Let’s try with an example: /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin The PATH bash variable ($PATH) contains all the directories (colon-separated) from where binaries can be called without typing the full, you can guess it, path.
In the same days I was working on a script to test for PATH spoofing vulnerabilities so actually one of the first things I thought it would be fun to try was… Spoofing the PATH. Wtf? The VPN client I installed before (Dell’s NetExtender) created a SUID binary! Let’s try something with that. Other than regular system files a thing hit me: 1321668 1 root wheel 18K 16 Apr 17:47 /usr/sbin/uninstallNetExtender sudo find / -user root -perm -4000 -print I decided to start with the basics: let’s scan for suid files. I was at home with nothing to do, so I decided to try to find a vulnerability on OSx (Yosemite back in Sept 2015) as it was a brand new OS for me, so it was a good thing to try. It was a sunny day, outside it was bright and… nah I’m kidding.
Let’s start from the beginning (September 2015) Note: It’s not an 0-day anymore, as I immediately reported the vulnerability to the Dell Security Team as you can see from here: I did try to enable NetBIOS over SSLVPN in SSLVPN|Clients Setting but it does not help.VPN clients are used by most of the IT security experts, to either connect to a ‘restricted’ LAN or to anonymize & secure the traffic or again for many other reasons.īut what happens if a VPN client can lead to a privilege escalation on the machine? Which seems to be the exact same problem, but I don't have any WINS server, so not sure to understand the solution.Īny idea what I need to do to resolve the names over SSL VPN, so that I can connect from home to my machines in the LAN at the office? I can also see the names in Home|Topology)
(Using the name work when I am in the office though, ie not via SSL/VPN. I can ping/ssh machines using their IP in the LAN. I can connect from home from my Win10 laptop to my SonicWall in the office. I set up SSL VPN using with my TZ370 and it was pretty smooth.
