This vulnerability allows Jenkins versions 2.478 and earlier, as well as LTS 2.462.2 and earlier, to expose multi-line secret values in error messages generated for form submissions involving the `secretTextarea` form field. This flaw raises significant concerns about the confidentiality of sensitive information and presents a risk that could be exploited if left unaddressed.
The severity of this vulnerability is categorized as medium, with a CVSS score of 4.3. This classification indicates a moderate risk to organizations, particularly those that handle sensitive data through Jenkins applications. As such, organizations using affected versions should prioritize remediation efforts.
Currently, there is no known public exploit for this vulnerability, but the potential for exploitation remains a concern. Organizations should remain vigilant and ensure they are following best practices for security and data protection.
Organizations should prioritize patching immediately, as this vulnerability could lead to unauthorized access to sensitive information.
Vulnerability Details
The official description states that Jenkins 2.478 and earlier, including 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 vulnerability falls under the CWE classification CWE-209, which is related to information exposure. The medium severity level is significant, as it could lead to the disclosure of sensitive information if not mitigated.
Organizations using affected versions should take immediate action to upgrade to the latest version of Jenkins to ensure protection against this vulnerability.
Technical Analysis
The root cause of this vulnerability is the failure to properly redact sensitive multi-line values from error messages. The attack vector is network-based, meaning an attacker could exploit this vulnerability remotely. The attack complexity is low, and the privileges required to exploit this issue are also low, suggesting that unauthorized users could potentially exploit it.
User interaction is not required to exploit this vulnerability, making it even more critical. The confidentiality impact is categorized as low, while integrity and availability impacts are noted as none.
Risk & Impact Analysis
Risk to organizations includes the potential exposure of sensitive secrets, which could facilitate unauthorized access to systems or data. The vulnerability's medium severity indicates that while immediate exploitation may not be prevalent, the risk of exposure remains significant.
Organizations should assess their deployment of Jenkins and determine if they are using affected versions. The blast radius of this vulnerability could extend to any system or application that relies on Jenkins for its operations.
Given the CVSS score and the current lack of known exploitation, organizations should address this vulnerability in their priority patch cycle.
