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-2016-0736 in the wild and no public exploit code.\n\nAffected product: Apache Http Server. 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-2016-0736/ (Markdown: https://insights.sbomify.com/CVE-2016-0736/index.md)","id":"CVE-2016-0736","markdown":"https://insights.sbomify.com/CVE-2016-0736/index.md","name":"CVE-2016-0736","record":{"aliases":["DEBIAN-CVE-2016-0736","GHSA-mxm5-vg5c-rx7v","UBUNTU-CVE-2016-0736"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Apache HTTP Server's mod_session_crypto used unauthenticated encryption modes, allowing attackers to decrypt session data via padding oracle attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"In Apache HTTP Server versions 2.4.0 to 2.4.23, mod_session_crypto was encrypting its data/cookie using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default), hence no selectable or builtin authenticated encryption.
