Description
This security bulletin contains information about 1 vulnerability.
1) Code injection (CVE-ID: N/A)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local low-privileged attacker to gain elevated privileges on the target system.
The weakness exists due to insecure implementation of inter-process communications within the ZoneAlarm application itself. A local attacker can hijack the insecure communications with a vulnerable .NET service that is running with SYSTEM-level privileges, inject and execute arbitrary code to bypass privilege restrictions and gain full control of the system.
Successful exploitation of the vulnerability may result in system compromise.
