It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22677 and fix it if it is affected.\n\nWhat it is: CVE-2021-22677 is a high-severity vulnerability in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100, published on 7 May 2021. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22677 in the wild and no public exploit code.\n\nAffected product: SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100. 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-2021-22677/ (Markdown: https://insights.sbomify.com/CVE-2021-22677/index.md)","id":"CVE-2021-22677","markdown":"https://insights.sbomify.com/CVE-2021-22677/index.md","name":"CVE-2021-22677","record":{"aliases":["GHSA-c99v-p88g-44f5"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SimpleLink Wi-Fi SDK","requires_auth":"low_privilege","summary":"An integer overflow in SimpleLink Wi-Fi SDK APIs during network connection allows attackers to cause denial of service or execute arbitrary code.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cc3100_software_development_kit","vendor":"ti"},{"product":"cc3200_software_development_kit","vendor":"ti"},{"product":"simplelink_cc13x0_software_development_kit","vendor":"ti"},{"product":"simplelink_cc13x2_software_development_kit","vendor":"ti"},{"product":"simplelink_cc26xx_software_development_kit","vendor":"ti"},{"product":"simplelink_cc32xx_software_development_kit","vendor":"ti"},{"product":"simplelink_msp432e4_software_development_kit","vendor":"ti"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow exists in the APIs of the host MCU while trying to connect to a WIFI network may lead to issues such as a denial-of-service condition or code execution on the SimpleLink Wi-Fi (MSP432E4 SDK: v4.20.00.12 and prior, CC32XX SDK v4.30.00.06 and prior, CC13X0 SDK versions prior to v4.10.03, CC13X2 and CC26XX SDK versions prior to v4.40.00, CC3200 SDK v1.5.0 and prior, CC3100 SDK v1.3.0 and prior).","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":"Integer overflow in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22677","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Cscape","id":"CVE-2021-22678"},"packages":[],"prev":{"headline":"Cross-site scripting in WebAccess/SCADA","id":"CVE-2021-22676"},"products":["SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100"],"published":"2021-05-07","related":[{"cvss_score":9.8,"headline":"Integer overflow in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22671","kev_date_added":null,"published":"2021-05-07"},{"cvss_score":9.8,"headline":"Integer overflow in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22679","kev_date_added":null,"published":"2021-05-07"},{"cvss_score":8,"headline":"Memory corruption in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22673","kev_date_added":null,"published":"2021-05-07"},{"cvss_score":7.2,"headline":"Integer overflow in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22675","kev_date_added":null,"published":"2021-05-07"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"An integer overflow in SimpleLink Wi-Fi SDK APIs during network connection allows attackers to cause denial of service or execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2021-22677/"}
