Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier does not perform a permission check in a connection test HTTP endpoint. This allows attackers with Overall/Read permission to connect to an attacker-specified hostname and port using attacker-specified username and password. Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. Build Failure Analyzer Plugin 2.4.2 requires POST requests and Overall/Administer permission for the affected HTTP endpoint.

### Impact As a part of this vulnerability, user was able to se code using `__proto__` as a tag or attribute name. ```js const { XMLParser, XMLBuilder, XMLValidator} = require("fast-xml-parser"); let XMLdata = "<__proto__><polluted>hacked</polluted></__proto__>" const parser = new XMLParser(); let jObj = parser.parse(XMLdata); console.log(jObj.polluted) // should return hacked ``` ### Patches The problem has been patched in v4.1.2 ### Workarounds User can check for "__proto__" in the XML string before parsing it to the parser. ### References https://gist.github.com/Sudistark/a5a45bd0804d522a1392cb5023aa7ef7

Jenkins HashiCorp Vault Plugin 336.v182c0fbaaeb7 and earlier implements functionality that allows agent processes to read arbitrary files on the Jenkins controller file system.

Jenkins GitLab Authentication Plugin 1.13 and earlier records the HTTP Referer header as part of the URL query parameters when the authentication process starts, allowing attackers with access to Jenkins to craft a URL that will redirect users to an attacker-specified URL after logging in.

Jenkins Convertigo Mobile Platform Plugin 1.1 and earlier uses static fields to store job configuration information, allowing attackers with Item/Configure permission to capture passwords of the jobs that will be configured.

Jenkins Chef Sinatra Plugin 1.20 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

A cross-site request forgery (CSRF) vulnerability in Jenkins SWAMP Plugin 1.2.6 and earlier allows attackers to connect to an attacker-specified web server using attacker-specified credentials.

Jenkins Doktor Plugin 0.4.1 and earlier implements functionality that allows agent processes to render files on the controller as Markdown or Asciidoc, and error messages allow attackers able to control agent processes to determine whether a file with a given name exists.

Jenkins Team Views Plugin 0.9.0 and earlier does not escape team names, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Read permission.

Jenkins Promoted Builds (Simple) Plugin 1.9 and earlier does not escape the name of custom promotion levels, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission.
