CVE-2020-13401: An issue was discovered in Docker Engine before 19.03.11.

Noroxi assessment

Priority: Monitor (action score 25/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.8% (FIRST EPSS); higher than 86.7% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: docker.io (Debian:10) 18.09.1+dfsg1-7.1+deb10u2; docker.io (Debian:12) 19.03.11+dfsg1-1; github.com/docker/docker-ce (Go) 19.03.11.
  • Mentioned 6 times 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+deb10u2; docker.io (Debian:12) 19.03.11+dfsg1-1; github.com/docker/docker-ce (Go) 19.03.11 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in Docker Engine before 19.03.11. An attacker in a container, with the CAP_NET_RAW capability, can craft IPv6 router advertisements, and consequently spoof external IPv6 hosts, obtain sensitive information, or cause a denial of service.
