It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-1999-0524 in the wild and no public exploit code.\n\nAffected product: Apple Mac Os X. 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-1999-0524/ (Markdown: https://insights.sbomify.com/CVE-1999-0524/index.md)","id":"CVE-1999-0524","markdown":"https://insights.sbomify.com/CVE-1999-0524/index.md","name":"CVE-1999-0524","record":{"aliases":["AZL-6510","GHSA-5qg4-5cpf-4r9p"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Azure Linux OS","requires_auth":"none","summary":"Remote attackers can obtain sensitive network configuration details like netmask and timestamp from Azure Linux systems via ICMP.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mac_os_x","vendor":"apple"},{"product":"macos","vendor":"apple"},{"product":"ios","vendor":"cisco"},{"product":"hp-ux","vendor":"hp"},{"product":"tru64","vendor":"hp"},{"product":"aix","vendor":"ibm"},{"product":"os2","vendor":"ibm"},{"product":"linux_kernel","vendor":"linux"},{"product":"windows","vendor":"microsoft"},{"product":"netware","vendor":"novell"},{"product":"solaris","vendor":"oracle"},{"product":"sco_unix","vendor":"sco"},{"product":"irix","vendor":"sgi"},{"product":"bsdos","vendor":"windriver"}],"cvss":{"score":4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2024-11-25","github_poc":3,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-11-25T07:28:25Z","kind":"github_poc","ref":"https://github.com/threatlabindonesia/CVE-1999-0524-ICMP-Timestamp-and-Address-Mask-Request-Exploit","stars":3,"title":null},{"date":"2026-07-14T07:18:29Z","kind":"github_poc","ref":"https://github.com/biontdv/CVE-1999-0524-POC","stars":1,"title":"POC of CVE-1999-0524"},{"date":"2025-05-27T10:51:28Z","kind":"github_poc","ref":"https://github.com/Ransc0rp1on/ICMP-Timestamp-POC","stars":0,"title":"A reconnaissance tool to detect CVE-1999-0524 (ICMP Timestamp Disclosure) by automating timestamp extraction via nping or hping3.
