Jenkins

Jenkins 2.415 and earlier, LTS 2.401.2 and earlier does not sanitize or properly encode URLs in build logs when transforming them into hyperlinks, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control build log contents.Show less

In Jenkins 2.399 and earlier, LTS 2.387.3 and earlier, POST requests are sent in order to load the list of context actions. If part of the URL includes insufficiently escaped user-provided values, a victim may be tricked into sending a POST request to an unexpected endpoint by opening a context menu.Show less

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier prints an error stack trace on agent-related pages when agent connections are broken, potentially revealing information about Jenkins configuration that is otherwise inaccessible to attackers.Show less

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier creates a temporary file in the default temporary directory with the default permissions for newly created files when uploading a file parameter through the CLI, potentially allowing attackers with access to the Jenkins controller file system to read and write the file before it is used.Show less

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier uses the Apache Commons FileUpload library without specifying limits for the number of request parts introduced in version 1.5 for CVE-2023-24998 in org.kohsuke.stapler.RequestImpl, allowing attackers to trigger a denial of service.Show less

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier uses the Apache Commons FileUpload library without specifying limits for the number of request parts introduced in version 1.5 for CVE-2023-24998 in hudson.util.MultipartFormDataParser, allowing attackers to trigger a denial of service.Show less

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier creates a temporary file in the default temporary directory with the default permissions for newly created files when uploading a plugin for installation, potentially allowing attackers with access to the Jenkins controller file system to read and write the file before it is used, potentially resulting in arbitrary code execution.Show less

Jenkins 2.270 through 2.393 (both inclusive), LTS 2.277.1 through 2.375.3 (both inclusive) does not escape the Jenkins version a plugin depends on when rendering the error message stating its incompatibility with the current version of Jenkins, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to provide plugins to the configured update sites and have this message shown by Jenkins instances.Show less

Jenkins 2.367 through 2.369 (both inclusive) does not escape tooltips of the l:helpIcon UI component used for some help icons on the Jenkins web UI, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control tooltips for this component.Show less

In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests.Show less

Jenkins 2.335 through 2.355 (both inclusive) allows attackers in some cases to bypass a protection mechanism, thereby directly accessing some view fragments containing sensitive information, bypassing any permission checks in the corresponding view.Show less

In Jenkins 2.355 and earlier, LTS 2.332.3 and earlier, an observable timing discrepancy on the login form allows distinguishing between login attempts with an invalid username, and login attempts with a valid username and wrong password, when using the Jenkins user database security realm.Show less

In Jenkins 2.340 through 2.355 (both inclusive) the tooltip of the build button in list views supports HTML without escaping the job display name, resulting in a cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.Show less

In Jenkins 2.321 through 2.355 (both inclusive) and LTS 2.332.1 through LTS 2.332.3 (both inclusive) the HTML output generated for new symbol-based SVG icons includes the 'title' attribute of 'l:ionicon' (until Jenkins 2.334) and 'alt' attribute of 'l:icon' (since Jenkins 2.335) without further escaping, resulting in a cross-site scripting (XSS) vulnerability.Show less

In Jenkins 2.320 through 2.355 (both inclusive) and LTS 2.332.1 through LTS 2.332.3 (both inclusive) the help icon does not escape the feature name that is part of its tooltip, effectively undoing the fix for SECURITY-1955, resulting in a cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.Show less

XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible.Show less
