The vulnerability identified as CVE-2024-47805 affects the Jenkins Credentials Plugin version 1380.va_435002fa_924 and earlier, excluding specific patched versions. This issue represents a critical information disclosure flaw that undermines the fundamental security assumptions of credential management within Jenkins environments. The vulnerability specifically impacts the handling of credentials stored using the SecretBytes type, which are designed to protect sensitive data through encryption mechanisms. When administrators or authorized users access the configuration files of Jenkins items through the REST API or command line interface, the system fails to properly redact encrypted credential values that should remain confidential.
The technical flaw stems from inadequate sanitization of credential data within the plugin's configuration export functionality. When the config.xml files are accessed programmatically through REST API endpoints or CLI commands, the encrypted values of SecretBytes credentials are exposed in plaintext format within the response data. This occurs because the plugin does not implement proper redaction mechanisms when serializing credential information for API responses, effectively bypassing the encryption protections that should safeguard sensitive data. The vulnerability manifests when the system processes configuration requests that include credential information, particularly those involving the SecretBytes type which is commonly used for storing encrypted passwords, tokens, and other sensitive authentication data.
The operational impact of this vulnerability is severe and multifaceted for Jenkins environments. Attackers who can access the REST API or execute CLI commands on systems with vulnerable Jenkins installations can extract encrypted credential values that should remain protected, potentially leading to unauthorized access to external systems, databases, and services that rely on these credentials. The exposure of credential data through API responses creates opportunities for privilege escalation attacks where attackers can leverage stolen credentials to gain access to additional system resources, potentially compromising entire Jenkins infrastructures and the applications they manage. This vulnerability particularly affects organizations that use Jenkins for continuous integration and deployment processes, where credential exposure could lead to supply chain attacks and unauthorized code deployments.
Security implications extend beyond immediate credential exposure to encompass broader system compromise risks. The vulnerability aligns with CWE-200 (Information Exposure) and represents a failure in proper access control and data sanitization practices. From an attacker's perspective, this issue maps to ATT&CK technique T1552.001 (Credentials In Files) and T1078 (Valid Accounts) as it enables unauthorized access to credential data that can then be used for account takeover and lateral movement within networks. Organizations should implement immediate mitigations including upgrading to patched versions of the Jenkins Credentials Plugin, implementing strict API access controls, and monitoring for unauthorized access attempts to configuration endpoints. The vulnerability underscores the critical importance of proper credential handling and redaction mechanisms in security-sensitive applications, particularly those that manage authentication data for automated processes and system integrations.
