CVE-2021-29995 in CloverDX
Summary
by MITRE • 06/09/2021
A Cross Site Request Forgery (CSRF) issue in Server Console in CloverDX through 5.9.0 allows remote attackers to execute any action as the logged-in user (including script execution). The issue is resolved in CloverDX 5.10, CloverDX 5.9.1, CloverDX 5.8.2, and CloverDX 5.7.1.

The vulnerability identified as CVE-2021-29995 represents a critical cross site request forgery flaw within the Server Console component of CloverDX software versions up to and including 5.9.0. This vulnerability resides in the web-based administrative interface that administrators use to manage and configure the CloverDX platform, creating a significant attack surface that malicious actors can exploit to gain unauthorized access to system resources and execute arbitrary commands. The flaw specifically affects the Server Console functionality which serves as the primary management interface for administrators to perform various operations including script execution, configuration changes, and system maintenance tasks.
The technical implementation of this CSRF vulnerability stems from the absence of proper anti-forgery token validation mechanisms within the Server Console's web application layer. When a logged-in administrator performs actions through the web interface, the application should validate that requests originate from legitimate user sessions and contain appropriate tokens to prevent unauthorized operations. However, the vulnerable implementation fails to properly verify these security tokens, allowing remote attackers to craft malicious requests that appear to originate from authenticated users. This weakness enables attackers to manipulate the application's behavior by submitting forged requests that execute actions with the privileges of the authenticated user, potentially leading to complete system compromise.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it enables attackers to execute arbitrary scripts and commands on the affected server with the same privileges as the logged-in administrator. This capability provides attackers with extensive control over the CloverDX platform, potentially allowing them to access sensitive data, modify system configurations, install malicious software, or even establish persistent backdoors within the environment. The vulnerability is particularly dangerous because it affects the core administrative console, which typically has elevated privileges and access to critical system functions that could be leveraged to compromise the entire platform. Attackers could exploit this weakness to gain complete control over the data processing and transformation workflows that CloverDX manages, potentially affecting downstream systems and data integrity.
Organizations using affected CloverDX versions should immediately implement mitigation strategies including upgrading to the patched versions 5.10, 5.9.1, 5.8.2, or 5.7.1 as recommended by the vendor. Additionally, network segmentation and access controls should be implemented to limit exposure of the Server Console interface to trusted networks only. The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery, and maps to ATT&CK technique T1078.004 for valid accounts and T1566.001 for spearphishing attachments, as attackers may need to establish initial access before leveraging this CSRF weakness. Organizations should also implement additional monitoring and logging of administrative activities to detect potential exploitation attempts and maintain comprehensive backup strategies to recover from potential compromise scenarios.
