Execution with Unnecessary Privileges vulnerability in Bitdefender Endpoint Security Tools, Total Security allows a local attacker to elevate to NT AUTHORITYSystem. Impersonation enables the server thread to perform actions on behalf of the client but within the limits of the clients security context. This issue affects: Bitdefender Endpoint Security Tools versions prior to 7.2.1.65. Bitdefender Total Security versions prior to 25.0.26.
The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Endpoint_security_tools | Bitdefender | * | 7.2.1.65 (excluding) |
| Total_security | Bitdefender | * | 25.0.26 (excluding) |
New weaknesses can be exposed because running with extra privileges, such as root or Administrator, can disable the normal security checks being performed by the operating system or surrounding environment. Other pre-existing weaknesses can turn into security vulnerabilities if they occur while operating at raised privileges. Privilege management functions can behave in some less-than-obvious ways, and they have different quirks on different platforms. These inconsistencies are particularly pronounced if you are transitioning from one non-root user to another. Signal handlers and spawned processes run at the privilege of the owning process, so if a process is running as root when a signal fires or a sub-process is executed, the signal handler or sub-process will operate with root privileges.
