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-2023-40709 in the wild and no public exploit code.\n\nAffected product: OPTO 22 SNAP PAC S1. 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-2023-40709/ (Markdown: https://insights.sbomify.com/CVE-2023-40709/index.md)","id":"CVE-2023-40709","markdown":"https://insights.sbomify.com/CVE-2023-40709/index.md","name":"CVE-2023-40709","record":{"aliases":["GHSA-8frv-2qrv-c3x2"],"analysis":{"component_type":"ics_ot","fix_type":"configuration_change","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"SNAP PAC S1 controller","requires_auth":"none","summary":"An attacker can crash the OPTO 22 SNAP PAC S1 device by flooding it with ICMP requests when the built-in web server is enabled but not fully configured.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Dragos","cpe":[{"product":"snap_pac_s1_firmware","vendor":"opto22"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"An adversary could crash the entire device by sending a large quantity of ICMP requests if the controller has the built-in web server enabled but does not have the built-in web server completely set up and configured for the SNAP PAC S1 Firmware version R10.3b","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":"Uncontrolled Resource Consumption in OPTO 22 SNAP PAC S1 Built-In Web Server","id":"CVE-2023-40709","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in SNAP PAC S1","id":"CVE-2023-40710"},"packages":[],"prev":{"headline":"Improper Access Control in OPTO 22 SNAP PAC S1","id":"CVE-2023-40708"},"products":["SNAP PAC S1"],"published":"2023-08-24","related":[{"cvss_score":8.6,"headline":"Improper Restriction of Excessive Authentication Attempts in OPTO 22 SNAP PAC S1 Built-in Web Server","id":"CVE-2023-40706","kev_date_added":null,"published":"2023-08-24"},{"cvss_score":8.6,"headline":"Weak password requirements in OPTO 22 SNAP PAC S1 Built-in Web Server","id":"CVE-2023-40707","kev_date_added":null,"published":"2023-08-24"},{"cvss_score":6.8,"headline":"Denial of service in SNAP PAC S1","id":"CVE-2023-40710","kev_date_added":null,"published":"2023-08-24"},{"cvss_score":5.8,"headline":"Improper Access Control in OPTO 22 SNAP PAC S1","id":"CVE-2023-40708","kev_date_added":null,"published":"2023-08-24"}],"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":"2024-09-13","vendors":["OPTO 22"]},"summary":"An attacker can crash the OPTO 22 SNAP PAC S1 device by flooding it with ICMP requests when the built-in web server is enabled but not fully configured.","url":"https://insights.sbomify.com/CVE-2023-40709/"}
