Technical details

The ZTE uSmartview Cloud PC client (ZXCloud iRAI) is vulnerable to an uncontrolled search path (CWE-427) involving the openssl.cnf configuration file. Because the application does not properly validate or secure the path from which it loads this configuration, a local attacker can place a malicious configuration file in a directory searched by the application. When the application loads the malicious file, it can be forced to execute arbitrary code or load malicious libraries. This allows a low-privileged local user to escalate their privileges to those of the application, typically administrative or system-level. The vulnerability affects versions from 7.23.20 up to (but excluding) 7.25.43.
