SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0). The web server of the affected devices contains a vulnerability that may lead to a buffer overflow condition. An attacker could cause this condition on the webserver by sending a specially crafted request. The webserver could stop and not recover anymore.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-122","CWE-787"],"references":["https://cert-portal.siemens.com/productcert/pdf/ssa-139628.pdf","https://cert-portal.siemens.com/productcert/pdf/ssa-139628.pdf"],"products":["siemens:scalance_x200-4pirt_firmware","siemens:scalance_x201-3pirt_firmware","siemens:scalance_x202-2irt_firmware","siemens:scalance_x202-2pirt_firmware","siemens:scalance_x202-2pirt_siplus_net_firmware","siemens:scalance_x204irt_firmware","siemens:scalance_x307-3_firmware","siemens:scalance_x307-3ld_firmware","siemens:scalance_x308-2_firmware","siemens:scalance_x308-2ld_firmware","siemens:scalance_x308-2lh\\+_firmware","siemens:scalance_x308-2lh_firmware","siemens:scalance_x308-2m_firmware","siemens:scalance_x308-2m_ts_firmware","siemens:scalance_x310_firmware","siemens:scalance_x310fe_firmware","siemens:scalance_x320-1fe_firmware","siemens:scalance_x320-3ldfe_firmware","siemens:scalance_xb205-3_firmware","siemens:scalance_xb205-3ld_firmware","siemens:scalance_xb208_firmware","siemens:scalance_xb213-3_firmware","siemens:scalance_xb213-3ld_firmware","siemens:scalance_xb216_firmware","siemens:scalance_xc206-2_firmware","siemens:scalance_xc206-2g_poe__firmware","siemens:scalance_xc206-2g_poe_eec_firmware","siemens:scalance_xc206-2sfp_eec_firmware","siemens:scalance_xc206-2sfp_firmware","siemens:scalance_xc206-2sfp_g_\\(e\\/ip\\)_firmware","siemens:scalance_xc206-2sfp_g_eec_firmware","siemens:scalance_xc206-2sfp_g_firmware","siemens:scalance_xc208_firmware","siemens:scalance_xc208eec_firmware","siemens:scalance_xc208g_\\(e\\/ip\\)_firmware","siemens:scalance_xc208g_eec_firmware","siemens:scalance_xc208g_firmware","siemens:scalance_xc208g_poe_firmware","siemens:scalance_xc216-4c_firmware","siemens:scalance_xc216-4c_g_\\(e\\/ip\\)_firmware","siemens:scalance_xc216-4c_g_eec_firmware","siemens:scalance_xc216-4c_g_firmware","siemens:scalance_xc216_firmware","siemens:scalance_xc216eec_firmware","siemens:scalance_xc224-4c_g_\\(e\\/ip\\)_firmware","siemens:scalance_xc224-4c_g__firmware","siemens:scalance_xc224-4c_g_eec_firmware","siemens:scalance_xc224__firmware","siemens:scalance_xf201-3p_irt_firmware","siemens:scalance_xf202-2p_irt_firmware"],"source":"nvd","synced_at":"2026-10-19T21:14:10.479542811+00:00"},"epss":{"cve":"CVE-2020-25226","score":0.01736,"percentile":0.77691,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
