CVE-2016-20055 is a privilege escalation vulnerability discovered in IObit Advanced SystemCare. This flaw allows a local attacker to gain elevated privileges by exploiting an unquoted service path within the AdvancedSystemCareService10 service. The vulnerability affects versions 10.0.2 through 10.0.2, and as of the publication date, no official patch has been released.
CVE-2016-20055 in IObit Advanced SystemCare 10.0.2 presents a local privilege escalation risk. It's an unquoted service path vulnerability within the AdvancedSystemCareService10 service. A local attacker can exploit this by placing a malicious executable in the service path. When the service restarts or the system reboots, this executable will be triggered, running with LocalSystem privileges, allowing the attacker to gain control of the system with those elevated permissions. The lack of quotes in the path allows the attacker to manipulate the service execution, redirecting it to their malicious code. This vulnerability is particularly concerning in environments where users have limited administrative rights but could still be targeted.
Exploitation of CVE-2016-20055 requires local access to the affected system. An attacker needs to place a malicious executable in the AdvancedSystemCareService10 service path. The unquoted path allows the attacker to control which file is executed when the service starts. The success of exploitation depends on the attacker's ability to write to the service path, which often requires administrative privileges or the exploitation of other vulnerabilities to gain access. Once the malicious file is executed with LocalSystem privileges, the attacker can perform arbitrary actions on the system, such as installing malware, stealing data, or taking complete control.

Currently, there is no official patch provided by IObit for CVE-2016-20055. The primary mitigation is to avoid using IObit Advanced SystemCare 10.0.2 until an update is released. As a temporary workaround, restrict access to the service path and monitor the AdvancedSystemCareService10 service activity. Implementing the principle of least privilege, limiting user rights, can also reduce the potential impact of exploitation. Maintaining up-to-date operating systems and security software with the latest patches is crucial to mitigate other vulnerabilities that could be exploited in conjunction with this one. System integrity monitoring and anomaly detection are also recommended practices.
