Summary

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • 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.
  • Inducing Account Lockout
    An attacker leverages the security functionality of the system aimed at thwarting potential attacks to launch a denial of service attack against a legitimate system user. Many systems, for instance, implement a password throttling mechanism that locks an account after a certain number of incorrect log in attempts. An attacker can leverage this throttling mechanism to lock a legitimate user out of their own account. The weakness that is being leveraged by an attacker is the very security feature that has been put in place to counteract attacks.
  • 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.

    "This update for nginx fixes the following issues :
    
    nginx was updated to 1.14.2 :
    
      - Bugfix: nginx could not be built on Fedora 28 Linux.
    
      - Bugfix: in handling of client addresses when using unix
        domain listen sockets to work with datagrams on Linux.
    
      - Change: the logging level of the 'http request', 'https
        proxy request', 'unsupported protocol', 'version too
        low', 'no suitable key share', and 'no suitable
        signature algorithm' SSL errors has been lowered from
        'crit' to 'info'.
    
      - Bugfix: when using OpenSSL 1.1.0 or newer it was not
        possible to switch off 'ssl_prefer_server_ciphers' in a
        virtual server if it was switched on in the default
        server.
    
      - Bugfix: nginx could not be built with LibreSSL 2.8.0.
    
      - Bugfix: if nginx was built with OpenSSL 1.1.0 and used
        with OpenSSL 1.1.1, the TLS 1.3 protocol was always
        enabled.
    
      - Bugfix: sending a disk-buffered request body to a gRPC
        backend might fail.
    
      - Bugfix: connections with some gRPC backends might not be
        cached when using the 'keepalive' directive.
    
      - Bugfix: a segmentation fault might occur in a worker
        process if the ngx_http_mp4_module was used on 32-bit
        platforms.
    
    Changes with nginx 1.14.1 :
    
      - Security: when using HTTP/2 a client might cause
        excessive memory consumption (CVE-2018-16843) and CPU
        usage (CVE-2018-16844).
    
      - Security: processing of a specially crafted mp4 file
        with the ngx_http_mp4_module might result in worker
        process memory disclosure (CVE-2018-16845).
    
      - Bugfix: working with gRPC backends might result in
        excessive memory consumption.
    
    Changes with nginx 1.13.12 :
    
      - Bugfix: connections with gRPC backends might be closed
        unexpectedly when returning a large response.
    
    Changes with nginx 1.13.10
    
      - Feature: the 'set' parameter of the 'include' SSI
        directive now allows writing arbitrary responses to a
        variable; the 'subrequest_output_buffer_size' directive
        defines maximum response size.
    
      - Feature: now nginx uses clock_gettime(CLOCK_MONOTONIC)
        if available, to avoid timeouts being incorrectly
        triggered on system time changes.
    
      - Feature: the 'escape=none' parameter of the 'log_format'
        directive. Thanks to Johannes Baiter and Calin Don.
    
      - Feature: the $ssl_preread_alpn_protocols variable in the
        ngx_stream_ssl_preread_module.
    
      - Feature: the ngx_http_grpc_module.
    
      - Bugfix: in memory allocation error handling in the 'geo'
        directive.
    
      - Bugfix: when using variables in the
        'auth_basic_user_file' directive a null character might
        appear in logs. Thanks to Vadim Filimonov."
