AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Jenkins Maven Cascade Release Plugin 1.3.2 and earlier lacks permission checks in several HTTP endpoints, allowing attackers with Overall/Read to trigger builds and reconfigure the plugin.
Vulnerability
Overview
The Jenkins Maven Cascade Release Plugin, up to and including version 1.3.2, fails to perform necessary permission checks on multiple HTTP endpoints. This missing authorization allows any user with the Overall/Read permission to access sensitive functions that should require higher privileges [1][3].
Exploitation
An attacker who has only the Overall/Read permission can exploit this vulnerability by directly calling the unguarded endpoints. No additional authentication or special network access is needed beyond a standard Jenkins account with Overall/Read [2]. The plugin does not verify that the user has permissions such as Job/Build or Job/Configure before allowing actions.
Impact
Successful exploitation enables the attacker to start cascade builds and layout builds, as well as to reconfigure the plugin settings. This can lead to unauthorized builds consuming resources, accidental release of changes, or altered plugin behavior [1][3].
Mitigation
As of the advisory date (2020-10-08), no fixed version of the plugin was available. The vulnerability was announced as an unresolved security issue [2]. Administrators should monitor the plugin's GitHub repository [4] for future patches and consider restricting Overall/Read access or removing the plugin until a fix is released.
