Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-22673 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-2021-22673/ (Markdown: https://insights.sbomify.com/CVE-2021-22673/index.md)","id":"CVE-2021-22673","markdown":"https://insights.sbomify.com/CVE-2021-22673/index.md","name":"CVE-2021-22673","record":{"aliases":["GHSA-pgcp-f457-f4rx"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SimpleLink Wi-Fi SDK","requires_auth":"low_privilege","summary":"Attackers can remotely execute code via stack-based buffer overflow during OTA firmware updates in SimpleLink Wi-Fi SDKs.","user_interaction":"required","vuln_class":"memory_corruption"},"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":8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"The affected product is vulnerable to stack-based buffer overflow while processing over-the-air firmware updates from the CDN server, which may allow an attacker to remotely execute code 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":"Memory corruption in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22673","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in WebAccess/SCADA","id":"CVE-2021-22674"},"packages":[],"prev":{"headline":"Memory corruption in Delta Electronics CNCSoft ScreenEditor","id":"CVE-2021-22672"},"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":7.8,"headline":"Integer overflow in SimpleLink Wi-Fi, MSP432, CC13XX, CC26XX, CC32XX, CC3100","id":"CVE-2021-22677","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":"Attackers can remotely execute code via stack-based buffer overflow during OTA firmware updates in SimpleLink Wi-Fi SDKs.","url":"https://insights.sbomify.com/CVE-2021-22673/"}
