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') •
