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-2022-24298 in the wild and no public exploit code.\n\nAffected product: FreeOpcUa/freeopcua. 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-2022-24298/ (Markdown: https://insights.sbomify.com/CVE-2022-24298/index.md)","id":"CVE-2022-24298","markdown":"https://insights.sbomify.com/CVE-2022-24298/index.md","name":"CVE-2022-24298","record":{"aliases":["GHSA-3448-h4p5-g6mc"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OPC UA library","requires_auth":"none","summary":"Attackers can cause denial of service in FreeOpcUa by sending multiple CloseSession requests with deleteSubscription set to False, bypassing memory limits.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"freeopcua","vendor":"freeopcua"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"All versions of package freeopcua/freeopcua are vulnerable to Denial of Service (DoS) when bypassing the limitations for excessive memory consumption by sending multiple CloseSession requests with the deleteSubscription parameter equal to False.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of Service (DoS)","id":"CVE-2022-24298","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in pfSense CE and pfSense Plus","id":"CVE-2022-24299"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) NUCs","id":"CVE-2022-24297"},"products":["FreeOpcUa/freeopcua"],"published":"2022-08-23","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Attackers can cause denial of service in FreeOpcUa by sending multiple CloseSession requests with deleteSubscription set to False, bypassing memory limits.","url":"https://insights.sbomify.com/CVE-2022-24298/"}
