An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-25690 exists.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.0; fixed in 2.4.56\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-2023-25690/ (Markdown: https://insights.sbomify.com/CVE-2023-25690/index.md)","id":"CVE-2023-25690","markdown":"https://insights.sbomify.com/CVE-2023-25690/index.md","name":"CVE-2023-25690","record":{"aliases":["ALPINE-CVE-2023-25690","ALSA-2023:1670","ALSA-2023:1673","AZL-25605","AZL-43903","AZL-45186","BIT-apache-2023-25690","CLEANSTART-2026-XE02231","CLSA-2023-1679943745","DEBIAN-CVE-2023-25690","GHSA-wc6r-9c75-44gq","RHSA-2023:1547","RHSA-2023:1593","RHSA-2023:1596","RHSA-2023:1597","RHSA-2023:1670","RHSA-2023:1672","RHSA-2023:1673","RHSA-2023:1916","RHSA-2023:3292","RLSA-2023:1670","RLSA-2023:1673","SUSE-SU-2023:0803-1","UBUNTU-CVE-2023-25690","USN-5942-2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Attackers can smuggle HTTP requests to bypass access controls and poison caches in specific Apache mod_proxy configurations.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack.\n\nConfigurations are affected when mod_proxy is enabled along with some form of RewriteRule\n or ProxyPassMatch in which a non-specific pattern matches\n some portion of the user-supplied request-target (URL) data and is then\n re-inserted into the proxied request-target using variable \nsubstitution.
