A carefully crafted or corrupt sqlite file can cause an infinite loop in Apache Tika's SQLite3Parser in versions 1.8-1.19.1 of Apache Tika. Chamilo LMS 1.11.8 contiene Cross-Site Scripting (XSS) en main/template/default/admin/gradebook_list.tpl en la herramienta de dependencias del gradebook, lo que permite que usuarios autenticados afecten a otros usuarios en condiciones específicas de permisos otorgados por los administradores. Se considera que esto tiene un "riesgo bajo" debido a la naturaleza de la característica que explota. • http://www.securityfocus.com/bid/106293 https://lists.apache.org/thread.html/7c021a4ea2037e52e74628e17e8e0e2acab1f447160edc8be0eae6d3%40%3Cdev.tika.apache.org%3E https://lists.apache.org/thread.html/r204ba2a9ea750f38d789d2bb429cc0925ad6133deea7cbc3001d96b5%40%3Csolr-user.lucene.apache.org%3E https://www.oracle.com/security-alerts/cpuapr2020.html https://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 1%CPEs: 1EXPL: 0CVE-2018-11796 – tika: Incomplete fix allows for XML entity expansion resulting in denial of service
https://notcve.org/view.php?id=CVE-2018-11796
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. En Apache Tika 1.19 (CVE-2018-11761), se ha añadido un límite de expansión de entidades para el análisis XML. • http://www.securityfocus.com/bid/105585 https://access.redhat.com/errata/RHSA-2019:3892 https://lists.apache.org/thread.html/88de8350cda9b184888ec294c813c5bd8a2081de8fd3666f8904bc05%40%3Cdev.tika.apache.org%3E https://security.netapp.com/advisory/ntap-20190903-0002 https://access.redhat.com/security/cve/CVE-2018-11796 https://bugzilla.redhat.com/show_bug.cgi?id=1639090 • CWE-611: Improper Restriction of XML External Entity Reference CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') •
