Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43171 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-43171/ (Markdown: https://insights.sbomify.com/CVE-2021-43171/index.md)","id":"CVE-2021-43171","markdown":"https://insights.sbomify.com/CVE-2021-43171/index.md","name":"CVE-2021-43171","record":{"aliases":["GHSA-xqgq-4wpf-xfr8"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"e/OS App Lounge","requires_auth":"low_privilege","summary":"Attackers controlling the server can bypass signature checks to install malicious apps on user devices via the e/OS App Lounge client.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"app_lounge","vendor":"e.foundation"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Improper verification of applications' cryptographic signatures in the /e/OS app store client App Lounge before 0.19q allows attackers in control of the application server to install malicious applications on user's systems by altering the server's API response.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in n/a","id":"CVE-2021-43171","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Infinite length chain of RRDP repositories","id":"CVE-2021-43172"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2021-43164"},"products":["n/a"],"published":"2023-08-22","related":[],"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":"partial"},"state":"PUBLISHED","updated":"2024-10-03","vendors":["n/a"]},"summary":"Attackers controlling the server can bypass signature checks to install malicious apps on user devices via the e/OS App Lounge client.","url":"https://insights.sbomify.com/CVE-2021-43171/"}
