CVE-2020-10663 – rubygem-json: Unsafe object creation vulnerability in JSON
https://notcve.org/view.php?id=CVE-2020-10663
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. La gema JSON versiones hasta 2.2.0 para Ruby, como es usado en Ruby versiones 2.4 hasta 2.4.9, versiones 2.5 hasta 2.5.7 y versiones 2.6 hasta 2.6.5, tiene una Vulnerabilidad de Creación de Objetos No Segura. Esto es bastante similar a CVE-2013-0269, pero no se basa en un comportamiento inapropiado garbage-collection dentro de Ruby. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00004.html http://seclists.org/fulldisclosure/2020/Dec/32 https://lists.apache.org/thread.html/r37c0e1807da7ff2bdd028bbe296465a6bbb99e2320dbe661d5d8b33b%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r3b04f4e99a19613f88ae088aa18cd271231a3c79dfff8f5efa8cda61%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r5f17bfca1d6e7f4b33ae978725b2fd62a9f1b3111696eafa9add802d%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r8d2e174230f6d26e16c0 • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVE-2013-0340
https://notcve.org/view.php?id=CVE-2013-0340
expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE. expat 2.1.0 y anteriores no maneja adecuadamente entidades de expansión a menos que un desarrollador de aplicaciones use la función XML_SetEntityDeclHandler, esto permite a atacantes remotos provocar una denegación de servicio (consumo de recursos), enviar peticiones HTTP a los servidores de la intranet, o leer archivos arbitrarios a través de un documento XML manipulado, también conocido como problema XML External Entity (XXE) NOTA: se podría argumentar que debido a que expat ya ofrece la posibilidad de desactivar la expansión entidad externa, la responsabilidad de la solución de este problema se encuentra con los desarrolladores de aplicaciones, de acuerdo con este argumento, esta entrada debe ser rechazada, y cada aplicación afectada tendría su propio CVE . • http://openwall.com/lists/oss-security/2013/02/22/3 http://seclists.org/fulldisclosure/2021/Oct/61 http://seclists.org/fulldisclosure/2021/Oct/62 http://seclists.org/fulldisclosure/2021/Oct/63 http://seclists.org/fulldisclosure/2021/Sep/33 http://seclists.org/fulldisclosure/2021/Sep/34 http://seclists.org/fulldisclosure/2021/Sep/35 http://seclists.org/fulldisclosure/2021/Sep/38 http://seclists.org/fulldisclosure/2021/Sep/39 http://seclists.org/fulldisclosure/2021/Sep • CWE-611: Improper Restriction of XML External Entity Reference •
