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-2011-4877 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-2011-4877/ (Markdown: https://insights.sbomify.com/CVE-2011-4877/index.md)","id":"CVE-2011-4877","markdown":"https://insights.sbomify.com/CVE-2011-4877/index.md","name":"CVE-2011-4877","record":{"aliases":["GHSA-8wq6-wppf-wxxh"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Siemens HMI Runtime","requires_auth":"none","summary":"Remote attackers can crash Siemens HMI runtime applications by sending crafted TCP data when Transfer Mode is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"simatic_hmi_panels","vendor":"siemens"},{"product":"wincc","vendor":"siemens"},{"product":"wincc_flexible","vendor":"siemens"},{"product":"wincc_flexible_runtime","vendor":"siemens"},{"product":"wincc_runtime_advanced","vendor":"siemens"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"HmiLoad in the runtime loader in Siemens WinCC flexible 2004, 2005, 2007, and 2008; WinCC V11 (aka TIA portal); the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime, when Transfer Mode is enabled, allows remote attackers to cause a denial of service (application crash) by sending crafted data over TCP.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-11-28","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-11-28","kind":"exploitdb","ref":"18166","stars":null,"title":"Siemens SIMATIC WinCC Flexible (Runtime) - Multiple Vulnerabilities"}],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2011-4877","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":8,"next":{"headline":"Path traversal in n/a","id":"CVE-2011-4878"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2011-4876"},"products":["n/a"],"published":"2012-02-03","related":[{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2011-4509","kev_date_added":null,"published":"2012-02-03"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2011-4513","kev_date_added":null,"published":"2012-02-03"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2011-4514","kev_date_added":null,"published":"2012-02-03"},{"cvss_score":9.3,"headline":"Auth bypass in n/a","id":"CVE-2011-4508","kev_date_added":null,"published":"2012-02-03"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2011-4875","kev_date_added":null,"published":"2012-02-03"},{"cvss_score":9.3,"headline":"Path traversal in n/a","id":"CVE-2011-4876","kev_date_added":null,"published":"2012-02-03"},{"cvss_score":8.5,"headline":"Information disclosure in n/a","id":"CVE-2011-4879","kev_date_added":null,"published":"2012-02-03"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash Siemens HMI runtime applications by sending crafted TCP data when Transfer Mode is enabled.","url":"https://insights.sbomify.com/CVE-2011-4877/"}
