Summary0006651: Kali 2020.1 experiences excessive RAM usage when running bettercap web user interface. Current Kali VM does not have this issue.
Description

This is submitted for informational purposes.

Bettercap web user interface (UI) in Kali 2020.1 (VMware Fusion on a MacOS Catalina 10.15.5) consumes excessive RAM.

Running this command starts the UI:

sudo bettercap -iface eth0 -caplet /usr/share/bettercap/caplets/http-ui.cap

A web server on ports 80 and 8081 are initiated. Upon logging into the UI, the RAM usage increased significantly (into the Gigabytes) rendering the application unusable.

Truncated ps_mem output while running bettercap with the UI:

kali@kali:~$ sudo ps_mem
Private + Shared = RAM used Program

4.0 KiB + 16.0 KiB = 20.0 KiB dconf-service
...
13.5 MiB + 24.9 MiB = 38.4 MiB xfce4-terminal
19.9 MiB + 25.1 MiB = 45.0 MiB systemd-journald
15.7 MiB + 31.2 MiB = 47.0 MiB xfdesktop
24.4 MiB + 53.7 MiB = 78.0 MiB WebExtensions
70.4 MiB + 99.2 MiB = 169.5 MiB Xorg
147.5 MiB + 212.1 MiB = 359.6 MiB firefox-esr
385.9 MiB + 492.2 MiB = 878.2 MiB Web Content (3)
4.6 GiB + 4.6 GiB = 9.3 GiB bettercap

                     11.1 GiB

=================================

Steps To Reproduce

sudo apt install bettercap
sudo bettercap -iface eth0 -caplets /usr/share/bettercap/caplets/http-ui.cap

Upon execution, bettercap displays links to the web interface:

10.11.0.0/24 > 10.11.0.249 » [08:53:26] [sys.log] [inf] https.server starting on https://0.0.0.0:80
10.11.0.0/24 > 10.11.0.249 » [08:53:26] [sys.log] [inf] api.rest api server starting on https://0.0.0.0:8081

Open link http://0.0.0.0:80 and login using default bettercap credentials user/pass. Bettercap UI opens and system RAM usage increases significantly.

Additional Information

Current build:
kali@kali:~$ uname -a
Linux kali 5.4.0-kali4-amd64 0000001 SMP Debian 5.4.19-1kali1 (2020-02-17) x86_64 GNU/Linux
kali@kali:~$ bettercap -version
bettercap v2.28 (built for linux amd64 with go1.14.4)

Using the current Kali VMware build, bettercap runs as expected.
