Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-19791 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-19791/ (Markdown: https://insights.sbomify.com/CVE-2018-19791/index.md)","id":"CVE-2018-19791","markdown":"https://insights.sbomify.com/CVE-2018-19791/index.md","name":"CVE-2018-19791","record":{"aliases":["GHSA-p7xx-c3fx-mhqh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenLiteSpeed web server","requires_auth":"low_privilege","summary":"An attacker can cause denial of service in OpenLiteSpeed by exploiting improper handling of HTTP Range headers to amplify response sizes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openlitespeed","vendor":"litespeedtech"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The server in LiteSpeed OpenLiteSpeed before 1.5.0 RC6 does not correctly handle requests for byte sequences, allowing an attacker to amplify the response size by requesting the entire response body repeatedly, as demonstrated by an HTTP Range header value beginning with the \"bytes=0-,0-\" substring.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Denial of service in n/a","id":"CVE-2018-19791","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2018-19792"},"packages":[],"prev":{"headline":"Symfony Open Redirect","id":"CVE-2018-19790"},"products":["n/a"],"published":"2018-12-03","related":[{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2020-5519","kev_date_added":null,"published":"2020-01-06"},{"cvss_score":8.8,"headline":"Authenticated Remote Code Execution in OpenLiteSpeed Web Server","id":"CVE-2022-0073","kev_date_added":null,"published":"2022-10-27"},{"cvss_score":8.8,"headline":"Privilege Escalation in OpenLiteSpeed Web Server","id":"CVE-2022-0074","kev_date_added":null,"published":"2022-10-27"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2021-26758","kev_date_added":null,"published":"2021-04-07"},{"cvss_score":7.5,"headline":"Other in n/a","id":"CVE-2023-40518","kev_date_added":null,"published":"2023-08-14"},{"cvss_score":7.5,"headline":"Use after free in n/a","id":"CVE-2015-3890","kev_date_added":null,"published":"2017-09-20"},{"cvss_score":6.7,"headline":"Memory corruption in n/a","id":"CVE-2018-19792","kev_date_added":null,"published":"2018-12-03"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can cause denial of service in OpenLiteSpeed by exploiting improper handling of HTTP Range headers to amplify response sizes.","url":"https://insights.sbomify.com/CVE-2018-19791/"}
