An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-4520 exists.\n\nAffected product: n/a. 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-2011-4520/ (Markdown: https://insights.sbomify.com/CVE-2011-4520/index.md)","id":"CVE-2011-4520","markdown":"https://insights.sbomify.com/CVE-2011-4520/index.md","name":"CVE-2011-4520","record":{"aliases":["GHSA-92hc-v7h5-rqc5"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA HMI software","requires_auth":"none","summary":"Remote attackers can cause a denial of service in MICROSYS PROMOTIC via a crafted web page exploiting a heap-based buffer overflow in an ActiveX component.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"promotic","vendor":"microsys"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Heap-based buffer overflow in an ActiveX component in MICROSYS PROMOTIC before 8.1.5 allows remote attackers to cause a denial of service via a crafted web page.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-10-13","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-10-13","kind":"exploitdb","ref":"18049","stars":null,"title":"Microsys PROMOTIC 8.1.4 - ActiveX GetPromoticSite Unitialized Pointer"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2011-4520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in n/a","id":"CVE-2011-4521"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-4519"},"products":["n/a"],"published":"2013-05-23","related":[{"cvss_score":7.9,"headline":"Use after free in n/a","id":"CVE-2011-4874","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2014-9205","kev_date_added":null,"published":"2015-03-29"},{"cvss_score":5,"headline":"Memory corruption in n/a","id":"CVE-2016-0869","kev_date_added":null,"published":"2016-01-26"},{"cvss_score":5,"headline":"Path traversal in n/a","id":"CVE-2011-4518","kev_date_added":null,"published":"2013-05-23"},{"cvss_score":4.3,"headline":"Memory corruption in n/a","id":"CVE-2011-4519","kev_date_added":null,"published":"2013-05-23"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in MICROSYS PROMOTIC via a crafted web page exploiting a heap-based buffer overflow in an ActiveX component.","url":"https://insights.sbomify.com/CVE-2011-4520/"}
