CVE-2024-7600 in Unified SecOps Platform
Summary
by MITRE • 08/21/2024
Logsign Unified SecOps Platform Directory Traversal Arbitrary File Deletion Vulnerability. This vulnerability allows remote attackers to delete arbitrary files 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 delete files in the context of root. Was ZDI-CAN-25025.

The CVE-2024-7600 vulnerability represents a critical directory traversal flaw in the Logsign Unified SecOps Platform that enables authenticated remote attackers to perform arbitrary file deletion operations. This vulnerability specifically targets the HTTP API service component that operates on the standard HTTPS port 443, making it particularly dangerous as it leverages the platform's legitimate administrative interface. The flaw stems from insufficient input validation within the file operation handling mechanism, where user-supplied paths are directly utilized without proper sanitization or authorization checks. This allows an attacker who has obtained valid credentials to manipulate file paths and execute destructive operations that can compromise the entire system integrity.
The technical implementation of this vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as directory traversal attacks. The vulnerability operates at the application layer and specifically targets the platform's file system interaction capabilities through its API endpoints. When an authenticated user submits a malicious path parameter to the affected API service, the system fails to validate the input against a whitelist of acceptable paths or properly sanitize the path before executing file deletion operations. This creates an environment where an attacker can traverse directory structures and delete files with root privileges, potentially leading to complete system compromise or data destruction. The vulnerability's exploitation requires only valid authentication credentials, making it particularly concerning as it can be leveraged by both internal malicious actors and external attackers who have obtained legitimate access credentials.
The operational impact of CVE-2024-7600 extends beyond simple file deletion, as it can result in complete system compromise and data loss within organizations relying on the Logsign Unified SecOps Platform. Attackers can leverage this vulnerability to remove critical system files, configuration data, or log files that are essential for system operation and forensic analysis. The root-level execution capability means that the vulnerability can be exploited to delete system binaries, configuration files, or security-related components that would require extensive system restoration efforts. Organizations using this platform may experience service disruptions, compliance violations, and potential data breaches if attackers use this vulnerability to remove security monitoring components or access control files. The impact is particularly severe in security operations centers where the platform serves as a central monitoring and threat detection system, as the deletion of critical files could compromise the entire security infrastructure.
Mitigation strategies for CVE-2024-7600 should focus on immediate patching of the Logsign Unified SecOps Platform to address the input validation flaw in the HTTP API service. Organizations should implement network segmentation to restrict access to the platform's API endpoints and ensure that only authorized administrative systems can communicate with the platform on port 443. The implementation of robust input validation mechanisms, including path normalization and whitelist-based path checking, should be enforced throughout the application's file operation handling code. Additionally, organizations should conduct comprehensive access reviews to ensure that only necessary personnel have administrative credentials and implement principle of least privilege for all user accounts. Monitoring and logging of file operations within the platform should be enhanced to detect any suspicious file deletion activities, and regular security audits should be performed to identify potential unauthorized access attempts. The vulnerability's classification under ATT&CK technique T1485 highlights the importance of implementing defensive measures against data destruction attacks, and organizations should consider implementing additional security controls such as file integrity monitoring and automated incident response procedures to detect and respond to exploitation attempts.
