CVE-2024-47935 in StellarProtect
Summary
by MITRE • 02/17/2025
Improper Validation of Integrity Check Value vulnerability in TXOne Networks StellarProtect (Legacy Mode), StellarEnforce, and Safe Lock allows an attacker to escalate their privileges in the victim’s device. The attacker needs to hijack the DLL file in advance. This issue affects StellarProtect (Legacy Mode): before 3.2; StellarEnforce: before 3.2; Safe Lock: from 3.0.0 before 3.1.1076. *Note: StellarProtect (Legacy Mode) is the new name for StellarEnforce, they are the same product.

The CVE-2024-47935 vulnerability represents a critical improper validation of integrity check value flaw that specifically targets TXOne Networks StellarProtect (Legacy Mode), StellarEnforce, and Safe Lock products. This vulnerability falls under the CWE-347 category of Improper Verification of Cryptographic Signature, which directly relates to the failure to properly validate digital signatures or integrity checks that are meant to ensure software authenticity and prevent tampering. The vulnerability exists in the authentication and verification mechanisms that these security products employ to validate the integrity of dynamic link library (DLL) files during system operations. This issue is particularly concerning because it enables privilege escalation attacks that can severely compromise the security posture of affected systems.
The technical flaw manifests when the StellarProtect and StellarEnforce systems fail to properly validate the integrity check values associated with DLL files, allowing attackers to manipulate or replace these critical components without proper authorization. This weakness creates a path for attackers to hijack DLL files and subsequently escalate their privileges within the victim's device. The vulnerability affects multiple versions of the software where the integrity verification mechanisms were either absent, insufficiently implemented, or bypassed through specific attack vectors. The attack requires the initial compromise of a DLL file, which then allows for further exploitation and privilege elevation within the system, making it a particularly dangerous weakness in the software's security architecture.
The operational impact of this vulnerability extends beyond simple privilege escalation, creating a significant risk for organizations that rely on these security products for system protection. When an attacker successfully exploits this vulnerability, they can gain elevated privileges that allow them to execute arbitrary code, access sensitive data, modify system configurations, or even establish persistence within the compromised environment. The affected versions span from StellarProtect (Legacy Mode) before 3.2, StellarEnforce before 3.2, and Safe Lock from 3.0.0 before 3.1.1076, indicating that this weakness has been present across multiple releases and potentially affects a wide range of deployed systems. This vulnerability directly maps to ATT&CK technique T1068 which involves exploiting vulnerabilities to escalate privileges, and T1547.001 which covers registry run keys and startup folder abuse, as attackers can leverage this weakness to gain persistent access.
Organizations should prioritize immediate remediation by upgrading to the patched versions of all affected products, specifically ensuring that StellarProtect (Legacy Mode), StellarEnforce, and Safe Lock are updated to versions that properly validate integrity check values. System administrators should implement additional monitoring to detect unauthorized DLL modifications and establish robust integrity checking mechanisms to prevent the hijacking of critical system components. The vulnerability demonstrates the critical importance of proper cryptographic verification and integrity checking in security software, as the failure to validate these mechanisms can create a complete bypass of the intended security protections. Security teams should also conduct thorough assessments of their systems to identify any potential exploitation attempts and ensure that all security controls are properly configured to prevent DLL hijacking attacks, as this vulnerability represents a fundamental weakness in the software's authentication and verification architecture that could be exploited by sophisticated attackers.
