Limit exposure of the affected software until one is available.","what":"CVE-1999-0993 is a high-severity vulnerability in Microsoft Exchange Server, published on 4 Feb 2000."},"fix_prompt":"Check this codebase for CVE-1999-0993 and fix it if it is affected.\n\nWhat it is: CVE-1999-0993 is a high-severity vulnerability in Microsoft Exchange Server, published on 4 Feb 2000. \nExploitation: There is no known exploitation of CVE-1999-0993 in the wild and no public exploit code.\n\nAffected product: Microsoft Exchange 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-1999-0993/ (Markdown: https://insights.sbomify.com/CVE-1999-0993/index.md)","id":"CVE-1999-0993","markdown":"https://insights.sbomify.com/CVE-1999-0993/index.md","name":"CVE-1999-0993","record":{"aliases":["GHSA-r287-63xg-jpw7"],"analysis":null,"analysis_generated_by":null,"assigner":"mitre","cpe":[{"product":"exchange_server","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-665","name":"Improper Initialization"}],"description":"Modifications to ACLs (Access Control Lists) in Microsoft Exchange  5.5 do not take effect until the directory store cache is refreshed.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Modifications to ACLs (Access Control Lists) in Microsoft Exchange 5.5 do not take effect until the directory store cache is refreshed.","id":"CVE-1999-0993","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:exchange_server","products":["microsoft:exchange_server"],"type":null,"year":"1999"},"n_packages":0,"n_references":1,"next":{"headline":"Weak cryptography in n/a","id":"CVE-1999-0994"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-1999-0992"},"products":["n/a"],"published":"2000-02-04","related":[{"cvss_score":9.8,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2024-21410","kev_date_added":"2024-02-15","published":"2024-02-13"},{"cvss_score":9.1,"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-34473","kev_date_added":"2021-11-03","published":"2021-07-14"},{"cvss_score":9.1,"headline":"Microsoft Exchange Server Remote Code Execution","id":"CVE-2021-26855","kev_date_added":"2021-11-03","published":"2021-03-02"},{"cvss_score":9,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2021-34523","kev_date_added":"2021-11-03","published":"2021-07-14"},{"cvss_score":8.8,"headline":"Microsoft Exchange Server Deserialization of Untrusted Data","id":"CVE-2023-21529","kev_date_added":"2026-04-13","published":"2023-02-14"},{"cvss_score":8.8,"headline":"Microsoft Exchange Server Privilege Escalation","id":"CVE-2022-41080","kev_date_added":"2023-01-10","published":"2022-11-09"},{"cvss_score":8.8,"headline":"Microsoft Exchange Server Server-Side Request Forgery","id":"CVE-2022-41040","kev_date_added":"2022-09-30","published":"2022-10-03"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":null,"url":"https://insights.sbomify.com/CVE-1999-0993/"}
