An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-25622 and fix it if it is affected.\n\nWhat it is: CVE-2022-25622 is a medium-severity denial of service vulnerability in Siemens SIMATIC CFU DIQ, published on 12 Apr 2022. 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-2022-25622 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC CFU DIQ. 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-2022-25622/ (Markdown: https://insights.sbomify.com/CVE-2022-25622/index.md)","id":"CVE-2022-25622","markdown":"https://insights.sbomify.com/CVE-2022-25622/index.md","name":"CVE-2022-25622","record":{"aliases":["GHSA-pgxc-2q22-7c2f"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC PLC","requires_auth":"none","summary":"An attacker can cause a denial of service on Siemens SIMATIC devices by sending specially crafted TCP segments to the PROFINET stack.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_cfu_diq_firmware","vendor":"siemens"},{"product":"simatic_cfu_pa_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_firmware","vendor":"siemens"},{"product":"simatic_s7-400_pn\\/dp_v7_firmware","vendor":"siemens"},{"product":"simatic_s7-400h_v6_firmware","vendor":"siemens"},{"product":"simatic_s7-410_v10_firmware","vendor":"siemens"},{"product":"simatic_s7-410_v8_firmware","vendor":"siemens"},{"product":"simatic_tdc_cp51m1_firmware","vendor":"siemens"},{"product":"simatic_tdc_cpu555_firmware","vendor":"siemens"},{"product":"simatic_winac_rtx_firmware","vendor":"siemens"},{"product":"simit_simulation_platform","vendor":"siemens"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The PROFINET (PNIO) stack, when integrated with the Interniche IP stack, improperly handles internal resources for TCP segments where the minimum TCP-Header length is less than defined.\n\nThis could allow an attacker to create a denial of service condition for TCP services on affected devices by sending specially crafted TCP segments.","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":"Denial of service in SIMATIC CFU DIQ","id":"CVE-2022-25622","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in Symantec Management Agent","id":"CVE-2022-25623"},"packages":[],"prev":{"headline":"Command injection in UNIVERGE DT","id":"CVE-2022-25621"},"products":["SIMATIC CFU DIQ","SIMATIC CFU PA","SIMATIC ET 200AL IM 157-1 PN","SIMATIC ET 200MP IM 155-5 PN HF","SIMATIC ET 200S IM 151-8 PN/DP CPU","SIMATIC ET 200S IM 151-8F PN/DP CPU","SIMATIC ET 200SP IM 155-6 MF HF","SIMATIC ET 200SP IM 155-6 PN HA (incl.
