CVE-2020-9015
Arista DCS-7050QX-32S-R 4.20.9M, DCS-7050CX3-32S-R 4.20.11M, and DCS-7280SRAM-48C6-R 4.22.0.1F devices (and possibly other products) allow attackers to bypass intended TACACS+ shell restrictions via a | character.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 16.5%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
