CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-31742 – Mozilla: Querying a WebAuthn token with a large number of allowCredential entries may have leaked cross-origin information
https://notcve.org/view.php?id=CVE-2022-31742
An attacker could have exploited a timing attack by sending a large number of allowCredential entries and detecting the difference between invalid key handles and cross-origin key handles. This could have led to cross-origin account linking in violation of WebAuthn goals. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. Un atacante podría haber aprovechado un ataque de sincronización enviando una gran cantidad de entradas allowCredential y detectando la diferencia entre identificadores de claves no válidas y identificadores de claves de origen cruzado. Esto podría haber llevado a la vinculación de cuentas entre orígenes en violación de los objetivos de WebAuthn. • https://bugzilla.mozilla.org/show_bug.cgi?id=1730434 https://www.mozilla.org/security/advisories/mfsa2022-20 https://www.mozilla.org/security/advisories/mfsa2022-21 https://www.mozilla.org/security/advisories/mfsa2022-22 https://access.redhat.com/security/cve/CVE-2022-31742 https://bugzilla.redhat.com/show_bug.cgi?id=2092025 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

https://notcve.org/view.php?id=CVE-2022-1802
If an attacker was able to corrupt the methods of an Array object in JavaScript via prototype pollution, they could have achieved execution of attacker-controlled JavaScript code in a privileged context. This vulnerability affects Firefox ESR < 91.9.1, Firefox < 100.0.2, Firefox for Android < 100.3.0, and Thunderbird < 91.9.1. Si un atacante pudo corromper los métodos de un objeto Array en JavaScript mediante la contaminación de prototipos, podría haber logrado la ejecución del código JavaScript controlado por el atacante en un contexto privilegiado. Esta vulnerabilidad afecta a Firefox ESR < 91.9.1, Firefox < 100.0.2, Firefox para Android < 100.3.0 y Thunderbird < 91.9.1. The Mozilla Foundation Security Advisory describes this flaw as: If an attacker was able to corrupt the methods of an Array object in JavaScript via prototype pollution, they could have achieved execution of attacker-controlled JavaScript code in a privileged context. • https://github.com/mistymntncop/CVE-2022-1802 https://bugzilla.mozilla.org/show_bug.cgi?id=1770137 https://www.mozilla.org/security/advisories/mfsa2022-19 https://access.redhat.com/security/cve/CVE-2022-1802 https://bugzilla.redhat.com/show_bug.cgi?id=2089217 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •

https://notcve.org/view.php?id=CVE-2022-1529
An attacker could have sent a message to the parent process where the contents were used to double-index into a JavaScript object, leading to prototype pollution and ultimately attacker-controlled JavaScript executing in the privileged parent process. This vulnerability affects Firefox ESR < 91.9.1, Firefox < 100.0.2, Firefox for Android < 100.3.0, and Thunderbird < 91.9.1. Un atacante podría haber enviado un mensaje al proceso principal donde el contenido se usó para realizar un doble índice en un objeto JavaScript, lo que provocó la contaminación del prototipo y, en última instancia, la ejecución de JavaScript controlada por el atacante en el proceso principal privilegiado.

https://notcve.org/view.php?id=CVE-2022-21190
This affects the package convict before 6.2.3. This is a bypass of [CVE-2022-22143](https://security.snyk.io/vuln/SNYK-JS-CONVICT-2340604). The [fix](https://github.com/mozilla/node-convict/commit/3b86be087d8f14681a9c889d45da7fe3ad9cd880) introduced, relies on the startsWith method and does not prevent the vulnerability: before splitting the path, it checks if it starts with __proto__ or this.constructor.prototype. To bypass this check it's possible to prepend the dangerous paths with any string value followed by a dot, like for example foo.__proto__ or foo.this.constructor.prototype. • https://gist.github.com/dellalibera/cebce20e51410acebff1f46afdc89808 https://github.com/mozilla/node-convict/blob/3b86be087d8f14681a9c889d45da7fe3ad9cd880/packages/convict/src/main.js%23L571 https://github.com/mozilla/node-convict/blob/master/CHANGELOG.md%23623---2022-05-07 https://github.com/mozilla/node-convict/commit/1ea0ab19c5208f66509e1c43b0d0f21c1fd29b75 https://snyk.io/vuln/SNYK-JS-CONVICT-2774757 • CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
