An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-13816 and fix it if it is affected.\n\nWhat it is: CVE-2018-13816 is a critical authentication bypass vulnerability in Siemens AG TIM 1531 IRC, published on 12 Dec 2018. 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-2018-13816 in the wild and no public exploit code.\n\nAffected product: Siemens AG TIM 1531 IRC. 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-2018-13816/ (Markdown: https://insights.sbomify.com/CVE-2018-13816/index.md)","id":"CVE-2018-13816","markdown":"https://insights.sbomify.com/CVE-2018-13816/index.md","name":"CVE-2018-13816","record":{"aliases":["GHSA-vx39-fw57-q8mc"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens TIM 1531 IRC","requires_auth":"none","summary":"An attacker can bypass authentication on port 102/tcp of the Siemens TIM 1531 IRC device, gaining unauthorized access without user interaction.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"tim_1531_irc_firmware","vendor":"siemens"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability has been identified in TIM 1531 IRC (All version \u003c V2.0).
