Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Locate and Exploit Test APIs
    An attacker exploits a sample, demonstration, or test API that is insecure by default and should not be resident on production systems. Some applications include APIs that are intended to allow an administrator to test and refine their domain. These APIs should usually be disabled once a system enters a production environment. Testing APIs may expose a great deal of diagnostic information intended to aid an administrator, but which can also be used by an attacker to further refine their attack. Moreover, testing APIs may not have adequate security controls or may not have undergone rigorous testing since they were not intended for use in production environments. As such, they may have many flaws and vulnerabilities that would allow an attacker to severely disrupt a target.
  • Flooding
    An attacker consumes the resources of a target by rapidly engaging in a large number of interactions with the target. This type of attack generally exposes a weakness in rate limiting or flow control in management of interactions. Since each request consumes some of the target's resources, if a sufficiently large number of requests must be processed at the same time then the target's resources can be exhausted. The degree to which the attack is successful depends upon the volume of requests in relation to the amount of the resource the target has access to, and other mitigating circumstances such as the target's ability to shift load or acquired additional resources to deal with the depletion. The more protected the resource and the greater the quantity of it that must be consumed, the more resources the attacker may need to have at their disposal. A typical TCP/IP flooding attack is a Distributed Denial-of-Service attack where many machines simultaneously make a large number of requests to a target. Against a target with strong defenses and a large pool of resources, many tens of thousands of attacking machines may be required. When successful this attack prevents legitimate users from accessing the service and can cause the target to crash. This attack differs from resource depletion through leaks or allocations in that the latter attacks do not rely on the volume of requests made to the target but instead focus on manipulation of the target's operations. The key factor in a flooding attack is the number of requests the attacker can make in a given period of time. The greater this number, the more likely an attack is to succeed against a given target.
  • Excessive Allocation
    An attacker causes the target to allocate excessive resources to servicing the attackers' request, thereby reducing the resources available for legitimate services and degrading or denying services. Usually, this attack focuses on memory allocation, but any finite resource on the target could be the attacked, including bandwidth, processing cycles, or other resources. This attack does not attempt to force this allocation through a large number of requests (that would be Resource Depletion through Flooding) but instead uses one or a small number of requests that are carefully formatted to force the target to allocate excessive resources to service this request(s). Often this attack takes advantage of a bug in the target to cause the target to allocate resources vastly beyond what would be needed for a normal request. For example, using an Integer Attack, the attacker could cause a variable that controls allocation for a request to hold an excessively large value. Excessive allocation of resources can render a service degraded or unavailable to legitimate users and can even lead to crashing of the target.
  • XML Ping of the Death
    An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
  • XML Entity Expansion
    An attacker submits an XML document to a target application where the XML document uses nested entity expansion to produce an excessively large output XML. XML allows the definition of macro-like structures that can be used to simplify the creation of complex structures. However, this capability can be abused to create excessive demands on a processor's CPU and memory. A small number of nested expansions can result in an exponential growth in demands on memory.

"According to the versions of the binutils package installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x
    through 2.6.4 allows HTTP Response Splitting. If a
    program using WEBrick inserts untrusted input into the
    response header, an attacker can exploit it to insert a
    newline character to split a header, and inject
    malicious content to deceive clients. NOTE: this issue
    exists because of an incomplete fix for CVE-2017-17742,
    which addressed the CRLF vector, but did not address an
    isolated CR or an isolated LF.(CVE-2019-9076)

  - An issue was discovered in the Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.32. It is an attempted excessive memory
    allocation in elf_read_notes in elf.c.(CVE-2019-9074)

  - An issue was discovered in the Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.32. It is an out-of-bounds read leading to a
    SEGV in bfd_getl32 in libbfd.c, when called from
    pex64_get_runtime_function in
    pei-x86_64.c.(CVE-2019-14250)

  - An issue was discovered in GNU libiberty, as
    distributed in GNU Binutils 2.32. It is a stack
    consumption issue in d_count_templates_scopes in
    cp-demangle.c after many recursive
    calls.(CVE-2019-9071)

  - An issue was discovered in GNU libiberty, as
    distributed in GNU Binutils 2.32. It is a heap-based
    buffer over-read in d_expression_1 in cp-demangle.c
    after many recursive calls.(CVE-2019-9070)

  - The demangle_template function in cplus-dem.c in GNU
    libiberty, as distributed in GNU Binutils 2.31.1, has a
    memory leak via a crafted string, leading to a denial
    of service (memory consumption), as demonstrated by
    cxxfilt, a related issue to
    CVE-2018-12698.(CVE-2018-20657)

  - The get_count function in cplus-dem.c in GNU libiberty,
    as distributed in GNU Binutils 2.31, allows remote
    attackers to cause a denial of service (malloc called
    with the result of an integer-overflowing calculation)
    or possibly have unspecified other impact via a crafted
    string, as demonstrated by c++filt.(CVE-2018-18483)

  - The _bfd_generic_read_minisymbols function in syms.c in
    the Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.31, has a memory leak
    via a crafted ELF file, leading to a denial of service
    (memory consumption), as demonstrated by
    nm.(CVE-2018-20002)

  - apply_relocations in readelf.c in GNU Binutils 2.32
    contains an integer overflow that allows attackers to
    trigger a write access violation (in
    byte_put_little_endian function in elfcomm.c) via an
    ELF file, as demonstrated by readelf.(CVE-2019-14444)

    descriptionAccording to the versions of the binutils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - GNU Binutils 2017-04-03 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash), related to the process_mips_specific function in readelf.c, via a crafted ELF file that triggers a large memory-allocation attempt.(CVE-2017-9040) - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has an aout_link_add_symbols function in bfd/aoutx.h that is vulnerable to a heap-based buffer over-read (off-by-one) because of an incomplete check for invalid string offsets while loading symbols, leading to a GNU linker (ld) program crash.(CVE-2017-7300) - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has an aout_link_add_symbols function in bfd/aoutx.h that has an off-by-one vulnerability because it does not carefully check the string offset. The vulnerability could lead to a GNU linker (ld) program crash.(CVE-2017-7301) - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has a swap_std_reloc_out function in bfd/aoutx.h that is vulnerable to an invalid read (of size 4) because of missing checks for relocs that could not be recognised. This vulnerability causes Binutils utilities like strip to crash.(CVE-2017-7302) - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to an invalid read (of size 4) because of missing a check (in the find_link function) for null headers before attempting to match them. This vulnerability causes Binutils utilities like strip to crash.(CVE-2017-7303) - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to an invalid read (of size 8) because of missing a check (in the copy_special_section_fields function) for an invalid sh_link field before attempting to follow it. This vulnerability causes Binutils utilities like strip to crash.(CVE-2017-7304) - The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to a global buffer over-read error because of an assumption made by code that runs for objcopy and strip, that SHT_REL/SHR_RELA sections are always named starting with a .rel/.rela prefix.

    descriptionAccording to the versions of the binutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. It is a heap-based buffer over-read in d_expression_1 in cp-demangle.c after many recursive calls.(CVE-2019-9070) - An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. It is a stack consumption issue in d_count_templates_scopes in cp-demangle.c after many recursive calls.(CVE-2019-9071) - An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simple_object_elf_match in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow.(CVE-2019-14250) - An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an attempted excessive memory allocation in elf_read_notes in elf.c.(CVE-2019-9076) - An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an out-of-bounds read leading to a SEGV in bfd_getl32 in libbfd.c, when called from pex64_get_runtime_function in pei-x86_64.c.(CVE-2019-9074) - GNU gdb All versions is affected by: Buffer Overflow - Out of bound memory access. The impact is: Deny of Service, Memory Disclosure, and Possible Code Execution. The component is: The main gdb module. The attack vector is: Open an ELF for debugging. The fixed version is: Not fixed yet.(CVE-2019-1010180) - The demangle_template function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31.1, has a memory leak via a crafted string, leading to a denial of service (memory consumption), as demonstrated by cxxfilt, a related issue to CVE-2018-12698.(CVE-2018-20657) - The get_count function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31, allows remote attackers to cause a denial of service (malloc called with the result of an integer-overflowing calculation) or possibly have unspecified other impact via a crafted string, as demonstrated by c++filt.(CVE-2018-18483) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
