Jenkins Credentials Binding Plugin has Insufficiently Protected Credentials

Description

Jenkins Credentials Binding plugin allows specifying passwords and other secrets as environment variables, and will hide them from console output in builds.

However, since Jenkins will try to resolve references to other environment variables in environment variables passed to a build, this can result in values other than the one specified being provided to a build. For example, the value p4$$w0rd would result in Jenkins passing on p4$w0rd, as $$ is the escape sequence for a single $.

Credentials Binding plugin does not prevent such a transformed value (e.g. p4$w0rd) from being shown on the build log, allowing users to reconstruct the actual password value from the transformed one.

Credentials Binding plugin will now escape any $ characters in password values so they are correctly passed to the build.

This issue did apply to freestyle and other classic job types, but does not apply to Pipelines.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
