An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-23308 and fix it if it is affected.\n\nWhat it is: CVE-2020-23308 is a high-severity denial of service vulnerability in Jerryscript Jerryscript, published on 10 Jun 2021. 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-2020-23308 in the wild and no public exploit code.\n\nAffected product: Jerryscript Jerryscript. 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-2020-23308/ (Markdown: https://insights.sbomify.com/CVE-2020-23308/index.md)","id":"CVE-2020-23308","markdown":"https://insights.sbomify.com/CVE-2020-23308/index.md","name":"CVE-2020-23308","record":{"aliases":["GHSA-rjr2-7fwp-m54q","UBUNTU-CVE-2020-23308"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript engine","requires_auth":"none","summary":"A reachable assertion failure in JerryScript allows attackers to cause a denial of service via crafted JavaScript input.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jerryscript","vendor":"jerryscript"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-617","name":"Reachable Assertion"}],"description":"There is an Assertion 'context_p-\u003estack_top_uint8 == LEXER_EXPRESSION_START' at js-parser-expr.c:3565 in parser_parse_expression in JerryScript 2.2.0.","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-2020-23308","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jerryscript:jerryscript","products":["jerryscript:jerryscript"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-23309"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-23306"},"products":["n/a"],"published":"2021-06-10","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-36109","kev_date_added":null,"published":"2023-09-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-38961","kev_date_added":null,"published":"2023-08-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-22597","kev_date_added":null,"published":"2023-07-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-42863","kev_date_added":null,"published":"2022-05-12"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-43453","kev_date_added":null,"published":"2022-04-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-41751","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2021-41752","kev_date_added":null,"published":"2022-04-05"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A reachable assertion failure in JerryScript allows attackers to cause a denial of service via crafted JavaScript input.","url":"https://insights.sbomify.com/CVE-2020-23308/"}
