Description

Incorrect permission check in XebiaLabs XL Deploy Plugin allows capturing credentials

An incorrect permission check in Jenkins XebiaLabs XL Deploy Plugin 10.0.1 and earlier allows attackers with Generic Create permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing Username/password credentials stored in Jenkins.

The permission check was partially fixed in XebiaLabs XL Deploy Plugin 7.5.9: A permission check was added, but for the wrong permission, still allowing some non-admin users to access the form validation method.

How this vulnerability can be exploited

The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.
