CVE-2020-10199 Sonatype Nexus Repository: command or code injection
In plain words: The program treats text it receives as instructions instead of plain data. The attacker can run commands on the machine — often the whole device is taken over.
Confirmed exploited by CISA on · US federal patch deadline May 3, 2022
What to do
- Install Sonatype's security update for Nexus Repository. If no update exists, follow the vendor's workaround or stop using the product until one ships.

- Patch anything in this catalog first, ahead of normal patch cycles.
- Put admin and file-transfer apps behind a VPN or single sign-on instead of the open internet.
