An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-15157 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/containerd/containerd (Go): affected all versions; fixed in 1.2.14\n- github.com/containerd/containerd (Go): affected all versions; fixed in 1.2.14\n- github.com/containerd/containerd (Go): affected all versions; fixed in 1.2.14\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-15157/ (Markdown: https://insights.sbomify.com/CVE-2020-15157/index.md)","id":"CVE-2020-15157","markdown":"https://insights.sbomify.com/CVE-2020-15157/index.md","name":"CVE-2020-15157","record":{"aliases":["DEBIAN-CVE-2020-15157","GHSA-742w-89gc-8m9c","GO-2022-0803","MGASA-2020-0406","UBUNTU-CVE-2020-15157","USN-4589-1","USN-4589-2"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"container runtime","requires_auth":"none","summary":"Attackers can steal registry or cloud credentials by tricking users into pulling malicious container images with foreign layer URLs.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"containerd","vendor":"linuxfoundation"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"In containerd (an industry-standard container runtime) before version 1.2.14 there is a credential leaking vulnerability. If a container image manifest in the OCI Image format or Docker Image V2 Schema 2 format includes a URL for the location of a specific image layer (otherwise known as a “foreign layer”), the default containerd resolver will follow that URL to attempt to download it. In v1.2.x but not 1.3.0 or later, the default containerd resolver will provide its authentication credentials if the server where the URL is located presents an HTTP 401 status code along with registry-specific HTTP headers. If an attacker publishes a public image with a manifest that directs one of the layers to be fetched from a web server they control and they trick a user or system into pulling the image, they can obtain the credentials used for pulling that image. In some cases, this may be the user's username and password for the registry. In other cases, this may be the credentials attached to the cloud virtual instance which can grant access to other cloud resources in the account. The default containerd resolver is used by the cri-containerd plugin (which can be used by Kubernetes), the ctr development tool, and other client programs that have explicitly linked against it. This vulnerability has been fixed in containerd 1.2.14. containerd 1.3 and later are not affected. If you are using containerd 1.3 or later, you are not affected. If you are using cri-containerd in the 1.2 series or prior, you should ensure you only pull images from trusted sources. Other container runtimes built on top of containerd but not using the default resolver (such as Docker) are not affected.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"containerd can be coerced into leaking credentials during image pull","id":"CVE-2020-15157","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux"],"type":"information_disclosure","year":"2020"},"n_packages":3,"n_references":5,"next":{"headline":"Heap buffer overflow in libIEC61850","id":"CVE-2020-15158"},"packages":[{"ecosystem":"Go","fixed":["1.2.14"],"introduced":["0"],"last_affected":[],"package":"github.com/containerd/containerd","purl":null,"source":"GHSA-742w-89gc-8m9c"},{"ecosystem":"Go","fixed":["1.2.14"],"introduced":["0"],"last_affected":[],"package":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","source":"GHSA-742w-89gc-8m9c"},{"ecosystem":"Go","fixed":["1.2.14"],"introduced":["0"],"last_affected":[],"package":"github.com/containerd/containerd","purl":"pkg:golang/github.com/containerd/containerd","source":"GO-2022-0803"}],"prev":{"headline":"XSS due to lack of CSRF validation for replying/publishing","id":"CVE-2020-15156"},"products":["containerd"],"published":"2020-10-16","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["containerd"]},"summary":"Attackers can steal registry or cloud credentials by tricking users into pulling malicious container images with foreign layer URLs.","url":"https://insights.sbomify.com/CVE-2020-15157/"}
