Summary

Stack-based buffer overflow in IBM DB2 9.7 through FP9a, 9.8 through FP5, 10.1 through FP4, and 10.5 before FP4 on Linux, UNIX, and Windows allows remote authenticated users to execute arbitrary code via a crafted ALTER MODULE statement.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionAccording to its version, the installation of IBM DB2 10.1 running on the remote host is prior to Fix Pack 5. It is, therefore, affected by multiple vulnerabilities : - An unspecified flaw exists in the monitoring or audit facility due to passwords being stored when handling specially crafted commands. A remote, authenticated attacker can exploit this to access sensitive information. (CVE-2014-0919) - A stack-based buffer overflow condition exists due to improper validation of user-supplied input when handling crafted ALTER MODULE statements. A remote, authenticated attacker can exploit this to cause a denial of service or execute arbitrary code. (CVE-2014-3094) - A flaw exists when handling a crafted UNION clause in a subquery of a SELECT statement. A remote, authenticated attacker can exploit this to cause a denial of service. (CVE-2014-3095) - A denial of service vulnerability exists when immediate AUTO_REVAL is enabled. A remote, authenticated attacker can exploit this, via a crafted ALTER TABLE statement, to crash the server. (CVE-2014-6159) - A denial of service vulnerability exists when handling an identity column within a crafted ALTER TABLE statement. A remote, authenticated attacker can exploit this vulnerability to crash the server. (CVE-2014-6209) - A denial of service vulnerability exists when handling multiple ALTER TABLE statements specifying the same column. A remote, authenticated attacker can exploit this vulnerability to crash the server. (CVE-2014-6210) - A flaw exists that is triggered when handling specially crafted XML queries. A remote, authenticated attacker can exploit this to cause a consumption of resources, resulting in a denial of service. (CVE-2014-8901) - An unspecified error exists during the handling of SELECT statements with XML/XSLT functions that allows a remote attacker to gain access to arbitrary files. (CVE-2014-8910) - A flaw exists in the IBM Global Security Kit (GSKit) when handling RSA temporary keys in a non-export RSA key exchange ciphersuite. A man-in-the-middle attacker can exploit this to downgrade the session security to use weaker EXPORT_RSA ciphers, thus allowing the attacker to more easily monitor or tamper with the encrypted stream. (CVE-2015-0138) - A flaw exists in the LUW component when handling SQL statements with unspecified Scaler functions. A remote, authenticated attacker can exploit this to cause a denial of service. (CVE-2015-0157) - An unspecified flaw in the General Parallel File System (GPFS) allows a local attacker to gain root privileges. (CVE-2015-0197) - A flaw exists in the General Parallel File System (GPFS), related to certain cipherList configurations, that allows a remote attacker, using specially crafted data, to bypass authentication and execute arbitrary programs with root privileges. (CVE-2015-0198) - A denial of service vulnerability exists in the General Parallel File System (GPFS) that allows a local attacker to corrupt kernel memory by sending crafted ioctl character device calls to the mmfslinux kernel module. (CVE-2015-0199) - An information disclosure vulnerability exists in the automated maintenance feature. An attacker with elevated privileges can exploit this issue by manipulating a stored procedure, resulting in the disclosure of arbitrary files owned by the DB2 fenced ID on UNIX/Linux or the administrator on Windows. (CVE-2015-1883) - A flaw exists in the Data Movement feature when handling specially crafted queries. An authenticated, remote attacker can exploit this to delete database rows from a table without having the appropriate privileges. (CVE-2015-1922) - An unspecified flaw exists when handling SQL statements with LUW Scaler functions. An authenticated, remote attacker can exploit this to run arbitrary code, under the privileges of the DB2 instance owner, or to cause a denial of service. (CVE-2015-1935) - A security feature bypass vulnerability exists, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase. A man-in-the-middle attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic. (CVE-2015-2808) - A flaw exists when handling

      script_set_attribute(attribute:"description", value:
    "According to its version, the installation of IBM DB2 10.1 running on
    the remote host is prior to Fix Pack 5. It is, therefore, affected by
    multiple vulnerabilities :
    
      - An unspecified flaw exists in the monitoring or audit
        facility due to passwords being stored when handling
        specially crafted commands. A remote, authenticated
        attacker can exploit this to access sensitive
        information. (CVE-2014-0919)
    
      - A stack-based buffer overflow condition exists due to
        improper validation of user-supplied input when handling
        crafted ALTER MODULE statements. A remote, authenticated
        attacker can exploit this to cause a denial of service
        or execute arbitrary code. (CVE-2014-3094)
    
      - A flaw exists when handling a crafted UNION clause in a
        subquery of a SELECT statement. A remote, authenticated
        attacker can exploit this to cause a denial of service.
        (CVE-2014-3095)
    
      - A denial of service vulnerability exists when immediate
        AUTO_REVAL is enabled. A remote, authenticated attacker
        can exploit this, via a crafted ALTER TABLE statement,
        to crash the server. (CVE-2014-6159)
    
      - A denial of service vulnerability exists when handling
        an identity column within a crafted ALTER TABLE
        statement. A remote, authenticated attacker can exploit
        this vulnerability to crash the server. (CVE-2014-6209)
    
      - A denial of service vulnerability exists when handling
        multiple ALTER TABLE statements specifying the same
        column. A remote, authenticated attacker can exploit
        this vulnerability to crash the server. (CVE-2014-6210)
    
      - A flaw exists that is triggered when handling specially
        crafted XML queries. A remote, authenticated attacker
        can exploit this to cause a consumption of resources,
        resulting in a denial of service. (CVE-2014-8901)
    
      - An unspecified error exists during the handling of
        SELECT statements with XML/XSLT functions that allows a
        remote attacker to gain access to arbitrary files.
        (CVE-2014-8910)
    
      - A flaw exists in the IBM Global Security Kit (GSKit)
        when handling RSA temporary keys in a non-export RSA key
        exchange ciphersuite. A man-in-the-middle attacker can
        exploit this to downgrade the session security to use
        weaker EXPORT_RSA ciphers, thus allowing the attacker to
        more easily monitor or tamper with the encrypted stream.
        (CVE-2015-0138)
    
      - A flaw exists in the LUW component when handling SQL
        statements with unspecified Scaler functions. A remote,
        authenticated attacker can exploit this to cause a
        denial of service. (CVE-2015-0157)
    
      - An unspecified flaw in the General Parallel File System
        (GPFS) allows a local attacker to gain root privileges.
        (CVE-2015-0197)
    
      - A flaw exists in the General Parallel File System
        (GPFS), related to certain cipherList configurations,
        that allows a remote attacker, using specially crafted
        data, to bypass authentication and execute arbitrary
        programs with root privileges. (CVE-2015-0198)
    
      - A denial of service vulnerability exists in the General
        Parallel File System (GPFS) that allows a local attacker
        to corrupt kernel memory by sending crafted ioctl
        character device calls to the mmfslinux kernel module.
        (CVE-2015-0199)
    
      - An information disclosure vulnerability exists in the
        automated maintenance feature. An attacker with elevated
        privileges can exploit this issue by manipulating a
        stored procedure, resulting in the disclosure of
        arbitrary files owned by the DB2 fenced ID on UNIX/Linux
        or the administrator on Windows. (CVE-2015-1883)
    
      - A flaw exists in the Data Movement feature when handling
        specially crafted queries. An authenticated, remote
        attacker can exploit this to delete database rows from a
        table without having the appropriate privileges.
        (CVE-2015-1922)
    
      - An unspecified flaw exists when handling SQL statements
        with LUW Scaler functions. An authenticated, remote
        attacker can exploit this to run arbitrary code, under
        the privileges of the DB2 instance owner, or to cause a
        denial of service. (CVE-2015-1935)
    
      - A security feature bypass vulnerability exists, known as
        Bar Mitzvah, due to improper combination of state data
        with key data by the RC4 cipher algorithm during the
        initialization phase. A man-in-the-middle attacker can
        exploit this, via a brute-force attack using LSB values,
        to decrypt the traffic. (CVE-2015-2808)
    
      - A flaw exists when handling 'SUM' or 'GROUP BY' queries
        with a 'SUBSELECT' that contains 'unnest'. An
        authenticated, remote attacker can exploit this to cause
        a denial of service condition.
    
      - A use-after-free error exists in the CLI application due
        to improper validation of user-supplied input when
        handling client disconnects. An unauthenticated, remote
        attacker can exploit this to corrupt memory, resulting
        in a denial of service condition or the execution of
        arbitrary code.
    
      - A denial of service vulnerability exists due to an
        unspecified flaw in the sqldRemoveCachedTableEntry()
        function. An authenticated, remote attacker can exploit
        this to crash a DB2 instance.
    
      - An out-of-bounds write error exists due to improper
        validation of user-supplied input when handling the
        Partial Aggregation Operators (PED, PEA). A remote,
        authenticated attacker can exploit this to corrupt
        memory, resulting in a denial of service condition.
    
      - An integrity flaw exists due to insecure file
        permissions for the STMM log file. A local attacker can
        exploit this to manipulate the logs.
    
      - A denial of service vulnerability exists in the
        sqlex_find_group() function when returning a cumulative
        group name greater than 64K. An authenticated, remote
        attacker can exploit this to crash the server.
    
      - A flaw exists in the sqlsBinSortPopulateRecPointers()
        function due to improper validation of user-supplied
        input when performing resettable sorts. A remote,
        authenticated attacker can exploit this to corrupt
        memory, resulting in a denial of service.
    
      - A flaw exists that is triggered when handling 'INSERT
        INTO' statements. An authenticated, remote attacker can
        exploit this to crash DB2 when the target is a generated
        table created by a values clause containing multiple
        rows.
    
      - A flaw exists when invoking runstats against a user
        temporary table when the index clause explicitly
        specifies index names but omits the index schema name.
        An authenticated, remote attacker can exploit this to
        cause a denial of service.
    
      - A flaw exists in the DRDA communication protocol due to
        improper parsing of split DRDA messages under certain
        circumstances. An authenticated, remote attacker can
        exploit this to cause a large memory overwrite,
        resulting in a denial of service condition or the
        execution of arbitrary code.
    
      - An information disclosure vulnerability exists due to
        improper block cipher padding by TLSv1 when using Cipher
        Block Chaining (CBC) mode. A remote attacker, via an
        'Oracle Padding' side channel attack, can exploit this
        vulnerability to gain access to sensitive information.
        Note that this is a variation of the POODLE attack.
