An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-63033 exists.\n\nAffected product: MZ Automation lib60870. 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-2026-63033/ (Markdown: https://insights.sbomify.com/CVE-2026-63033/index.md)","id":"CVE-2026-63033","markdown":"https://insights.sbomify.com/CVE-2026-63033/index.md","name":"CVE-2026-63033","record":{"aliases":["GHSA-7v97-jmwv-w5j7","GHSA-gqw6-mwcf-3xwh","UBUNTU-CVE-2026-63033"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IEC 60870-5-104 library","requires_auth":"none","summary":"A crafted IEC 60870-5-104 message triggers an out-of-bounds read in lib60870, potentially causing crashes or leaking memory contents.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A crafted IEC 60870-5-104 I-frame with a declared object count exceeding\n what fits in the ASDU body causes InformationObject_ParseObjectAddress \nto read one byte past the end of the heap-allocated message buffer.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"MZ Automation lib60870 Out-of-bounds Read","id":"CVE-2026-63033","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"o6 Automation open62541 Use After Free","id":"CVE-2026-63035"},"packages":[],"prev":{"headline":"WordPress Core Interpretation Conflict","id":"CVE-2026-63030"},"products":["lib60870"],"published":"2026-07-30","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-31","vendors":["MZ Automation"]},"summary":"A crafted IEC 60870-5-104 message triggers an out-of-bounds read in lib60870, potentially causing crashes or leaking memory contents.","url":"https://insights.sbomify.com/CVE-2026-63033/"}
