What is CVE-2017-1000354?
CVE-2017-1000354 is a high-severity authentication bypass vulnerability in Jenkins Jenkins, published on 29 Jan 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to a login command which allowed impersonating any Jenkins user. The `login` command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance.
Weakness: CWE-287
