Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • XML Nested Payloads
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. By nesting XML data and causing this data to be continuously self-referential, an attacker can cause the XML parser to consume more resources while processing, causing excessive memory consumption and CPU utilization. An attacker's goal is to leverage parser failure to his or her advantage. In most cases this type of an attack will result in a denial of service due to an application becoming unstable, freezing, or crash. However it may be possible to cause a crash resulting in arbitrary code execution, leading to a jump from the data plane to the control plane [R.230.1].
  • XML Oversized Payloads
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. By supplying oversized payloads in input vectors that will be processed by the XML parser, an attacker can cause the XML parser to consume more resources while processing, causing excessive memory consumption and CPU utilization, and potentially cause execution of arbitrary code. An attacker's goal is to leverage parser failure to his or her advantage. In many cases this type of an attack will result in a denial of service due to an application becoming unstable, freezing, or crash. However it is possible to cause a crash resulting in arbitrary code execution, leading to a jump from the data plane to the control plane [R.231.1].
  • Violating Implicit Assumptions Regarding XML Content (aka XML Denial of Service (XDoS))
    XML Denial of Service (XDoS) can be applied to any technology that utilizes XML data. This is, of course, most distributed systems technology including Java, .Net, databases, and so on. XDoS is most closely associated with web services, SOAP, and Rest, because remote service requesters can post malicious XML payloads to the service provider designed to exhaust the service provider's memory, CPU, and/or disk space. The main weakness in XDoS is that the service provider generally must inspect, parse, and validate the XML messages to determine routing, workflow, security considerations, and so on. It is exactly these inspection, parsing, and validation routines that XDoS targets. There are three primary attack vectors that XDoS can navigate Target CPU through recursion: attacker creates a recursive payload and sends to service provider Target memory through jumbo payloads: service provider uses DOM to parse XML. DOM creates in memory representation of XML document, but when document is very large (for example, north of 1 Gb) service provider host may exhaust memory trying to build memory objects. XML Ping of death: attack service provider with numerous small files that clog the system. All of the above attacks exploit the loosely coupled nature of web services, where the service provider has little to no control over the service requester and any messages the service requester sends.
  • XML Parser Attack
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. These adverse effects may include the parser crashing, consuming too much of a resource, executing too slowly, executing code supplied by an attacker, allowing usage of unintended system functionality, etc. An attacker's goal is to leverage parser failure to his or her advantage. In some cases it may be possible to jump from the data plane to the control plane via bad data being passed to an XML parser. [R.99.1]

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

  - When PHP EXIF extension is parsing EXIF information
    from an image, e.g. via exif_read_data() function, in
    PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and
    7.4.0 it is possible to supply it with data what will
    cause it to read past the allocated buffer. This may
    lead to information disclosure or
    crash.(CVE-2019-11050)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13
    and 7.4.0, PHP bcmath extension functions on some
    systems, including Windows, can be tricked into reading
    beyond the allocated space by supplying it with string
    containing characters that are identified as numeric by
    the OS but aren't ASCII numbers. This can read to
    disclosure of the content of some memory
    locations.(CVE-2019-11046)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13
    and 7.4.0, PHP DirectoryIterator class accepts
    filenames with embedded \0 byte and treats them as
    terminating at that byte. This could lead to security
    vulnerabilities, e.g. in applications checking paths
    that the code is allowed to access.(CVE-2019-11045)

  - When PHP EXIF extension is parsing EXIF information
    from an image, e.g. via exif_read_data() function, in
    PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and
    7.4.0 it is possible to supply it with data what will
    cause it to read past the allocated buffer. This may
    lead to information disclosure or
    crash.(CVE-2019-11047)

  - PHP through 7.1.11 enables potential SSRF in
    applications that accept an fsockopen or pfsockopen
    hostname argument with an expectation that the port
    number is constrained. Because a :port syntax is
    recognized, fsockopen will use the port number that is
    specified in the hostname argument, instead of the port
    number in the second argument of the
    function.(CVE-2017-7272)

  - Oniguruma before 6.9.3 allows Stack Exhaustion in
    regcomp.c because of recursion in
    regparse.c.(CVE-2019-16163)

  - Oniguruma through 6.9.3, as used in PHP 7.3.x and other
    products, has a heap-based buffer over-read in
    str_lower_case_match in regexec.c.(CVE-2019-19246)

  - An issue was discovered in Oniguruma 6.x before
    6.9.4_rc2. In the function fetch_interval_quantifier
    (formerly known as fetch_range_quantifier) in
    regparse.c, PFETCH is called without checking PEND.
    This leads to a heap-based buffer
    over-read.(CVE-2019-19204)

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.");
