Common Weakness Enumeration (CWE)

CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

Common Attack Pattern Enumeration and Classification (CAPEC)

Accessing/Intercepting/Modifying HTTP Cookies
This attack relies on the use of HTTP Cookies to store credentials, state information and other critical data on client systems. The first form of this attack involves accessing HTTP Cookies to mine for potentially sensitive data contained therein. The second form of this attack involves intercepting this data as it is transmitted from client to server. This intercepted information is then used by the attacker to impersonate the remote user/session. The third form is when the cookie's content is modified by the attacker before it is sent back to the server. Here the attacker seeks to convince the target server to operate on this falsified information.
HTTP Response Splitting
This attack uses a maliciously-crafted HTTP request in order to cause a vulnerable web server to respond with an HTTP response stream that will be interpreted by the client as two separate responses instead of one. This is possible when user-controlled input is used unvalidated as part of the response headers. The target software, the client, will interpret the injected header as being a response to a second request, thereby causing the maliciously-crafted contents be displayed and possibly cached. To achieve HTTP Response Splitting on a vulnerable web server, the attacker:
Simple Script Injection
An attacker embeds malicious scripts in content that will be served to web browsers. The goal of the attack is for the target software, the client-side browser, to execute the script with the users' privilege level. An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute code and scripts. Web browsers, for example, have some simple security controls in place, but if a remote attacker is allowed to execute scripts (through injecting them in to user-generated content like bulletin boards) then these controls may be bypassed. Further, these attacks are very difficult for an end user to detect.
AJAX Fingerprinting
This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. In many XSS attacks the attacker must get a "hole in one" and successfully exploit the vulnerability on the victim side the first time, once the client is redirected the attacker has many chances to engage in follow on probes, but there is only one first chance. In a widely used web application this is not a major problem because 1 in a 1,000 is good enough in a widely used application. A common first step for an attacker is to footprint the environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on.

description	Multiple vulnerabilities were found in the interpreter for the Ruby language. The Common Vulnerabilities and Exposures project identifies the following issues : CVE-2017-17742 Aaron Patterson reported that WEBrick bundled with Ruby was vulnerable to an HTTP response splitting vulnerability. It was possible for an attacker to inject fake HTTP responses if a script accepted an external input and output it without modifications. CVE-2018-6914 ooooooo_q discovered a directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library. It made it possible for attackers to create arbitrary directories or files via a .. (dot dot) in the prefix argument. CVE-2018-8777 Eric Wong reported an out-of-memory DoS vulnerability related to a large request in WEBrick bundled with Ruby. CVE-2018-8778 aerodudrizzt found a buffer under-read vulnerability in the Ruby String#unpack method. If a big number was passed with the specifier @, the number was treated as a negative value, and an out-of-buffer read occurred. Attackers could read data on heaps if an script accepts an external input as the argument of String#unpack. CVE-2018-8779 ooooooo_q reported that the UNIXServer.open and UNIXSocket.open methods of the socket library bundled with Ruby did not check for NUL bytes in the path argument. The lack of check made the methods vulnerable to unintentional socket creation and unintentional socket access. CVE-2018-8780 ooooooo_q discovered an unintentional directory traversal in some methods in Dir, by the lack of checking for NUL bytes in their parameter. CVE-2018-1000075 A negative size vulnerability in ruby gem package tar header that could cause an infinite loop. CVE-2018-1000076 Ruby gems package improperly verifies cryptographic signatures. A mis-signed gem could be installed if the tarball contains multiple gem signatures. CVE-2018-1000077 An improper input validation vulnerability in ruby gems specification homepage attribute could allow malicious gem to set an invalid homepage URL. CVE-2018-1000078 Cross Site Scripting (XSS) vulnerability in gem server display of homepage attribute For Debian 7

description	Multiple vulnerabilities were found in the interpreter for the Ruby language. The Common Vulnerabilities and Exposures project identifies the following issues : CVE-2017-17742 Aaron Patterson reported that WEBrick bundled with Ruby was vulnerable to an HTTP response splitting vulnerability. It was possible for an attacker to inject fake HTTP responses if a script accepted an external input and output it without modifications. CVE-2018-6914 ooooooo_q discovered a directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library. It made it possible for attackers to create arbitrary directories or files via a .. (dot dot) in the prefix argument. CVE-2018-8777 Eric Wong reported an out-of-memory DoS vulnerability related to a large request in WEBrick bundled with Ruby. CVE-2018-8778 aerodudrizzt found a buffer under-read vulnerability in the Ruby String#unpack method. If a big number was passed with the specifier @, the number was treated as a negative value, and an out-of-buffer read occurred. Attackers could read data on heaps if an script accepts an external input as the argument of String#unpack. CVE-2018-8779 ooooooo_q reported that the UNIXServer.open and UNIXSocket.open methods of the socket library bundled with Ruby did not check for NUL bytes in the path argument. The lack of check made the methods vulnerable to unintentional socket creation and unintentional socket access. CVE-2018-8780 ooooooo_q discovered an unintentional directory traversal in some methods in Dir, by the lack of checking for NUL bytes in their parameter. For Debian 7
