An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-54143 in the wild and no public exploit code.\n\nAffected product: openwrt asu. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2024-54143/ (Markdown: https://insights.sbomify.com/CVE-2024-54143/index.md)","id":"CVE-2024-54143","markdown":"https://insights.sbomify.com/CVE-2024-54143/index.md","name":"CVE-2024-54143","record":{"aliases":["GHSA-r3gq-96h6-3v7q"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenWrt build server","requires_auth":"none","summary":"Attackers can poison build artifacts via hash collisions and inject commands to produce malicious firmware images signed with legitimate keys.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-328","name":"Use of Weak Hash"}],"description":"openwrt/asu is an image on demand server for OpenWrt based distributions. The request hashing mechanism truncates SHA-256 hashes to only 12 characters. This significantly reduces entropy, making it feasible for an attacker to generate collisions. By exploiting this, a previously built malicious image can be served in place of a legitimate one, allowing the attacker to \"poison\" the artifact cache and deliver compromised images to unsuspecting users. This can be combined with other attacks, such as a command injection in Imagebuilder that allows malicious users to inject arbitrary commands into the build process, resulting in the production of malicious firmware images signed with the legitimate build key. This has been patched with 920c8a1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"openwrt/asu allows build artifact poisoning via truncated SHA-256 hash and command injection","id":"CVE-2024-54143","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Cacti has a SQL Injection vulnerability when request automation devices","id":"CVE-2024-54145"},"packages":[],"prev":{"headline":"Cross-site Scripting via Discourse-ai SharedAiConversation onebox in Discourse","id":"CVE-2024-54142"},"products":["asu"],"published":"2024-12-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-12-06","vendors":["openwrt"]},"summary":"Attackers can poison build artifacts via hash collisions and inject commands to produce malicious firmware images signed with legitimate keys.","url":"https://insights.sbomify.com/CVE-2024-54143/"}
