An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32977 in the wild and no public exploit code.\n\nAffected product: AVEVA System Platform. 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-2021-32977/ (Markdown: https://insights.sbomify.com/CVE-2021-32977/index.md)","id":"CVE-2021-32977","markdown":"https://insights.sbomify.com/CVE-2021-32977/index.md","name":"CVE-2021-32977","record":{"aliases":["GHSA-7v4m-qgj2-p3jc"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"AVEVA System Platform","requires_auth":"high_privilege","summary":"AVEVA System Platform fails to properly verify cryptographic signatures, allowing attackers to bypass security controls.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"system_platform","vendor":"aveva"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"AVEVA System Platform versions 2017 through 2020 R2 P01 does not verify, or incorrectly verifies, the cryptographic signature for data.","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":"AVEVA System Platform Improper Verification of Cryptographic Signature","id":"CVE-2021-32977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Automation Direct CLICK PLC CPU Modules Plaintext Storage of a Password","id":"CVE-2021-32978"},"packages":[],"prev":{"headline":"Moxa NPort IAW5000A-I/O Series Serial Device Server Stack-based Buffer Overflow","id":"CVE-2021-32976"},"products":["AVEVA System Platform"],"published":"2022-04-04","related":[{"cvss_score":8.8,"headline":"AVEVA System Platform Missing Authentication for Critical Function","id":"CVE-2021-33008","kev_date_added":null,"published":"2022-04-04"},{"cvss_score":8.1,"headline":"AVEVA System Platform Cleartext Storage of Sensitive Information in Memory","id":"CVE-2022-0835","kev_date_added":null,"published":"2022-04-11"},{"cvss_score":7.5,"headline":"AVEVA System Platform Uncaught Exception","id":"CVE-2021-33010","kev_date_added":null,"published":"2022-04-04"},{"cvss_score":7.2,"headline":"AVEVA System Platform Path Traversal","id":"CVE-2021-32981","kev_date_added":null,"published":"2022-04-04"},{"cvss_score":7.2,"headline":"AVEVA System Platform Origin Validation Error","id":"CVE-2021-32985","kev_date_added":null,"published":"2022-04-04"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-16","vendors":["AVEVA"]},"summary":"AVEVA System Platform fails to properly verify cryptographic signatures, allowing attackers to bypass security controls.","url":"https://insights.sbomify.com/CVE-2021-32977/"}
