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-2023-51773 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2023-51773/ (Markdown: https://insights.sbomify.com/CVE-2023-51773/index.md)","id":"CVE-2023-51773","markdown":"https://insights.sbomify.com/CVE-2023-51773/index.md","name":"CVE-2023-51773","record":{"aliases":["GHSA-3j77-72gm-5rj8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"BACnet Stack library","requires_auth":"none","summary":"A buffer over-read in the BACnet Stack library allows attackers to cause denial of service or disclose sensitive memory contents.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bacnet_stack","vendor":"bacnetstack"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"BACnet Stack before 1.3.2 has a decode function APDU buffer over-read in bacapp_decode_application_data in bacapp.c.","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":"Memory corruption in n/a","id":"CVE-2023-51773","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"json-jwt allows bypass of identity checks via a sign/encryption confusion attack","id":"CVE-2023-51774"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2023-51772"},"products":["n/a"],"published":"2023-12-25","related":[{"cvss_score":8.7,"headline":"BACnet Stack: Out-of-Bounds Read in WritePropertyMultiple Decoder via Deprecated Tag Parser","id":"CVE-2026-41475","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":8.7,"headline":"BACnet Stack: Off-by-One Out-of-Bounds Read in ReadPropertyMultiple Object ID Decoder","id":"CVE-2026-41502","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":8.7,"headline":"BACnet Stack: Out-of-Bounds Read in ReadPropertyMultiple Property Decoder via Deprecated Tag Parser","id":"CVE-2026-41503","kev_date_added":null,"published":"2026-04-24"},{"cvss_score":7.8,"headline":"BACnet Stack WriteProperty decoding length underflow leads to OOB read and crash","id":"CVE-2026-26264","kev_date_added":null,"published":"2026-02-13"},{"cvss_score":7.5,"headline":"BACnet Stack Improperly Limits Pathnames to a Restricted Directory","id":"CVE-2026-21878","kev_date_added":null,"published":"2026-02-13"},{"cvss_score":7.5,"headline":"BACnet-stack MS/TP reply matcher OOB read","id":"CVE-2025-66624","kev_date_added":null,"published":"2025-12-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["n/a"]},"summary":"A buffer over-read in the BACnet Stack library allows attackers to cause denial of service or disclose sensitive memory contents.","url":"https://insights.sbomify.com/CVE-2023-51773/"}
