Adobe Campaign Classic contains a vulnerability that allows for information exposure through error messages, specifically affecting versions 18.10.5 and earlier including build 8984. This vulnerability falls under the CWE-209 category of Error Message Information Exposure, where the application reveals sensitive information in error responses that could aid attackers in understanding the system architecture and potentially exploit other weaknesses. The flaw occurs when the system generates error messages that contain internal implementation details, stack traces, or system paths that should remain hidden from end users. When an error occurs during processing, the application does not properly sanitize the error output, allowing malicious actors to gain insights into the underlying system configuration, database structure, or application logic. This information disclosure vulnerability operates at the application layer and can be exploited by attackers who can trigger error conditions through crafted input or manipulation of system parameters. The impact extends beyond simple information gathering as it can provide attackers with critical system details that facilitate more sophisticated attacks such as injection attacks, privilege escalation, or further reconnaissance. The vulnerability affects the context of the current user, meaning that the information exposed could be specific to that user's session or permissions, potentially leading to session hijacking or targeted attacks against individual accounts. From an operational standpoint, this vulnerability represents a significant risk to organizations using Adobe Campaign Classic as it undermines the principle of least privilege and can expose sensitive data that should remain confidential. The error message exposure can occur during various operations including authentication failures, data processing errors, or system configuration issues. Attackers can leverage this vulnerability to map the application's internal structure and identify potential attack vectors. The ATT&CK framework categorizes this under T1212 Exploitation for Credential Access and T1083 File and Directory Discovery, as the information exposure can lead to credential compromise and system reconnaissance. Organizations should implement proper error handling mechanisms that do not expose internal system details, including custom error pages that mask technical information while still providing users with helpful feedback. The vulnerability demonstrates the importance of secure coding practices and proper input validation to prevent error messages from revealing sensitive system information. Additionally, organizations should conduct regular security testing to identify and remediate similar issues in their applications, ensuring that error handling follows security best practices. The remediation involves updating to Adobe Campaign Classic version 19.1 or later, which includes proper error message sanitization and improved security controls. Security teams should also review existing error handling code and implement logging mechanisms that capture error information internally without exposing it to end users. This vulnerability highlights the critical need for comprehensive security testing and the implementation of robust error handling practices that protect against information disclosure attacks while maintaining system usability. The exposure of system details through error messages represents a fundamental security weakness that can significantly increase the attack surface and provide attackers with valuable intelligence for planning more sophisticated exploitation attempts.
