Noroxi assessment

Priority: Monitor (action score 34/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 2% (FIRST EPSS); higher than 81.2% of all records.
Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
Fixed version: docker.io (Debian:10) 18.09.1+dfsg1-7.1+deb10u1; docker.io (Debian:12) 18.09.1+dfsg1-8; docker (Red Hat:rhel_extras_other:7) 2:1.13.1-104.git4ef4b30.el7.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to docker.io (Debian:10) 18.09.1+dfsg1-7.1+deb10u1; docker.io (Debian:12) 18.09.1+dfsg1-8; docker (Red Hat:rhel_extras_other:7) 2:1.13.1-104.git4ef4b30.el7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In Docker before 18.09.4, an attacker who is capable of supplying or manipulating the build path for the "docker build" command would be able to gain command execution. An issue exists in the way "docker build" processes remote git URLs, and results in command injection into the underlying "git clone" command, leading to code execution in the context of the user executing the "docker build" command. This occurs because git ref can be misinterpreted as a flag.
