An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-30648 in the wild and no public exploit code.\n\nAffected product: Advanced Secure Gateway (ASG) and ProxySG. 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-2021-30648/ (Markdown: https://insights.sbomify.com/CVE-2021-30648/index.md)","id":"CVE-2021-30648","markdown":"https://insights.sbomify.com/CVE-2021-30648/index.md","name":"CVE-2021-30648","record":{"aliases":["GHSA-23p9-49c6-fm5w"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Symantec Secure Gateway","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to execute arbitrary commands, modify configurations, and restart Symantec ASG and ProxySG appliances.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"symantec","cpe":[{"product":"symantec_advanced_secure_gateway_500-10_firmware","vendor":"broadcom"},{"product":"symantec_advanced_secure_gateway_s200-30_firmware","vendor":"broadcom"},{"product":"symantec_advanced_secure_gateway_s200-40_firmware","vendor":"broadcom"},{"product":"symantec_advanced_secure_gateway_s400-20_firmware","vendor":"broadcom"},{"product":"symantec_advanced_secure_gateway_s400-30_firmware","vendor":"broadcom"},{"product":"symantec_advanced_secure_gateway_s400-40_firmware","vendor":"broadcom"},{"product":"symantec_advanced_secure_gateway_s500-20_firmware","vendor":"broadcom"},{"product":"symantec_proxysg","vendor":"broadcom"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The Symantec Advanced Secure Gateway (ASG) and ProxySG web management consoles are susceptible to an authentication bypass vulnerability.
