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-2026-102073 in the wild and no public exploit code.\n\nAffected product: Siemens APOGEE MBC (PPC) (BACnet). 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-2026-102073/ (Markdown: https://insights.sbomify.com/CVE-2026-102073/index.md)","id":"CVE-2026-102073","markdown":"https://insights.sbomify.com/CVE-2026-102073/index.md","name":"CVE-2026-102073","record":{"aliases":["GHSA-3jcw-mhf3-39cw"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Building automation controller","requires_auth":"none","summary":"Unauthenticated attackers can exploit an integer overflow in the web service to read device memory or cause denial of service in Siemens building automation controllers.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"A vulnerability has been identified in APOGEE MBC (PPC) (BACnet) (All versions), APOGEE MBC (PPC) (P2 Ethernet) (All versions), APOGEE MEC (PPC) (BACnet) (All versions), APOGEE MEC (PPC) (P2 Ethernet) (All versions), APOGEE PXC Compact (BACnet) (All versions \u003c V3.5.7), APOGEE PXC Compact (P2 Ethernet) (All versions \u003c V2.8.21), APOGEE PXC Modular (BACnet) (All versions \u003c V3.5.7), APOGEE PXC Modular (P2 Ethernet) (All versions \u003c V2.8.21), TALON TC Compact (BACnet) (All versions \u003c V3.5.7), TALON TC Modular (BACnet) (All versions \u003c V3.5.7).
