An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2009-0901 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio. 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-2009-0901/ (Markdown: https://insights.sbomify.com/CVE-2009-0901/index.md)","id":"CVE-2009-0901","markdown":"https://insights.sbomify.com/CVE-2009-0901/index.md","name":"CVE-2009-0901","record":{"aliases":["GHSA-5q85-2xfh-7gpf"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft ATL Library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via malformed streams exploiting uninitialized VARIANT handling in the Microsoft Active Template Library.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"visual_c\\+\\+","vendor":"microsoft"},{"product":"visual_studio","vendor":"microsoft"},{"product":"visual_studio_.net","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-457","name":"Use of Uninitialized Variable"}],"description":"The Active Template Library (ATL) in Microsoft Visual Studio .NET 2003 SP1, Visual Studio 2005 SP1 and 2008 Gold, and Visual C++ 2005 SP1 and 2008 Gold and SP1; and Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2; does not prevent VariantClear calls on an uninitialized VARIANT, which allows remote attackers to execute arbitrary code via a malformed stream to an ATL (1) component or (2) control, related to ATL headers and error handling, aka \"ATL Uninitialized Object Vulnerability.\"","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":"Code injection in n/a","id":"CVE-2009-0901","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:visual_studio","products":["microsoft:visual_studio"],"type":"code_injection","year":"2009"},"n_packages":0,"n_references":26,"next":{"headline":"Auth bypass in n/a","id":"CVE-2009-0903"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2009-0900"},"products":["n/a"],"published":"2009-07-29","related":[{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2009-2493","kev_date_added":null,"published":"2009-07-29"},{"cvss_score":6.5,"headline":"Information disclosure in n/a","id":"CVE-2009-2495","kev_date_added":null,"published":"2009-07-29"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2007-0842","kev_date_added":null,"published":"2007-02-13"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via malformed streams exploiting uninitialized VARIANT handling in the Microsoft Active Template Library.","url":"https://insights.sbomify.com/CVE-2009-0901/"}
