CVE-2013-4093 in SecureSphere
Summary
by MITRE
The SecureSphere Operations Manager (SOM) Management Server in Imperva SecureSphere 9.0.0.5 allows remote attackers to obtain sensitive information via (1) a direct request to dwr/call/plaincall/AsyncOperationsContainer.getOperationState.dwr, which reveals the installation path in the s0.filePath field, or (2) a T/keyManagement request to plain/settings.html, which reveals a temporary path in an error message.

The vulnerability identified as CVE-2013-4093 affects Imperva SecureSphere 9.0.0.5, specifically targeting the SecureSphere Operations Manager Management Server component. This security flaw represents a classic information disclosure vulnerability that exposes sensitive system details to remote attackers without requiring authentication. The vulnerability manifests through two distinct attack vectors that collectively provide adversaries with valuable reconnaissance information about the target system's configuration and file structure. The primary concern lies in the exposure of installation paths and temporary file locations that could significantly aid in subsequent exploitation attempts.
The technical implementation of this vulnerability stems from inadequate input validation and error handling within the SecureSphere Management Server's web interface. When attackers make direct requests to the dwr/call/plaincall/AsyncOperationsContainer.getOperationState.dwr endpoint, the system responds with a structured data response that inadvertently includes the s0.filePath field containing the installation path. Similarly, when making T/keyManagement requests to plain/settings.html, error messages reveal temporary file paths that provide additional system information. These exposures occur due to the application's failure to properly sanitize output data before returning it to clients, creating an information leakage scenario that violates fundamental security principles.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with critical system intelligence that can be leveraged for more sophisticated attacks. The revealed installation paths could enable attackers to craft targeted exploits specific to the application's deployment environment, while the temporary file paths might expose weaknesses in the system's temporary file handling mechanisms. This information disclosure creates opportunities for attackers to perform reconnaissance, identify potential attack surfaces, and plan more effective exploitation strategies. The vulnerability is particularly concerning because it allows remote attackers to gather sensitive data without requiring any authentication credentials, making it an attractive target for initial reconnaissance phases of cyber attacks.
From a cybersecurity framework perspective, this vulnerability aligns with CWE-200, which addresses "Information Exposure," and represents a clear violation of the principle of least privilege and defense in depth. The ATT&CK framework categorizes this as part of the reconnaissance phase, specifically under T1083 (File and Directory Discovery) and T1592 (Gather Victim Host Information), where adversaries collect information about the target system's configuration and deployment characteristics. The vulnerability demonstrates poor input validation practices and inadequate error handling that directly contribute to information leakage, creating opportunities for attackers to map the target environment and identify potential entry points for further compromise. Organizations should consider this vulnerability as a potential indicator of broader security weaknesses within their application's architecture and input processing mechanisms.
Mitigation strategies for CVE-2013-4093 should focus on implementing proper input validation and output sanitization measures within the SecureSphere Management Server. Organizations should ensure that all web service endpoints properly validate input parameters and sanitize output data before transmission to prevent information leakage. The implementation of proper error handling that does not expose system paths or internal file structures represents a critical security control. Additionally, network segmentation and access controls should be enforced to limit exposure of management interfaces to trusted networks only. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other applications and systems, while applying vendor-provided patches or updates as soon as they become available to remediate this specific information disclosure vulnerability.
