Severity ?
Summary
In Apache Tika 1.19 (CVE-2018-11761), we added an entity expansion limit for XML parsing. However, Tika reuses SAXParsers and calls reset() after each parse, which, for Xerces2 parsers, as per the documentation, removes the user-specified SecurityManager and thus removes entity expansion limits after the first parse. Apache Tika versions from 0.1 to 1.19 are therefore still vulnerable to entity expansions which can lead to a denial of service attack. Users should upgrade to 1.19.1 or later.

Sin embargo, Tika reutiliza SAXParsers y llama a reset() tras cada análisis y, en el caso de los analizadores Xerces2, tal y como se indica en la documentación, elimina el SecurityManager especificado por el usuario y elimina los límites de expansión de entidades tras el primer análisis. Por lo tanto, las versiones de la 0.1 a la 1.19 de Apache Tika siguen siendo vulnerables a expansiones de entidades, lo que podría conducir a un ataque de denegación de servicio (DoS). Los usuarios deberían actualizar a la versión 1.19.1 o posteriores.\"}],\"metrics\":{\"cvssMetricV30\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":7.5,\"baseSeverity\":\"HIGH\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":3.9,\"impactScore\":3.6}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:L/Au:N/C:N/I:N/A:P\",\"baseScore\":5.0,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"LOW\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"PARTIAL\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":10.0,\"impactScore\":2.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-611\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:apache:tika:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"0.1\",\"versionEndIncluding\":\"1.19\",\"matchCriteriaId\":\"889B834A-0580-4075-8953-4EAA88DDEACF\"}]}]}],\"references\":[{\"url\":\"http://www.securityfocus.com/bid/105585\",\"source\":\"security@apache.org\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://access.redhat.com/errata/RHSA-2019:3892\",\"source\":\"security@apache.org\"},{\"url\":\"https://lists.apache.org/thread.html/88de8350cda9b184888ec294c813c5bd8a2081de8fd3666f8904bc05%40%3Cdev.tika.apache.org%3E\",\"source\":\"security@apache.org\"},{\"url\":\"https://security.netapp.com/advisory/ntap-20190903-0002/\",\"source\":\"security@apache.org\"},{\"url\":\"http://www.securityfocus.com/bid/105585\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://access.redhat.com/errata/RHSA-2019:3892\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://lists.apache.org/thread.html/88de8350cda9b184888ec294c813c5bd8a2081de8fd3666f8904bc05%40%3Cdev.tika.apache.org%3E\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"},{\"url\":\"https://security.netapp.com/advisory/ntap-20190903-0002/\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\"}]}}",
