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-2021-46825 in the wild and no public exploit code.\n\nAffected product: Advance Secure Gateway 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-2021-46825/ (Markdown: https://insights.sbomify.com/CVE-2021-46825/index.md)","id":"CVE-2021-46825","markdown":"https://insights.sbomify.com/CVE-2021-46825/index.md","name":"CVE-2021-46825","record":{"aliases":["GHSA-2h97-8375-29wg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Secure Web Gateway","requires_auth":"none","summary":"Remote attackers can exploit HTTP desync in Symantec ASG and ProxySG to intercept or modify web traffic between clients and servers.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"symantec","cpe":[{"product":"advanced_secure_gateway","vendor":"broadcom"},{"product":"proxysg","vendor":"broadcom"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Symantec Advanced Secure Gateway (ASG) and ProxySG are susceptible to an HTTP desync vulnerability.
