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-2018-8319 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- msrcrypto (npm): affected all versions; fixed in 1.4.1\n- msrcrypto (npm): affected all versions; fixed in 1.4.1\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-2018-8319/ (Markdown: https://insights.sbomify.com/CVE-2018-8319/index.md)","id":"CVE-2018-8319","markdown":"https://insights.sbomify.com/CVE-2018-8319/index.md","name":"CVE-2018-8319","record":{"aliases":["GHSA-qg3g-2mgh-33j8"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript cryptography library","requires_auth":"none","summary":"Incorrect arithmetic computations in the MSR JavaScript Cryptography Library allow attackers to bypass security features.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"research_javascript_cryptography_library","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-682","name":"Incorrect Calculation"}],"description":"A Security Feature Bypass vulnerability exists in MSR JavaScript Cryptography Library that is caused by incorrect arithmetic computations, aka \"MSR JavaScript Cryptography Library Security Feature Bypass Vulnerability.\" This affects Microsoft Research JavaScript Cryptography Library.","ecosystems":["npm"],"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":"Sensitive Data Exposure in msrcrypto","id":"CVE-2018-8319","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"security_feature_bypass","year":"2018"},"n_packages":2,"n_references":3,"next":{"headline":"Security feature bypass in Windows 10","id":"CVE-2018-8320"},"packages":[{"ecosystem":"npm","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"msrcrypto","purl":null,"source":"GHSA-qg3g-2mgh-33j8"},{"ecosystem":"npm","fixed":["1.4.1"],"introduced":["0"],"last_affected":[],"package":"msrcrypto","purl":"pkg:npm/msrcrypto","source":"GHSA-qg3g-2mgh-33j8"}],"prev":{"headline":"Code injection in Internet Explorer 10","id":"CVE-2018-8316"},"products":["Microsoft Research JavaScript Cryptography Library"],"published":"2018-07-11","related":[{"cvss_score":9.8,"headline":"Incorrect Calculation in the MSR JavaScript Cryptography Library","id":"CVE-2020-1026","kev_date_added":null,"published":"2020-04-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":["Microsoft"]},"summary":"Incorrect arithmetic computations in the MSR JavaScript Cryptography Library allow attackers to bypass security features.","url":"https://insights.sbomify.com/CVE-2018-8319/"}
