https://notcve.org/view.php?id=CVE-2021-21611
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. The highest threat from this vulnerability is to data confidentiality and integrity. • https://www.jenkins.io/security/advisory/2021-01-13/#SECURITY-2171 https://access.redhat.com/security/cve/CVE-2021-21611 https://bugzilla.redhat.com/show_bug.cgi?id=1925145 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
