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-2019-13927 in the wild and no public exploit code.\n\nAffected product: Siemens AG Desigo PX automation controllers PXC00-E.D, PXC50-E.D, PXC100-E.D, PXC200-E.D with Desigo PX Web modules PXA40-W0, PXA40-W1, PXA40-W2. 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-2019-13927/ (Markdown: https://insights.sbomify.com/CVE-2019-13927/index.md)","id":"CVE-2019-13927","markdown":"https://insights.sbomify.com/CVE-2019-13927/index.md","name":"CVE-2019-13927","record":{"aliases":["GHSA-3phq-67rm-2hq8"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens Desigo PX controller","requires_auth":"none","summary":"An attacker can cause a denial of service on the web server of Siemens Desigo PX automation controllers by sending a specially crafted HTTP message.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"pxa30-w0_firmware","vendor":"siemens"},{"product":"pxa30-w1_firmware","vendor":"siemens"},{"product":"pxa30-w2_firmware","vendor":"siemens"},{"product":"pxa40-w0_firmware","vendor":"siemens"},{"product":"pxa40-w1_firmware","vendor":"siemens"},{"product":"pxa40-w2_firmware","vendor":"siemens"},{"product":"pxc00-e.d_firmware","vendor":"siemens"},{"product":"pxc00-u_firmware","vendor":"siemens"},{"product":"pxc100-e.d_firmware","vendor":"siemens"},{"product":"pxc128-u_firmware","vendor":"siemens"},{"product":"pxc200-e.d_firmware","vendor":"siemens"},{"product":"pxc22.1-e.d_firmware","vendor":"siemens"},{"product":"pxc36-e.d_firmware","vendor":"siemens"},{"product":"pxc36.1-e.d_firmware","vendor":"siemens"},{"product":"pxc50-e.d_firmware","vendor":"siemens"},{"product":"pxc64-u_firmware","vendor":"siemens"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"},{"id":"CWE-472","name":"External Control of Assumed-Immutable Web Parameter"}],"description":"A vulnerability has been identified in Desigo PX automation controllers PXC00-E.D, PXC50-E.D, PXC100-E.D, PXC200-E.D with Desigo PX Web modules PXA40-W0, PXA40-W1, PXA40-W2 (All firmware versions \u003c V6.00.320), Desigo PX automation controllers PXC00-U, PXC64-U, PXC128-U with Desigo PX Web modules PXA30-W0, PXA30-W1, PXA30-W2 (All firmware versions \u003c V6.00.320), Desigo PX automation controllers PXC22.1-E.D, PXC36-E.D, PXC36.1-E.D with activated web server (All firmware versions \u003c V6.00.320). The device contains a vulnerability that could allow an attacker to cause a denial of service condition on the device's web server by sending a specially crafted HTTP message to the web server port (tcp/80). The security vulnerability could be exploited by an attacker with network access to an affected device. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise the availability of the device's web service. While the device itself stays operational, the web server responds with HTTP status code 404 (Not found) to any further request. A reboot is required to recover the web interface. At the time of advisory publication no public exploitation of this security vulnerability was known.","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 Desigo PX automation controllers PXC00-E.D, PXC50-E.D, PXC100-E.D, PXC200-E.D with Desigo PX Web modules PXA40-W0, PXA40-W1, PXA40-W2","id":"CVE-2019-13927","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Hardcoded credentials in SIMATIC IT UADM","id":"CVE-2019-13929"},"packages":[],"prev":{"headline":"Denial of service in SCALANCE S602","id":"CVE-2019-13926"},"products":["Desigo PX automation controllers PXC00-E.D, PXC50-E.D, PXC100-E.D, PXC200-E.D with Desigo PX Web modules PXA40-W0, PXA40-W1, PXA40-W2","Desigo PX automation controllers PXC00-U, PXC64-U, PXC128-U with Desigo PX Web modules PXA30-W0, PXA30-W1, PXA30-W2","Desigo PX automation controllers PXC22.1-E.D, PXC36-E.D, PXC36.1-E.D with activated web server"],"published":"2019-12-12","related":[],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Siemens AG"]},"summary":"An attacker can cause a denial of service on the web server of Siemens Desigo PX automation controllers by sending a specially crafted HTTP message.","url":"https://insights.sbomify.com/CVE-2019-13927/"}
