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-1999-0450 exists.\n\nAffected product: Microsoft Internet Information 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-1999-0450/ (Markdown: https://insights.sbomify.com/CVE-1999-0450/index.md)","id":"CVE-1999-0450","markdown":"https://insights.sbomify.com/CVE-1999-0450/index.md","name":"CVE-1999-0450","record":{"aliases":["GHSA-9hg3-q33f-m995"],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IIS web server","requires_auth":"none","summary":"An attacker can determine the real file system path of a Perl script by requesting a non-existent URL, exposing internal directory structures.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"internet_information_server","vendor":"microsoft"},{"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":[],"description":"In IIS, an attacker could determine a real path using a request for a non-existent URL that would be interpreted by Perl (perl.exe).","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"1999-01-26","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"1999-01-26","kind":"exploitdb","ref":"19152","stars":null,"title":"Microsoft IIS 5.0 - IISAPI Extension Enumerate Root Web Server Directory"}],"tier":"weaponised"},"has_fix":null,"headline":"Information disclosure in n/a","id":"CVE-1999-0450","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:internet_information_server","products":["microsoft:internet_information_server","microsoft:internet_information_services"],"type":"information_disclosure","year":"1999"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-1999-0451"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-1999-0449"},"products":["n/a"],"published":"2000-02-04","related":[{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2008-0075","kev_date_added":null,"published":"2008-02-12"},{"cvss_score":10,"headline":"Buffer overflow in fpcount.exe in IIS 4.0 with FrontPage Server Extensions allows remote attackers to execute arbitrary commands.","id":"CVE-1999-1376","kev_date_added":null,"published":"2001-09-12"},{"cvss_score":10,"headline":"By default, IIS 4.0 has a virtual directory /IISADMPWD which contains files that can be used as proxies for brute force password attacks, or","id":"CVE-1999-0407","kev_date_added":null,"published":"2000-06-02"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-1999-0874","kev_date_added":null,"published":"2000-06-02"},{"cvss_score":9,"headline":"Memory corruption in n/a","id":"CVE-2009-3023","kev_date_added":null,"published":"2009-08-31"},{"cvss_score":8.5,"headline":"Memory corruption in n/a","id":"CVE-2010-1256","kev_date_added":null,"published":"2010-06-08"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2007-0087","kev_date_added":null,"published":"2007-01-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"An attacker can determine the real file system path of a Perl script by requesting a non-existent URL, exposing internal directory structures.","url":"https://insights.sbomify.com/CVE-1999-0450/"}
