CVE-2024-7602 in Unified SecOps Platform
Summary
by MITRE • 08/21/2024
Logsign Unified SecOps Platform Directory Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Logsign Unified SecOps Platform. Authentication is required to exploit this vulnerability.
The specific flaw exists within the HTTP API service, which listens on TCP port 443 by default. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose information in the context of root. Was ZDI-CAN-25027.

The CVE-2024-7602 vulnerability represents a critical directory traversal flaw within the Logsign Unified SecOps Platform that exposes sensitive system information through improper input validation in the HTTP API service. This vulnerability resides in the platform's default HTTPS service listening on TCP port 443, making it accessible to remote attackers who can exploit the weakness without requiring local system access. The vulnerability stems from insufficient sanitization of user-supplied paths before they are processed in file operations, creating a pathway for unauthorized information disclosure that operates with root privileges.
The technical implementation of this vulnerability aligns with CWE-22, which specifically addresses improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks. Attackers can manipulate input parameters to bypass normal file access controls and gain access to files outside the intended directory structure. This weakness allows for arbitrary file reading capabilities, enabling attackers to access configuration files, log data, credential stores, and other sensitive information that should remain protected within the system's restricted file hierarchy. The vulnerability's impact is amplified by the fact that exploitation occurs in the context of root privileges, meaning that successful attacks can provide complete system access and control.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates potential for further exploitation within the compromised environment. Attackers can leverage the disclosed information to identify system configurations, extract sensitive data, and potentially escalate privileges to achieve complete system compromise. The requirement for authentication to exploit this vulnerability means that attackers must first obtain valid credentials, but once achieved, the impact remains severe as the vulnerability operates at the system level. This weakness creates a significant risk for organizations using Logsign Unified SecOps Platform, particularly in environments where the platform handles sensitive security data and system information.
Organizations should implement immediate mitigations including input validation and sanitization of all user-supplied paths before processing file operations, as recommended by the ATT&CK framework's technique T1059.1001 for command and scripting interpreter. The implementation of proper path validation should include canonicalization of file paths, restriction of file access to predefined directories, and enforcement of strict access controls that prevent traversal outside of intended boundaries. Additionally, organizations should review and implement network segmentation to limit access to the affected platform, enforce strong authentication mechanisms, and establish monitoring for suspicious API access patterns that may indicate exploitation attempts. Regular security updates and patch management procedures should be prioritized to address this vulnerability promptly and prevent potential exploitation by threat actors.
