Barracuda · Barracudadrive · CVE-2020-23834
**Name of the Vulnerable Software and Affected Versions**
BarracudaDrive version 6.5
**Description**
The issue concerns insecure service file permissions in the bd service, allowing local attackers to escalate privileges to admin. This can be achieved by replacing the `%SYSTEMDRIVE%bdbd.exe` file. Upon the computer's next start, the new bd.exe will be executed with LocalSystem privileges.
**Recommendations**
For BarracudaDrive version 6.5, ensure proper file permissions are set for the bd service to prevent unauthorized access and modification of the `%SYSTEMDRIVE%bdbd.exe` file. As a temporary workaround, consider restricting write access to the `%SYSTEMDRIVE%bd` directory to minimize the risk of exploitation.
