Summary

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Pluggable Auth). Supported versions that are affected are 5.6.35 and earlier and 5.7.17 and earlier. Easily "exploitable" vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 7.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). NOTE: the previous information is from the April 2017 CPU. Oracle has not commented on third-party claims that this issue is an integer overflow in sql/auth/sql_authentication.cc which allows remote attackers to cause a denial of service via a crafted authentication packet.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

    descriptionThe version of MySQL running on the remote host is 5.6.x prior to 5.6.36. It is, therefore, affected by multiple vulnerabilities : - A carry propagation error exists in the OpenSSL component in the Broadwell-specific Montgomery multiplication procedure when handling input lengths divisible by but longer than 256 bits. This can result in transient authentication and key negotiation failures or reproducible erroneous outcomes of public-key operations with specially crafted input. A man-in-the-middle attacker can possibly exploit this issue to compromise ECDH key negotiations that utilize Brainpool P-512 curves. (CVE-2016-7055) - An authentication information disclosure vulnerability, known as Riddle, exists due to authentication being performed prior to security parameter verification. A man-in-the-middle (MitM) attacker can exploit this vulnerability to disclose sensitive authentication information, which the attacker can later use for authenticating to the server. (CVE-2017-3305) - Multiple unspecified flaws exist in the DML subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3308, CVE-2017-3456) - Multiple unspecified flaws exist in the Optimizer subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3309, CVE-2017-3452, CVE-2017-3453) - An unspecified flaw exists in the Thread Pooling subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition.

    "The version of MySQL running on the remote host is 5.6.x prior to
    5.6.36. It is, therefore, affected by multiple vulnerabilities :
    
      - A carry propagation error exists in the OpenSSL
        component in the Broadwell-specific Montgomery
        multiplication procedure when handling input lengths
        divisible by but longer than 256 bits. This can result
        in transient authentication and key negotiation failures
        or reproducible erroneous outcomes of public-key
        operations with specially crafted input. A
        man-in-the-middle attacker can possibly exploit this
        issue to compromise ECDH key negotiations that utilize
        Brainpool P-512 curves. (CVE-2016-7055)
    
      - An authentication information disclosure vulnerability,
        known as Riddle, exists due to authentication being
        performed prior to security parameter verification. A
        man-in-the-middle (MitM) attacker can exploit this
        vulnerability to disclose sensitive authentication
        information, which the attacker can later use for
        authenticating to the server. (CVE-2017-3305)
    
      - Multiple unspecified flaws exist in the DML subcomponent
        that allow an authenticated, remote attacker to cause a
        denial of service condition. (CVE-2017-3308,
        CVE-2017-3456)
    
      - Multiple unspecified flaws exist in the Optimizer
        subcomponent that allow an authenticated, remote
        attacker to cause a denial of service condition.
        (CVE-2017-3309, CVE-2017-3452, CVE-2017-3453)
    
      - An unspecified flaw exists in the Thread Pooling
        subcomponent that allows an unauthenticated, remote
        attacker to cause a denial of service condition.
        (CVE-2017-3329)
    
      - An unspecified flaw exists in the Memcached subcomponent
        that allows an unauthenticated, remote attacker to cause
        a denial of service condition. (CVE-2017-3450)
    
      - Multiple unspecified flaws exist in the
        'Security: Privileges' subcomponent that allow an
        authenticated, remote attacker to cause a denial of
        service condition. (CVE-2017-3461, CVE-2017-3462,
        CVE-2017-3463)
    
      - An unspecified flaw exists in the DDL subcomponent that
        allows an authenticated, remote attacker to update,
        insert, or delete data contained in the database.
        (CVE-2017-3464)
    
      - An unspecified flaw exists in the Pluggable Auth
        subcomponent that allows an unauthenticated, remote
        attacker to cause a denial of service condition.
        (CVE-2017-3599)
    
      - An unspecified flaw exists in the 'Client mysqldump'
        subcomponent that allows an authenticated, remote
        attacker to execute arbitrary code. (CVE-2017-3600)
    
      - An out-of-bounds read error exists in the OpenSSL
        component when handling packets using the
        CHACHA20/POLY1305 or RC4-MD5 ciphers. An
        unauthenticated, remote attacker can exploit this, via
        specially crafted truncated packets, to cause a denial
        of service condition. (CVE-2017-3731)
    
      - A carry propagating error exists in the OpenSSL
        component in the x86_64 Montgomery squaring
        implementation that may cause the BN_mod_exp() function
        to produce incorrect results. An unauthenticated, remote
        attacker with sufficient resources can exploit this to
        obtain sensitive information regarding private keys.

    descriptionThe version of MySQL running on the remote host is 5.7.x prior to 5.7.18. It is, therefore, affected by multiple vulnerabilities : - A carry propagation error exists in the OpenSSL component in the Broadwell-specific Montgomery multiplication procedure when handling input lengths divisible by but longer than 256 bits. This can result in transient authentication and key negotiation failures or reproducible erroneous outcomes of public-key operations with specially crafted input. A man-in-the-middle attacker can possibly exploit this issue to compromise ECDH key negotiations that utilize Brainpool P-512 curves.

descriptionMySQL server is affected by a remote DoS attack, which could be exploited by a remote unauthenticated attacker to cause a loss of availability on the targeted service. The issue has been verified to affect 5.6.X branch up to 5.6.35 and 5.7.X branch up to 5.7.17\. It is strongly recommended that MySQL servers are updated to the [latest version](https://dev.mysql.com/downloads/mysql/). Upon connection from a client, the server sends a greeting message and the client continues the communication by starting the authentication process. The authentication packet sent by the client contains a wealth of information including the client capabilities, username, password, etc. The packet is received by the server, and parsed by `parse_client_handshake_packet()` function, in /sql/auth/sql_authentication.cc. In particular, the following code retrieves the password from the packet: ``` passwd= get_length_encoded_string(&end, &bytes_remaining_in_packet, &passwd_len); ``` `_get_length_encoded_string_` in turn calls `_get_56_lenc_string_` function. The password field in the packet is defined by two values: the length of the password (1 byte), followed by the actual password field content. This length is calculated by calling the `net_field_length_ll()` function. ``` my_ulonglong net_field_length_ll(uchar **packet) { uchar *pos= *packet; if (*pos < 251) { (*packet)++; return (my_ulonglong) *pos; } if (*pos == 251) { (*packet)++; return (my_ulonglong) NULL_LENGTH; } if (*pos == 252) { (*packet)+=3; return (my_ulonglong) uint2korr(pos+1); } if (*pos == 253) { (*packet)+=4; return (my_ulonglong) uint3korr(pos+1); } (*packet)+=9; /* Must be 254 when here */ return (my_ulonglong) uint8korr(pos+1); } ``` As shown in the code above, if the buffer sent to the MySQL server points to a length of \xFF, the pointer to the packet would be increased by 9 bytes. If an attacker sends an authentication packet with a password length of \xFE or \xFF with less than 9 bytes following that value, the `net_field_length_ll` function will position the pointer to the packet outside the boundaries of the variable. The _get_56_lenc_string_ function will continue the execution calculating the number of bytes remaining in the packet. The instruction `max_bytes_available -= len_len` will provoke an integer overflow where the value of max_bytes_available will become a very large unsigned integer. The next time `get_string` function is called, it will make _memchr_ read out of boundaries and exit with a segmentation fault. A [Proof of Concept](https://github.com/SECFORCE/CVE-2017-3599) code for this vulnerability has been released. #### References: [Oracle Critical Patch Update](http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618.html)
