CVE-2023-45722 in DRYiCE MyXalytics
Summary
by MITRE • 01/03/2024
HCL DRYiCE MyXalytics is impacted by path traversal arbitrary file read vulnerability because it uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory. The product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Potential exploits can completely disrupt or take over the application.

The vulnerability identified as CVE-2023-45722 affects HCL DRYiCE MyXalytics, a business intelligence and analytics platform that enables organizations to process and analyze large datasets. This security flaw represents a critical path traversal vulnerability that fundamentally compromises the application's file system access controls and data integrity mechanisms. The vulnerability stems from the application's improper handling of user-supplied input when constructing file paths, creating a scenario where malicious actors can bypass intended security boundaries and access arbitrary files on the underlying system.
The technical implementation of this vulnerability occurs when the application accepts external input to build file paths without adequate sanitization or validation of special path elements such as directory traversal sequences like "../" or "\..\". This flaw falls under the Common Weakness Enumeration category CWE-22, which specifically addresses improper limitation of a pathname to a restricted directory. The vulnerability allows attackers to manipulate the file path construction logic by injecting sequences that cause the application to resolve file locations outside of the intended restricted parent directory. When the application processes these crafted inputs, it fails to properly neutralize or escape the special path elements, enabling the attacker to navigate beyond the designated boundaries and access sensitive system files, configuration data, or other restricted resources.
The operational impact of this vulnerability extends beyond simple data exposure, as it can lead to complete application compromise and potential system takeover. An attacker who successfully exploits this vulnerability can gain read access to arbitrary files on the server, potentially including database connection files, application configuration settings, user credentials, or other sensitive information. The vulnerability's severity is amplified by the fact that it can be leveraged to disrupt service availability or even execute arbitrary code if the application has write permissions to critical system locations. This type of vulnerability is particularly dangerous in enterprise environments where analytics platforms often have elevated privileges and access to sensitive organizational data.
Security practitioners should implement multiple layers of mitigation to address this vulnerability effectively. The primary defense mechanism involves implementing strict input validation and sanitization for all external inputs used in file path construction, ensuring that directory traversal sequences are properly neutralized or rejected. The application should enforce a robust path normalization process that resolves all relative paths to their absolute equivalents while maintaining strict adherence to the intended directory boundaries. Additionally, implementing proper access controls and privilege separation can limit the damage if an attacker successfully exploits the vulnerability. Organizations should also consider deploying web application firewalls that can detect and block suspicious path traversal patterns, as well as conducting regular security assessments and penetration testing to identify similar vulnerabilities in other components of their infrastructure. This vulnerability aligns with ATT&CK technique T1083 (File and Directory Discovery) and T1566 (Phishing) as attackers may use path traversal to gather information about the target environment and potentially escalate privileges through access to sensitive configuration files or credentials stored in accessible locations.
