In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can reach 100% upon receiving a large invalid TLS frame. En Eclipse Jetty versiones 7.2.2 hasta 9.4.38, versiones 10.0.0.alpha0 hasta 10.0.1 y versiones 11.0.0.alpha0 hasta 11.0.1, el uso de CPU puede alcanzar el 100% al recibir una gran trama TLS no válida. When using SSL/TLS with Jetty, either with HTTP/1.1, HTTP/2, or WebSocket, the server may receive an invalid large (greater than 17408) TLS frame that is incorrectly handled, causing high CPU resources utilization. The highest threat from this vulnerability is to service availability. • https://github.com/uthrasri/CVE-2021-28165 http://www.openwall.com/lists/oss-security/2021/04/20/3 https://github.com/eclipse/jetty.project/security/advisories/GHSA-26vr-8j45-3r4w https://lists.apache.org/thread.html/r002258611ed0c35b82b839d284b43db9dcdec120db8afc1c993137dc%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r03ca0b69db1e3e5f72fe484b71370d537cd711cbf334e2913332730a%40%3Cissues.spark.apache.org%3E https://lists.apache.org/thread.html/r05db8e0ef01e1280cc7543575ae0fa1c2b4d06a8b928916ef65dd2ad%40%3Creviews.spark • CWE-400: Uncontrolled Resource Consumption CWE-551: Incorrect Behavior Order: Authorization Before Parsing and Canonicalization CWE-755: Improper Handling of Exceptional Conditions •

Jenkins 2.275 and LTS 2.263.2 allows reading arbitrary files using the file browser for workspaces and archived artifacts due to a time-of-check to time-of-use (TOCTOU) race condition. Jenkins versiones 2.275 y LTS 2.263.2, permiten leer archivos arbitrarios usando el explorador de archivos para espacios de trabajo y artefactos archivados debido a una condición de carrera de tipo time-of-check a time-of-use (TOCTOU) • http://www.openwall.com/lists/oss-security/2021/01/26/2 https://www.jenkins.io/security/advisory/2021-01-26/#SECURITY-2197 https://access.redhat.com/security/cve/CVE-2021-21615 https://bugzilla.redhat.com/show_bug.cgi?id=1921322 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not implement any restrictions for the URL rendering a formatted preview of markup passed as a query parameter, resulting in a reflected cross-site scripting (XSS) vulnerability if the configured markup formatter does not prohibit unsafe elements (JavaScript) in markup. Jenkins versiones 2.274 y anteriores, LTS versiones 2.263.1 y anteriores, no implementan ninguna restricción para la URL que presenta una vista previa formateada del marcado pasado como un parámetro de consulta, resultando en una vulnerabilidad de tipo cross-site scripting (XSS) reflejada si el formateador de marcado configurado no prohíbe elementos no seguros (JavaScript) en el marcado. A flaw was found in jenkins. A cross-site scripting (XSS) vulnerability is possible due to the lack of restrictions in URL rendering in the formatted previews of markup passed as a query parameter if the configured markup formatter does not prohibit unsafe elements in the markup. The highest threat from this vulnerability is to data confidentiality and integrity. • https://www.jenkins.io/security/advisory/2021-01-13/#SECURITY-2153 https://access.redhat.com/security/cve/CVE-2021-21610 https://bugzilla.redhat.com/show_bug.cgi?id=1925151 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not escape display names and IDs of item types shown on the New Item page, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to specify display names or IDs of item types. Jenkins versiones 2.274 y anteriores, LTS 2.263.1 y anteriores, no escapan los nombres a mostrar y los ID de los tipos de elementos que se muestran en la página New Item, resultando en una vulnerabilidad de tipo cross-site scripting (XSS) almacenado explotable por unos atacantes capaces de especificar nombres a mostrar o ID de tipos de elementos. A flaw was found in jenkins. A cross-site scripting (XSS) vulnerability is possible due to display names and IDs of item types shown on the New Item page not being properly escaped.

Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not correctly match requested URLs to the list of always accessible paths, allowing attackers without Overall/Read permission to access some URLs as if they did have Overall/Read permission. Jenkins versiones 2.274 y anteriores, LTS versiones 2.263.1 y anteriores, no hacen coincidir correctamente unas URL pedidas con la lista de rutas siempre accesibles, permitiendo a atacantes sin permiso general y de lectura acceder a algunas URL como si tuvieran permiso general y de lectura. • https://www.jenkins.io/security/advisory/2021-01-13/#SECURITY-2047 https://access.redhat.com/security/cve/CVE-2021-21609 https://bugzilla.redhat.com/show_bug.cgi?id=1925141 • CWE-863: Incorrect Authorization •
