Certain input passed into the If-Modified-Since or Last-Modified headers will cause an 'illegal access' exception to be raised. Instead of sending a HTTP 500 error back to the sender, hapi node module before 11.1.3 will continue to hold the socket open until timed out (default node timeout is 2 minutes).

Certain input strings when passed to new Date() or Date.parse() in ecstatic node module before 1.4.0 will cause v8 to raise an exception. This leads to a crash and denial of service in ecstatic when this input is passed into the server via the If-Modified-Since header.

ansi2html is vulnerable to regular expression denial of service (ReDoS) when certain types of user input is passed in.

The merge.recursive function in the merge package <1.2.1 can be tricked into adding or modifying properties of the Object prototype. These properties will be present on all objects allowing for a denial of service attack.

The qs module before 1.0.0 does not have an option or default for specifying object depth and when parsing a string representing a deeply nested object will block the event loop for long periods of time. An attacker could leverage this to cause a temporary denial-of-service condition, for example, in a web application, other requests would not be processed while this blocking is occurring.

hapi is a web and services application framework. When hapi >= 15.0.0 <= 16.1.0 encounters a malformed `accept-encoding` header an uncaught exception is thrown. This may cause hapi to crash or to hang the client connection until the timeout period is reached.

charset 1.0.0 and below are vulnerable to regular expression denial of service. Input of around 50k characters is required for a slow down of around 2 seconds. Unless node was compiled using the -DHTTP_MAX_HEADER_SIZE= option the default header max length is 80kb, so the impact of the ReDoS is relatively low.

The forwarded module is used by the Express.js framework to handle the X-Forwarded-For header. It is vulnerable to a regular expression denial of service when it's passed specially crafted input to parse. This causes the event loop to be blocked causing a denial of service condition.

Decamelize is used to convert a dash/dot/underscore/space separated string to camelCase. Decamelize 1.1.0 through 1.1.1 uses regular expressions to evaluate a string and takes unescaped separator values, which can be used to create a denial of service attack.

Denial of Service attack in airMAX < 8.3.2 , airMAX < 6.0.7 and EdgeMAX < 1.9.7 allow attackers to use the Discovery Protocol in amplification attacks.

The parsejson module is vulnerable to regular expression denial of service when untrusted user input is passed into it to be parsed.

sequelize is an Object-relational mapping, or a middleman to convert things from Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server into usable data for NodeJS In Postgres, SQLite, and Microsoft SQL Server there is an issue where arrays are treated as strings and improperly escaped. This causes potential SQL injection in sequelize 3.19.3 and earlier, where a malicious user could put `["test", "'); DELETE TestTable WHERE Id = 1 --')"]` inside of ``` database.query('SELECT * FROM TestTable WHERE Name IN (:names)', { replacements: { names: directCopyOfUserInput } }); ``` and cause the SQL statement to become `SELECT Id FROM Table WHERE Name IN ('test', '\'); DELETE TestTable WHERE Id = 1 --')`. In Postgres, MSSQL, and SQLite, the backslash has no special meaning. This causes the the statement to delete whichever Id has a value of 1 in the TestTable table.

Fastify node module before 0.38.0 is vulnerable to a denial-of-service attack by sending a request with "Content-Type: application/json" and a very large payload.

sshpk is vulnerable to ReDoS when parsing crafted invalid public keys.

A REST API endpoint that is used for development in i18n-node-angular before 1.4.0 was not disabled in production environments a malicious user could fill up the server causing a Denial of Service or content injection.

uws is a WebSocket server library. By sending a 256mb websocket message to a uws server instance with permessage-deflate enabled, there is a possibility used compression will shrink said 256mb down to less than 16mb of websocket payload which passes the length check of 16mb payload. This data will then inflate up to 256mb and crash the node process by exceeding V8's maximum string size. This affects uws >=0.10.0 <=0.10.8.

https-proxy-agent before 2.1.1 passes auth option to the Buffer constructor without proper sanitization, resulting in DoS and uninitialized memory leak in setups where an attacker could submit typed input to the 'auth' parameter (e.g. JSON).

Nes is a websocket extension library for hapi. Hapi is a webserver framework. Versions below and including 6.4.0 have a denial of service vulnerability via an invalid Cookie header. This is only present when websocket authentication is set to `cookie`. Submitting an invalid cookie on the websocket upgrade request will cause the node process to error out.

The HTTP client module superagent is vulnerable to ZIP bomb attacks. In a ZIP bomb attack, the HTTP server replies with a compressed response that becomes several magnitudes larger once uncompressed. If a client does not take special care when processing such responses, it may result in excessive CPU and/or memory consumption. An attacker might exploit such a weakness for a DoS attack. To exploit this the attacker must control the location (URL) that superagent makes a request to.

uri-js is a module that tries to fully implement RFC 3986. One of these features is validating whether or not a supplied URL is valid or not. To do this, uri-js uses a regular expression, This regular expression is vulnerable to redos. This causes the program to hang and the CPU to idle at 100% usage while uri-js is trying to validate if the supplied URL is valid or not. To check if you're vulnerable, look for a call to `require("uri-js").parse()` where a user is able to send their own input. This affects uri-js 2.1.1 and earlier.

A local file inclusion flaw was found in the way the phpLDAPadmin before 0.9.8 processed certain values of the "Accept-Language" HTTP header. A remote attacker could use this flaw to cause a denial of service via specially-crafted request.

The Store Service in Microsoft Exchange 2000 allows remote attackers to cause a denial of service (CPU consumption) via a mail message with a malformed RFC message attribute, aka "Malformed Mail Attribute can Cause Exchange 2000 to Exhaust CPU Resources."

A firewall bypass vulnerability in the proxy ARP service of Juniper Networks Junos OS allows an attacker to cause a high CPU condition leading to a Denial of Service (DoS). This issue affects only IPv4. Affected releases are Juniper Networks Junos OS: 12.1X46 versions above and including 12.1X46-D25 prior to 12.1X46-D71, 12.1X46-D73 on SRX Series; 12.3X48 versions prior to 12.3X48-D50 on SRX Series; 15.1X49 versions prior to 15.1X49-D75 on SRX Series.

The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.14 and 8.5.0 to 8.5.37 accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servlet API's blocking I/O, clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS.
