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-2019-13921 in the wild and no public exploit code.\n\nAffected product: Siemens AG SIMATIC WinAC RTX (F) 2010. 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-2019-13921/ (Markdown: https://insights.sbomify.com/CVE-2019-13921/index.md)","id":"CVE-2019-13921","markdown":"https://insights.sbomify.com/CVE-2019-13921/index.md","name":"CVE-2019-13921","record":{"aliases":["GHSA-rf96-4cxg-vq3q"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SIMATIC WinAC RTX","requires_auth":"none","summary":"Unauthenticated attackers can cause a denial of service in SIMATIC WinAC RTX by sending large HTTP requests, impacting service availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_winac_rtx_\\(f\\)_2010","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-410","name":"Insufficient Resource Pool"}],"description":"A vulnerability has been identified in SIMATIC WinAC RTX (F) 2010 (All versions \u003c SP3 Update 1).

The vulnerability can be triggered if a large HTTP request is sent to the executing service. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no system privileges and no user interaction.
