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-2009-1535 exists.\n\nAffected product: Microsoft Internet Information Services. 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-2009-1535/ (Markdown: https://insights.sbomify.com/CVE-2009-1535/index.md)","id":"CVE-2009-1535","markdown":"https://insights.sbomify.com/CVE-2009-1535/index.md","name":"CVE-2009-1535","record":{"aliases":["CVE-2009-1676","GHSA-f2c7-qmx6-wq66"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"IIS WebDAV","requires_auth":"none","summary":"Remote attackers can bypass WebDAV authentication in IIS to read, create, or modify protected files via crafted Unicode characters in the URI.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"internet_information_services","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The WebDAV extension in Microsoft Internet Information Services (IIS) 5.1 and 6.0 allows remote attackers to bypass URI-based protection mechanisms, and list folders or read, create, or modify files, via a %c0%af (Unicode / character) at an arbitrary position in the URI, as demonstrated by inserting %c0%af into a \"/protected/\" initial pathname component to bypass the password protection on the protected\\ folder, aka \"IIS 5.1 and 6.0 WebDAV Authentication Bypass Vulnerability,\" a different vulnerability than CVE-2009-1122.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2009-05-15","github_poc":0,"max_poc_stars":null,"metasploit":2,"nuclei":0,"refs":[{"date":"2009-05-15","kind":"exploitdb","ref":"8704","stars":null,"title":"Microsoft IIS 6.0 -
