An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-41691 in the wild and no public exploit code.\n\nAffected product: CODESYS Control RTE (SL). 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-2025-41691/ (Markdown: https://insights.sbomify.com/CVE-2025-41691/index.md)","id":"CVE-2025-41691","markdown":"https://insights.sbomify.com/CVE-2025-41691/index.md","name":"CVE-2025-41691","record":{"aliases":["GHSA-wxg9-7gqq-wxgf"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CODESYS Control RTE","requires_auth":"none","summary":"Unauthenticated remote attackers can cause denial of service in CODESYS Control runtime systems via crafted requests triggering a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"An unauthenticated remote attacker may trigger a NULL pointer dereference in the affected CODESYS Control runtime systems by sending specially crafted communication requests, potentially leading to a denial-of-service (DoS) condition.","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":"CODESYS Control DoS via Unauthenticated NULL Pointer Dereference","id":"CVE-2025-41691","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Weak/Predictable root Password","id":"CVE-2025-41692"},"packages":[],"prev":{"headline":"Endress+Hauser: Proline 10 Maintenance credentials may be exposed under certain conditions","id":"CVE-2025-41690"},"products":["Control RTE (SL)","Control RTE (for Beckhoff CX) SL","Control Win (SL)","Control for BeagleBone SL","Control for IOT2000 SL","Control for Linux ARM SL","Control for Linux SL","Control for PFC100 SL","Control for PFC200 SL","Control for PLCnext SL","Control for Raspberry Pi SL","Control for WAGO Touch Panels 600 SL","Control for emPC-A/iMX6 SL","HMI (SL)","Virtual Control SL"],"published":"2025-08-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-08-04","vendors":["CODESYS"]},"summary":"Unauthenticated remote attackers can cause denial of service in CODESYS Control runtime systems via crafted requests triggering a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2025-41691/"}
