Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27855 in the wild and no public exploit code.\n\nAffected product: FatPipe IPVPN. 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-2021-27855/ (Markdown: https://insights.sbomify.com/CVE-2021-27855/index.md)","id":"CVE-2021-27855","markdown":"https://insights.sbomify.com/CVE-2021-27855/index.md","name":"CVE-2021-27855","record":{"aliases":["GHSA-53hg-58mg-7j38"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"FatPipe network software","requires_auth":"low_privilege","summary":"Remote authenticated attackers with read-only access can escalate to administrative privileges in FatPipe network software.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"ipvpn_firmware","vendor":"fatpipeinc"},{"product":"mpvpn_firmware","vendor":"fatpipeinc"},{"product":"warp_firmware","vendor":"fatpipeinc"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"FatPipe WARP, IPVPN, and MPVPN software prior to versions 10.1.2r60p91 and 10.2.2r42 allows a remote, authenticated attacker with read-only privileges to grant themselves administrative privileges.
