Summary

Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first argument (aka the "command" argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Manipulating User-Controlled Variables
    This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An attacker can override environment variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the attacker can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

"According to the versions of the ruby packages installed, the EulerOS
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 code injection if the first
    argument (aka the 'command' argument) to Shell#[] or
    Shell#test in lib/shell.rb is untrusted data. An
    attacker can exploit this to call an arbitrary Ruby
    method.(CVE-2019-16255)

  - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x
    through 2.6.4 mishandles path checking within
    File.fnmatch functions.(CVE-2019-15845)

  - WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7,
    2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a
    regular expression Denial of Service cause by
    looping/backtracking. A victim must expose a WEBrick
    server that uses DigestAuth to the Internet or a
    untrusted network.(CVE-2019-16201)

  - 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-2019-16254)

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.");
