnerability

The glibc library provides two functions to obtain the IP address of a server from its DNS name:
  struct hostent *gethostbyname(const char *name);
  struct hostent *gethostbyname2(const char *name, int af);

For example:
  he = gethostbyname("www.example.com");

These functions also accept to directly process an IP address:
  he = gethostbyname("192.168.1.1");

However, a malformed IPv4 address, which is too long such as 192.168.111111.1 (more than 1024 byte long) triggers an overflow in the __nss_hostname_digits_dots() function.

An attacker can therefore for example send an email using a long IPv4 address, to force the messaging server to resolve this address, and to generate a buffer overflow in gethostbyname() of the glibc, in order to trigger a denial of service, and possibly to execute code.

Several programs using the gethostbyname() function are vulnerable (exim, php, pppd, procmail) with a similar attack vector. The following programs are apparently not vulnerable: apache, cups, dovecot, gnupg, isc-dhcp, lighttpd, mariadb/mysql, nfs-utils, nginx, nodejs, openldap, openssh, postfix, proftpd, pure-ftpd, rsyslog, samba, sendmail, squid, sysklogd, syslog-ng, tcp_wrappers, vsftpd, xinetd.

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. Technical details are unknown.

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 bash interpreter can use functions.

However, when bash parses the source code to create the function, it corrupts its memory. Technical details are unknown.

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

Several vulnerabilities were announced in bash.

An attacker can force a read at an invalid address in redir_stack, in order to trigger a denial of service. [severity:1/4; CVE-2014-7186]

An attacker can generate a buffer overflow of one byte in word_lineno, in order to trigger a denial of service, and possibly to execute code. [severity:1/4; CVE-2014-7187]

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.
