Docker Desktop: Improper Neutralization of Special Elements used in a Command
CVE-2023-0628 is a high-severity improper neutralization of special elements used in a command vulnerability in Docker Desktop from Docker, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 4.17.0 as the first without the flaw, so updating Docker Desktop to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Docker Desktop to 4.17.0 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
