2.462.3- Upgrade org.jenkins-ci.main:jenkins-core to this version or later
Description
Jenkins
Jenkins provides the secretTextarea form field for multi-line secrets.
Jenkins 2.478 and earlier, LTS 2.462.2 and earlier does not redact multi-line secret values in error messages generated for form submissions involving the secretTextarea form field.
This can result in exposure of multi-line secrets through those error messages, e.g., in the system log.
Jenkins 2.479, LTS 2.462.3 redacts multi-line secret values in error messages generated for form submissions involving the secretTextarea form field.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.jenkins-ci.main:jenkins-core | < 2.462.3 |
2.462.3 |
| org.jenkins-ci.main:jenkins-core | >= 2.466, < 2.479 |
2.479 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-209: Generation of Error Message Containing Sensitive Information
The product generates an error message that includes sensitive information about its environment, users, or associated data.
How to prevent it
- Implementation: Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success. If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files. Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
- Implementation: Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
- Implementation: Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
- Implementation, Build and Compilation: Debugging information should not make its way into a production release.
- Implementation, Build and Compilation: Debugging information should not make its way into a production release.
- System Configuration: Where available, configure the environment to use less verbose error messages. For example, in PHP, disable the display_errors setting during configuration, or at runtime using the error_reporting() function.
- System Configuration: Create default error pages or messages that do not leak any information.
