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-2025-49812 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected all versions; fixed in 2.4.64\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-2025-49812/ (Markdown: https://insights.sbomify.com/CVE-2025-49812/index.md)","id":"CVE-2025-49812","markdown":"https://insights.sbomify.com/CVE-2025-49812/index.md","name":"CVE-2025-49812","record":{"aliases":["ALPINE-CVE-2025-49812","AZL-65097","AZL-65112","BELL-CVE-2025-49812","BIT-apache-2025-49812","CLSA-2025-1757014860","CLSA-2025-1757014900","CLSA-2025-1757501175","DEBIAN-CVE-2025-49812","GHSA-2mcx-3xj5-wg86","MINI-32jq-cw2q-rj9x","RHSA-2025:14998","RHSA-2025:15036","UBUNTU-CVE-2025-49812","openSUSE-SU-2025:15369-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Man-in-the-middle attackers can hijack HTTP sessions via TLS upgrade in Apache HTTP Server when SSLEngine optional is enabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":7.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade.\n\nOnly configurations using \"SSLEngine optional\" to enable TLS upgrades are affected.
