https://nvd.nist.gov/vuln/detail/CVE-2024-4130

T1053.002 – At

1. Technical Attack Analysis:
– Attack Techniques :
– DLL Hijacking : The attacker places a malicious DLL file in a location where the vulnerable application (Lenovo App Store) will load it instead of the legitimate DLL, leading to arbitrary code execution.
– Local Privilege Escalation : Once the malicious DLL is executed, the attacker gains elevated privileges, potentially allowing them to perform unauthorized actions on the system.
– Persistence : The attacker can establish persistence mechanisms to maintain control over the system even after reboots.

– Possible Outcomes of Exploitation :
– Unauthorized access to sensitive data stored on the system.
– Ability to install additional malicious software or backdoors.
– Compromise of system integrity and potential lateral movement within the network.
– Disruption of services or denial-of-service conditions.

2. Mitigation Measures:
– Implement application whitelisting to prevent unauthorized applications from running.
– Regularly update and patch the Lenovo App Store and related components.
– Monitor system logs for unusual DLL loading behaviors.
– Employ least privilege principles to limit user permissions.
– Educate users on the risks of executing untrusted applications.
– Use antivirus and endpoint detection solutions to identify and block malicious DLLs.
– Disable or restrict local administrative rights where possible.
