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-2006-3747 exists.\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-2006-3747/ (Markdown: https://insights.sbomify.com/CVE-2006-3747/index.md)","id":"CVE-2006-3747","markdown":"https://insights.sbomify.com/CVE-2006-3747/index.md","name":"CVE-2006-3747","record":{"aliases":["DEBIAN-CVE-2006-3747","DSA-1131-1","DSA-1132-1","GHSA-47q7-qpgp-938j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache web server","requires_auth":"none","summary":"Remote attackers can crash the Apache web server or potentially execute arbitrary code via crafted URLs when the RewriteEngine is enabled.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"http_server","vendor":"apache"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":7.6,"severity":"high","source":"nvd","vector":"AV:N/AC:H/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Off-by-one error in the ldap scheme handling in the Rewrite module (mod_rewrite) in Apache 1.3 from 1.3.28, 2.0.46 and other versions before 2.0.59, and 2.2, when RewriteEngine is enabled, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted URLs that are not properly handled using certain rewrite rules.","ecosystems":[],"exploits":{"exploitdb":4,"first_seen":"2006-07-28","github_poc":1,"max_poc_stars":2,"metasploit":1,"nuclei":0,"refs":[{"date":"2016-11-26T00:20:33Z","kind":"github_poc","ref":"https://github.com/defensahacker/CVE-2006-3747","stars":2,"title":"Information about my advisory on CVE-2006-3747 (Apache mod_rewrite LDAP off-by-one buffer overflow)..
