An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-19837 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-2018-19837/ (Markdown: https://insights.sbomify.com/CVE-2018-19837/index.md)","id":"CVE-2018-19837","markdown":"https://insights.sbomify.com/CVE-2018-19837/index.md","name":"CVE-2018-19837","record":{"aliases":["DEBIAN-CVE-2018-19837","GHSA-c774-r78g-7qj4","UBUNTU-CVE-2018-19837"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"LibSass library","requires_auth":"none","summary":"Attackers can cause denial of service via stack consumption by submitting a crafted Sass file to applications using LibSass.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libsass","vendor":"sass-lang"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In LibSass prior to 3.5.5, Sass::Eval::operator()(Sass::Binary_Expression*) inside eval.cpp allows attackers to cause a denial-of-service resulting from stack consumption via a crafted sass file, because of certain incorrect parsing of '%' as a modulo operator in parser.cpp.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2018-19837","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-19838"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-19836"},"products":["n/a"],"published":"2018-12-04","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2018-11499","kev_date_added":null,"published":"2018-05-26"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2022-26592","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2018-19827","kev_date_added":null,"published":"2018-12-03"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2018-11694","kev_date_added":null,"published":"2018-06-04"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2018-11695","kev_date_added":null,"published":"2018-06-04"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2018-11696","kev_date_added":null,"published":"2018-06-04"},{"cvss_score":8.1,"headline":"Information disclosure in n/a","id":"CVE-2018-11693","kev_date_added":null,"published":"2018-06-04"}],"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":"Attackers can cause denial of service via stack consumption by submitting a crafted Sass file to applications using LibSass.","url":"https://insights.sbomify.com/CVE-2018-19837/"}
