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-2023-25725 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- haproxy (Bitnami): affected all versions; fixed in 2.0.31, 2.2.29, 2.4.22, 2.5.12, 2.6.9, 2.7.3\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-2023-25725/ (Markdown: https://insights.sbomify.com/CVE-2023-25725/index.md)","id":"CVE-2023-25725","markdown":"https://insights.sbomify.com/CVE-2023-25725/index.md","name":"CVE-2023-25725","record":{"aliases":["AZL-13569","BIT-haproxy-2023-25725","CLSA-2024-1733908866","DEBIAN-CVE-2023-25725","DLA-3318-1","GHSA-h2p2-w857-329f","SUSE-SU-2023:0411-1","UBUNTU-CVE-2023-25725","USN-5869-1","USN-7135-1","openSUSE-SU-2024:12686-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HAProxy load balancer","requires_auth":"none","summary":"Attackers can bypass access controls via HTTP request smuggling by exploiting header parsing flaws in HAProxy, potentially hiding headers from security checks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"haproxy","vendor":"haproxy"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations, aka \"request smuggling.\" The HTTP header parsers in HAProxy may accept empty header field names, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1.
