CVE-2025-1350 in Controller
Summary
by MITRE • 09/18/2026
IBM Controller 11.0.0 through 11.0.1 FP7, and 11.1.0 through 11.1.3 FP1 could allow a remote attacker to obtain sensitive information when a detailed technical error message is returned in the browser. This information could be used in further attacks against the system.

The vulnerability identified within IBM Controller versions ranging from 11.0.0 through 11.0.1 FP7, and 11.1.0 through 11.1.3 FP1 represents a classic instance of information disclosure resulting from improper error handling mechanisms. This flaw allows remote attackers to extract sensitive internal system data by triggering specific conditions that cause the application to return detailed technical error messages directly within the browser interface. In secure software design, error responses should be generic and non-descriptive when presented to end-users or external clients, ensuring that underlying stack traces, database queries, file paths, or configuration details are never exposed. The presence of these verbose diagnostic outputs indicates a failure in sanitizing server-side exceptions before they are serialized for transmission over the network, thereby violating fundamental principles of secure coding practices regarding error management and output encoding.
From an operational perspective, this vulnerability poses a significant risk to the confidentiality integrity of the IBM Controller environment. Detailed technical errors often contain breadcrumbs that reveal the internal architecture, such as specific library versions, database schema structures, or server operating system details. An attacker can leverage this information to map out the attack surface more accurately and craft targeted exploits against known vulnerabilities in those specific components. For instance, knowledge of exact software version numbers allows attackers to search for public exploit code tailored to that precise release, while exposure of internal file paths may facilitate local privilege escalation or further remote code execution attempts if combined with other weaknesses like path traversal. This aligns directly with CWE-209, which classifies the generation of an error message that includes sensitive information as a distinct weakness in software security design.
The exploitation vector for this vulnerability is classified under Remote Code Execution and Information Exposure categories within the MITRE ATT&CK framework, specifically mapping to T1598 Phishing for Information and potentially T1078 Valid Accounts if authentication bypasses are involved in triggering the error states. Attackers typically interact with the application through standard web protocols, sending crafted HTTP requests that induce exceptional conditions such as invalid inputs or missing parameters. When the server processes these malformed requests without proper try-catch blocks or custom error pages, it leaks raw diagnostic data back to the client side via HTML responses or JSON payloads visible in browser developer tools. This passive reconnaissance phase is often a precursor to more aggressive attacks, making its mitigation critical for defense-in-depth strategies.
To mitigate this vulnerability, organizations running affected versions of IBM Controller must apply the latest available service packs and patches provided by IBM that address these error handling deficiencies. Beyond immediate patching, administrators should configure web servers like Apache or Nginx in front of the application to intercept HTTP 500-level errors and serve generic custom error pages instead of allowing the backend application to return raw stack traces. Additionally, developers must review global exception handlers within the IBM Controller codebase to ensure that all unhandled exceptions are logged securely on the server side while returning only standardized, user-friendly messages to clients. Regular security audits focusing on CWE-209 and adherence to OWASP guidelines for error handling will help prevent similar information leakage in future updates or custom integrations.
