Description
Incorrect default permissions in ArubaSign, affecting versions prior to v4.6.6. The vulnerability is caused by the assignment of inappropriate permissions during the software’s default installation, whereby the main executable and other programme files located in C:\Program Files have excessive permissions for the ‘Everyone’ group. This could allow an unprivileged user to replace the main executable and/or its components with a malicious file, thereby enabling the execution of arbitrary code. In the worst-case scenario, if the malicious code is executed with elevated privileges (such as those of Administrator or SYSTEM), the attacker could escalate privileges and gain full control of the system, compromising both security and data integrity.
