It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-43896 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- powershell (Bitnami): affected from 7.2.0; fixed in 7.2.1\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-2021-43896/ (Markdown: https://insights.sbomify.com/CVE-2021-43896/index.md)","id":"CVE-2021-43896","markdown":"https://insights.sbomify.com/CVE-2021-43896/index.md","name":"CVE-2021-43896","record":{"aliases":["AZL-7049","BIT-powershell-2021-43896","GHSA-2w8h-77mr-j4fw"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PowerShell","requires_auth":"none","summary":"Attackers can spoof PowerShell content, potentially misleading users or bypassing security checks in Microsoft PowerShell environments.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"powershell","vendor":"microsoft"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"Microsoft PowerShell Spoofing Vulnerability","ecosystems":["Bitnami"],"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":"Microsoft PowerShell Spoofing Vulnerability","id":"CVE-2021-43896","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"other","year":"2021"},"n_packages":1,"n_references":1,"next":{"headline":"Microsoft 4K Wireless Display Adapter Remote Code Execution Vulnerability","id":"CVE-2021-43899"},"packages":[{"ecosystem":"Bitnami","fixed":["7.2.1"],"introduced":["7.2.0"],"last_affected":[],"package":"powershell","purl":"pkg:bitnami/powershell","source":"BIT-powershell-2021-43896"}],"prev":{"headline":"Windows Encrypting File System (EFS) Elevation of Privilege Vulnerability","id":"CVE-2021-43893"},"products":["CBL Mariner 1.0 ARM","CBL Mariner 1.0 x64","CBL Mariner 2.0 ARM","CBL Mariner 2.0 x64","PowerShell 7.2"],"published":"2021-12-15","related":[{"cvss_score":9.8,"headline":"Code injection in PowerShell Editor","id":"CVE-2018-8327","kev_date_added":null,"published":"2018-07-11"},{"cvss_score":8.8,"headline":"Microsoft PowerShell Remote Code Execution Vulnerability","id":"CVE-2026-96251","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":"Microsoft PowerShell Remote Code Execution Vulnerability","id":"CVE-2026-70337","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":8.5,"headline":"PowerShell Remote Code Execution Vulnerability","id":"CVE-2022-41076","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":7.8,"headline":"Microsoft PowerShell Remote Code Execution Vulnerability","id":"CVE-2026-50523","kev_date_added":null,"published":"2026-08-14"},{"cvss_score":7.8,"headline":"Microsoft PowerShell Security Feature Bypass Vulnerability","id":"CVE-2026-70338","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":7.8,"headline":"Microsoft PowerShell Security Feature Bypass Vulnerability","id":"CVE-2026-26143","kev_date_added":null,"published":"2026-04-14"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Microsoft"]},"summary":"Attackers can spoof PowerShell content, potentially misleading users or bypassing security checks in Microsoft PowerShell environments.","url":"https://insights.sbomify.com/CVE-2021-43896/"}
