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-2022-23990 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2022-23990/ (Markdown: https://insights.sbomify.com/CVE-2022-23990/index.md)","id":"CVE-2022-23990","markdown":"https://insights.sbomify.com/CVE-2022-23990/index.md","name":"CVE-2022-23990","record":{"aliases":["A-221256678","ALPINE-CVE-2022-23990","ASB-A-221256678","AZL-8334","CLEANSTART-2026-NB10448","DEBIAN-CVE-2022-23990","GHSA-r3g2-gw56-v728","JLSEC-2025-51","UBUNTU-CVE-2022-23990"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"An integer overflow in the doProlog function of the libexpat XML parsing library can lead to denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"libexpat","vendor":"libexpat_project"},{"product":"communications_metasolv_solution","vendor":"oracle"},{"product":"sinema_remote_connect_server","vendor":"siemens"},{"product":"nessus","vendor":"tenable"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2022-04-28","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-04-28T05:39:11Z","kind":"github_poc","ref":"https://github.com/Satheesh575555/external_expat_AOSP10_r33_CVE-2022-23990","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Integer overflow in n/a","id":"CVE-2022-23990","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora","libexpat_project:libexpat","siemens:sinema_remote_connect_server","tenable:nessus"],"type":"integer_overflow","year":"2022"},"n_packages":0,"n_references":8,"next":{"headline":"Command injection in XCOM Data Transport for Windows, Linux, and UNIX","id":"CVE-2022-23992"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2022-23989"},"products":["n/a"],"published":"2022-01-26","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"An integer overflow in the doProlog function of the libexpat XML parsing library can lead to denial of service.","url":"https://insights.sbomify.com/CVE-2022-23990/"}
