Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-23093 in the wild and no public exploit code.\n\nAffected product: Freebsd Freebsd. 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-2022-23093/ (Markdown: https://insights.sbomify.com/CVE-2022-23093/index.md)","id":"CVE-2022-23093","markdown":"https://insights.sbomify.com/CVE-2022-23093/index.md","name":"CVE-2022-23093","record":{"aliases":["GHSA-7p28-5p54-rq49"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeBSD ping utility","requires_auth":"low_privilege","summary":"A remote attacker can cause a stack buffer overflow in the FreeBSD ping utility, leading to a denial of service crash.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"ping reads raw IP packets from the network to process responses in the pr_pack() function.  As part of processing a response ping has to reconstruct the IP header, the ICMP header and if present a \"quoted packet,\" which represents the packet that generated an ICMP error.  The quoted packet again has an IP header and an ICMP header.\n\nThe pr_pack() copies received IP and ICMP headers into stack buffers for further processing.  In so doing, it fails to take into account the possible presence of IP option headers following the IP header in either the response or the quoted packet.  When IP options are present, pr_pack() overflows the destination buffer by up to 40 bytes.\n\nThe memory safety bugs described above can be triggered by a remote host, causing the ping program to crash.\n\nThe ping process runs in a capability mode sandbox on all affected versions of FreeBSD and is thus very constrained in how it can interact with the rest of the system at the point where the bug can occur.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-03-02","github_poc":2,"max_poc_stars":10,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-03-02T20:18:54Z","kind":"github_poc","ref":"https://github.com/sh4den/CVE-2022-23093","stars":10,"title":"The FreeBSD ICMP buffer overflow, freebsd buffer overflow poc"},{"date":"2024-03-22T08:38:40Z","kind":"github_poc","ref":"https://github.com/Symbolexe/DrayTek-Exploit","stars":0,"title":"CVE-2022-23093 FreeBSD Stack-Based Overflow"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Stack overflow in ping(8)","id":"CVE-2022-23093","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freebsd:freebsd","products":["freebsd:freebsd"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Libreswan 4.2 through 4.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted IKE","id":"CVE-2022-23094"},"packages":[],"prev":{"headline":"Missing bounds check in 9p message handling","id":"CVE-2022-23092"},"products":["FreeBSD"],"published":"2024-02-15","related":[{"cvss_score":10,"headline":"Memory corruption in FreeBSD","id":"CVE-2018-17160","kev_date_added":null,"published":"2018-12-04"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-3954","kev_date_added":null,"published":"2014-10-27"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2006-4304","kev_date_added":null,"published":"2006-08-24"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2006-0226","kev_date_added":null,"published":"2006-01-19"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2004-0002","kev_date_added":null,"published":"2004-02-03"},{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2001-0969","kev_date_added":null,"published":"2002-03-09"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2001-0388","kev_date_added":null,"published":"2001-09-18"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-28","vendors":["FreeBSD"]},"summary":"A remote attacker can cause a stack buffer overflow in the FreeBSD ping utility, leading to a denial of service crash.","url":"https://insights.sbomify.com/CVE-2022-23093/"}
