CVSS: 9.8EPSS: 0%CPEs: 7EXPL: 1CVE-2022-39353 – xmldom allows multiple root nodes in a DOM
https://notcve.org/view.php?id=CVE-2022-39353
xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) `DOMParser` and `XMLSerializer` module. xmldom parses XML that is not well-formed because it contains multiple top level elements, and adds all root nodes to the `childNodes` collection of the `Document`, without reporting any error or throwing. This breaks the assumption that there is only a single root node in the tree, which led to issuance of CVE-2022-39299 as it is a potential issue for dependents. Update to @xmldom/xmldom@~0.7.7, @xmldom/xmldom@~0.8.4 (dist-tag latest) or @xmldom/xmldom@>=0.9.0-beta.4 (dist-tag next). As a workaround, please one of the following approaches depending on your use case: instead of searching for elements in the whole DOM, only search in the `documentElement`or reject a document with a document that has more then 1 `childNode`. xmldom es un módulo `DOMParser` y `XMLSerializer` basado en el estándar W3C de JavaScript puro (XML DOM Level 2 Core). xmldom analiza XML que no está bien formado porque contiene múltiples elementos de nivel superior y agrega todos los nodos raíz a la colección `childNodes` del `Documento`, sin informar ningún error ni arrojar. Esto rompe la suposición de que solo hay un nodo raíz en el árbol, lo que llevó a la emisión de CVE-2022-39299, ya que es un problema potencial para los dependientes. • https://github.com/jindw/xmldom/issues/150 https://github.com/xmldom/xmldom/security/advisories/GHSA-crh6-fp67-6883 https://lists.debian.org/debian-lts-announce/2023/01/msg00000.html • CWE-20: Improper Input Validation CWE-1288: Improper Validation of Consistency within Input •

A prototype pollution vulnerability exists in the function copy in dom.js in the xmldom (published as @xmldom/xmldom) package before 0.8.3 for Node.js via the p variable. NOTE: the vendor states "we are in the process of marking this report as invalid"; however, some third parties takes the position that "A prototype injection/Prototype pollution is not just when global objects are polluted with recursive merge or deep cloning but also when a target object is polluted." Se presenta una vulnerabilidad de contaminación de prototipos en la función copy en el archivo dom.js en el paquete xmldom (publicado como @xmldom/xmldom) versiones anteriores a 0.8.3 para Node.js por medio de la variable p. NOTA: el proveedor afirma que "estamos en proceso de marcar este informe como no válido" • http://users.encs.concordia.ca/~mmannan/publications/JS-vulnerability-aisaccs2022.pdf https://dl.acm.org/doi/abs/10.1145/3488932.3497769 https://dl.acm.org/doi/pdf/10.1145/3488932.3497769 https://github.com/xmldom/xmldom/blob/bc36efddf9948aba15618f85dc1addfc2ac9d7b2/lib/dom.js#L1 https://github.com/xmldom/xmldom/blob/bc36efddf9948aba15618f85dc1addfc2ac9d7b2/lib/dom.js#L3 https://github.com/xmldom/xmldom/issues/436 https://github.com/xmldom/xmldom/issues/436#issuecomment-1319412826 https://github. • CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •

https://notcve.org/view.php?id=CVE-2021-32796
xmldom is an open source pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. xmldom versions 0.6.0 and older do not correctly escape special characters when serializing elements removed from their ancestor. This may lead to unexpected syntactic changes during XML processing in some downstream applications. This issue has been resolved in version 0.7.0. As a workaround downstream applications can validate the input and reject the maliciously crafted documents. xmldom es un módulo DOMParser y XMLSerializer de código abierto basado en el estándar W3C (XML DOM Level 2 Core).

xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. xmldom versions 0.4.0 and older do not correctly preserve system identifiers, FPIs or namespaces when repeatedly parsing and serializing maliciously crafted documents. This may lead to unexpected syntactic changes during XML processing in some downstream applications. This is fixed in version 0.5.0.
