Summary

Net::SMTP in Ruby before 2.4.0 is vulnerable to SMTP command injection via CRLF sequences in a RCPT TO or MAIL FROM command, as demonstrated by CRLF sequences immediately before and after a DATA substring.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Command Delimiters
    An attack of this type exploits a programs' vulnerabilities that allows an attacker's commands to be concatenated onto a legitimate command with the intent of targeting other resources such as the file system or database. The system that uses a filter or a blacklist input validation, as opposed to whitelist validation is vulnerable to an attacker who predicts delimiters (or combinations of delimiters) not present in the filter or blacklist. As with other injection attacks, the attacker uses the command delimiter payload as an entry point to tunnel through the application and activate additional attacks through SQL queries, shell commands, network scanning, and so on.
  • Web Logs Tampering
    Web Logs Tampering attacks involve an attacker injecting, deleting or otherwise tampering with the contents of web logs typically for the purposes of masking other malicious behavior. Additionally, writing malicious data to log files may target jobs, filters, reports, and other agents that process the logs in an asynchronous attack pattern. This pattern of attack is similar to "Log Injection-Tampering-Forging" except that in this case, the attack is targeting the logs of the web server and not the application.

    attackers to inject terminal emulator escape sequences into its log
    and possibly execute arbitrary commands via a crafted user name.
    (CVE-2017-10784)
    
    Buffer underrun in OpenSSL ASN1 decode
    
    The decode method in the OpenSSL::ASN1 module in Ruby allows attackers
    to cause a denial of service (interpreter crash) via a crafted string.
    (CVE-2017-14033)
    
    No size limit in summary length of gem spec
    
    RubyGems is vulnerable to maliciously crafted gem specifications to
    cause a denial of service attack against RubyGems clients who have
    issued a `query` command. (CVE-2017-0900)
    
    Arbitrary file overwrite due to incorrect validation of specification
    name
    
    RubyGems fails to validate specification names, allowing a maliciously
    crafted gem to potentially overwrite any file on the filesystem.
    (CVE-2017-0901)
    
    DNS hijacking vulnerability
    
    RubyGems is vulnerable to a DNS hijacking vulnerability that allows a
    MITM attacker to force the RubyGems client to download and install
    gems from a server that the attacker controls. (CVE-2017-0902)
    
    Buffer underrun vulnerability in Kernel.sprintf
    
    Ruby is vulnerable to a malicious format string which contains a
    precious specifier (*) with a huge minus value. Such situation can
    lead to a buffer overrun, resulting in a heap memory corruption or an
    information disclosure from the heap. (CVE-2017-0898)
    
    Escape sequence in the 'summary' field of gemspec
    
    RubyGems is vulnerable to maliciously crafted gem specifications that
    include terminal escape characters. Printing the gem specification
    would execute terminal escape sequences. (CVE-2017-0899)
    
    Arbitrary heap exposure during a JSON.generate call
    
    Ruby can expose arbitrary memory during a JSON.generate call. The
    issues lies in using strdup in ext/json/ext/generator/generator.c,
    which will stop after encountering a '\\0' byte, returning a pointer
    to a string of length zero, which is not the length stored in
    space_len. (CVE-2017-14064)
    
    A vulnerability was found where the rubygems module was vulnerable to
    an unsafe YAML deserialization when inspecting a gem. Applications
    inspecting gem files without installing them can be tricked to execute
    arbitrary code in the context of the ruby interpreter. (CVE-2017-0903)"
