CVE-2013-1402 in DigiLIBE
Summary
by MITRE
DigiLIBE 3.4 and possibly other versions sends a redirect but does not exit, which allows remote attackers to obtain sensitive configuration information via a direct request to configuration/general_configuration.html.

The vulnerability identified as CVE-2013-1402 affects DigiLIBE 3.4 and potentially other versions of the software, representing a critical information disclosure flaw that stems from improper handling of redirect responses. This issue manifests when the application processes requests to the specific endpoint configuration/general_configuration.html, where it fails to properly terminate execution after initiating a redirect response. The flaw resides in the application's web server logic and demonstrates a lack of proper request flow control that creates an exploitable condition for remote attackers.
The technical implementation of this vulnerability involves the application's response handling mechanism where a redirect is issued to the client but the server process continues executing subsequent code paths. This behavior violates standard web application security practices and creates an opportunity for attackers to bypass intended access controls. The configuration/general_configuration.html endpoint likely contains sensitive system parameters, database connection strings, or other administrative settings that should remain protected from unauthorized access. The lack of process termination after redirect allows the application to continue processing the request and potentially expose configuration data that would normally be restricted.
From an operational perspective, this vulnerability presents a significant risk to organizations deploying DigiLIBE software, as it enables remote attackers to obtain sensitive configuration information without requiring authentication or valid session tokens. The impact extends beyond simple information disclosure, as the exposed configuration data may contain credentials, system paths, network configurations, or other details that could facilitate further attacks. Attackers could leverage this information to plan more sophisticated attacks, potentially leading to complete system compromise. The vulnerability's remote exploitability means that attackers can target affected systems from anywhere on the internet without requiring physical access or prior authentication.
Security professionals should note that this vulnerability aligns with CWE-200, which addresses improper exposure of sensitive information, and may also relate to CWE-352, covering cross-site request forgery conditions that could be exploited to manipulate application behavior. The attack vector falls under the MITRE ATT&CK framework's technique T1083, which covers discovery of system information, and potentially T1566, covering phishing attacks that could leverage the exposed configuration data for more targeted social engineering efforts. Organizations should implement immediate mitigations including access control restrictions on sensitive configuration endpoints, input validation to prevent unauthorized access, and application-level logging to detect and monitor suspicious access patterns.
The recommended remediation approach involves updating to patched versions of DigiLIBE software where the redirect handling logic has been corrected to properly terminate execution after redirect responses. Additionally, implementing proper access controls on configuration endpoints, including authentication requirements and IP-based restrictions, would significantly reduce the attack surface. Network segmentation and firewall rules should be configured to limit access to administrative endpoints to only trusted network segments. Regular security assessments and penetration testing should be conducted to identify similar logic flaws in other application components, as this vulnerability demonstrates a pattern of improper state management that could exist in other parts of the application architecture.
