Gentoo Linux Security Advisory 202405-29 - Multiple vulnerabilities have been discovered in Node.js. Versions greater than or equal to 16.20.2 are affected.

### Impact XML External entity injections could be possible, when running the provided XML Validator on arbitrary input. #### POC ```js const { Spec: { Version }, Validation: { XmlValidator } } = require('@cyclonedx/cyclonedx-library'); const version = Version.v1dot5; const validator = new XmlValidator(version); const input = `<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE poc [ <!ENTITY xxe SYSTEM "file:///etc/passwd"> ]> <bom xmlns="http://cyclonedx.org/schema/bom/1.5"> <components> <component type="library"> <name>testing</name> <version>1.337</version> <licenses> <license> <id>&xxe;</id><!-- << XML external entity (XXE) injection --> </license> </licenses> </component> </components> </bom>`; // validating this forged(^) input might lead to unintended behaviour // for the fact that the XML external entity would be taken into account. validator.validate(input).then(ve => { console.error('validation error', v...

### Summary If PDF.js is used to load a malicious PDF, and PDF.js is configured with `isEvalSupported` set to `true` (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain. ### Patches [This patch](https://github.com/wojtekmaj/react-pdf/commit/671e6eaa2e373e404040c13cc6b668fe39839cad) forces `isEvalSupported` to `false`, removing the attack vector. ### Workarounds Set `options.isEvalSupported` to `false`, where `options` is `Document` component prop. ### References - [GHSA-wgrm-67xf-hhpq](https://github.com/mozilla/pdf.js/security/advisories/GHSA-wgrm-67xf-hhpq) - https://github.com/mozilla/pdf.js/pull/18015 - https://github.com/mozilla/pdf.js/commit/85e64b5c16c9aaef738f421733c12911a441cec6 - https://bugzilla.mozilla.org/show_bug.cgi?id=1893645

### Impact If pdf.js is used to load a malicious PDF, and PDF.js is configured with `isEvalSupported` set to `true` (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain. ### Patches The patch removes the use of `eval`: https://github.com/mozilla/pdf.js/pull/18015 ### Workarounds Set the option `isEvalSupported` to `false`. ### References https://bugzilla.mozilla.org/show_bug.cgi?id=1893645

Red Hat Security Advisory 2024-2651-03 - An update for the nodejs:16 module is now available for Red Hat Enterprise Linux 8.8 Extended Update Support. Issues addressed include a denial of service vulnerability.

### Summary Default configuration does not check authorization of the signer, it only checks the validity of the signature per section 3.2.2 of https://www.w3.org/TR/2008/REC-xmldsig-core-20080610/#sec-CoreValidation. As such, without additional validation steps, the default configuration allows a malicious actor to re-sign an XML document, place the certificate in a `<KeyInfo />` element, and pass `xml-crypto` default validation checks. ### Details Affected `xml-crypto` versions between versions `>= 4.0.0` and `< 6.0.0`. `xml-crypto` trusts by default any certificate provided via digitally signed XML document's `<KeyInfo />`. `xml-crypto` prefers to use any certificate provided via digitally signed XML document's `<KeyInfo />` even if library was configured to use specific certificate (`publicCert`) for signature verification purposes. Attacker can spoof signature verification by modifying XML document and replacing existing signature with signature generated with malicious pri...

### Summary Installation of a maliciously crafted plugin allows for remote code execution by an authenticated attacker. ### Details Uptime Kuma allows authenticated users to install plugins from an official list of plugins. This feature is currently disabled in the web interface, but the corresponding API endpoints are still available after login. After downloading a plugin, it's installed by calling `npm install` in the installation directory of the plugin: https://github.com/louislam/uptime-kuma/blob/8c60e902e1c76ecbbd1b0423b07ce615341cb850/server/plugins-manager.js#L210-L216 Because the plugin is not validated against the official list of plugins or installed with `npm install --ignore-scripts`, a maliciously crafted plugin taking advantage of [npm scripts](https://docs.npmjs.com/cli/v9/using-npm/scripts) can gain remote code execution. ### PoC In the PoC below, the plugin at https://github.com/n-thumann/npm-install-script-poc will be installed. It only consists of an empty `inde...

The ejs (aka Embedded JavaScript templates) package before 3.1.10 for Node.js lacks certain pollution protection.

An ongoing social engineering campaign is targeting software developers with bogus npm packages under the guise of a job interview to trick them into downloading a Python backdoor. Cybersecurity firm Securonix is tracking the activity under the name DEV#POPPER, linking it to North Korean threat actors. "During these fraudulent interviews, the developers are often asked
