Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Relative Path Traversal An attacker exploits a weakness in input validation on the target by supplying a specially constructed path utilizing dot and slash characters for the purpose of obtaining access to arbitrary files or resources. An attacker modifies a known path on the target in order to reach material that is not available through intended channels. These attacks normally involve adding additional path separators (/ or \) and/or dots (.), or encodings thereof, in various combinations in order to reach parent directories or entirely separate trees of the target's directory structure.
- Directory Traversal An attacker with access to file system resources, either directly or via application logic, will use various file path specification or navigation mechanisms such as ".." in path strings and absolute paths to extend their range of access to inappropriate areas of the file system. The attacker attempts to either explore the file system for recon purposes or access directories and files that are intended to be restricted from their access. Exploring the file system can be achieved through constructing paths presented to directory listing programs, such as "ls" and 'dir', or through specially crafted programs that attempt to explore the file system. The attacker engaging in this type of activity is searching for information that can be used later in a more exploitive attack. Access to restricted directories or files can be achieved through modification of path references utilized by system applications.
- File System Function Injection, Content Based An attack of this type exploits the host's trust in executing remote content including binary files. The files are poisoned with a malicious payload (targeting the file systems accessible by the target software) by the attacker and may be passed through standard channels such as via email, and standard web content like PDF and multimedia files. The attacker exploits known vulnerabilities or handling routines in the target processes. Vulnerabilities of this type have been found in a wide variety of commercial applications from Microsoft Office to Adobe Acrobat and Apple Safari web browser. When the attacker knows the standard handling routines and can identify vulnerabilities and entry points they can be exploited by otherwise seemingly normal content. Once the attack is executed, the attackers' program can access relative directories such as C:\Program Files or other standard system directories to launch further attacks. In a worst case scenario, these programs are combined with other propagation logic and work as a virus.
- Using Slashes and URL Encoding Combined to Bypass Validation Logic This attack targets the encoding of the URL combined with the encoding of the slash characters. An attacker can take advantage of the multiple way of encoding an URL and abuse the interpretation of the URL. An URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.
- Manipulating Input to File System Calls An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

CVE-2018-6914: Unintentional file and directory creation with directory traversal in tempfile and tmpdir Dir.mktmpdir method introduced by tmpdir library accepts the prefix and the suffix of the directory which is created as the first parameter. The prefix can contain relative directory specifiers '../', so this method can be used to target any directory. So, if a script accepts an external input as the prefix, and the targeted directory has inappropriate permissions or the ruby process has inappropriate privileges, the attacker can create a directory or a file at any directory. CVE-2018-8777: DoS by large request in WEBrick If an attacker sends a large request which contains huge HTTP headers, WEBrick try to process it on memory, so the request causes the out-of-memory DoS attack. CVE-2018-8778: Buffer under-read in String#unpack String#unpack receives format specifiers as its parameter, and can be specified the position of parsing the data by the specifier @. If a big number is passed with @, the number is treated as the negative value, and out-of-buffer read is occurred. So, if a script accepts an external input as the argument of String#unpack, the attacker can read data on heaps. CVE-2018-8779: Unintentional socket creation by poisoned NUL byte in UNIXServer and UNIXSocket UNIXServer.open accepts the path of the socket to be created at the first parameter. If the path contains NUL (\0) bytes, this method recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of this method, the attacker can make the socket file in the unintentional path. And, UNIXSocket.open also accepts the path of the socket to be created at the first parameter without checking NUL bytes like UNIXServer.open. So, if a script accepts an external input as the argument of this method, the attacker can accepts the socket file in the unintentional path. CVE-2018-8780: Unintentional directory traversal by poisoned NUL byte in Dir Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes.

This attack appear to be exploitable via the victim must install a malicious gem. This vulnerability appears to have been fixed in 2.7.6. (CVE-2018-1000079) If a script accepts an external input and outputs it without modification as a part of HTTP responses, an attacker can use newline characters to deceive the clients that the HTTP response header is stopped at there, and can inject fake HTTP responses after the newline characters to show malicious contents to the clients.(CVE-2017-17742) The Dir.mktmpdir method introduced by tmpdir library accepts the prefix and the suffix of the directory which is created as the first parameter. The prefix can contain relative directory specifiers '../', so this method can be used to target any directory. So, if a script accepts an external input as the prefix, and the targeted directory has inappropriate permissions or the ruby process has inappropriate privileges, the attacker can create a directory or a file at any directory.(CVE-2018-6914) If an attacker sends a large request which contains huge HTTP headers, WEBrick try to process it on memory, so the request causes the out-of-memory DoS attack.(CVE-2018-8777) String#unpack receives format specifiers as its parameter, and can be specified the position of parsing the data by the specifier @. If a big number is passed with @, the number is treated as the negative value, and out-of-buffer read is occurred. So, if a script accepts an external input as the argument of String#unpack, the attacker can read data on heaps.(CVE-2018-8778) UNIXServer.open accepts the path of the socket to be created at the first parameter. If the path contains NUL (\0) bytes, this method recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of this method, the attacker can make the socket file in the unintentional path. And, UNIXSocket.open also accepts the path of the socket to be created at the first parameter without checking NUL bytes like UNIXServer.open. So, if a script accepts an external input as the argument of this method, the attacker can accepts the socket file in the unintentional path.(CVE-2018-8779) Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of these methods, the attacker can make the unintentional directory traversal.(CVE-2018-8780)" ); script_set_attribute( attribute:"see_also", value:"https://alas.aws.amazon.com/ALAS-2018-983.html" ); script_set_attribute( attribute:"solution", value: "Run 'yum update ruby20' to update your system.
