Affected devices use a limited range for challenges that are sent during the unencrypted challenge-response communication. An unauthenticated attacker could capture a valid challenge-response pair generated by a legitimate user, and request the webpage repeatedly to wait for the same challenge to reappear for which the correct response is known. This could allow the attacker to access the management interface of the device.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-294"],"references":["https://cert-portal.siemens.com/productcert/html/ssa-165073.html","https://cert-portal.siemens.com/productcert/html/ssa-471761.html","https://cert-portal.siemens.com/productcert/pdf/ssa-165073.pdf","https://cert-portal.siemens.com/productcert/pdf/ssa-165073.pdf"],"products":["siemens:7kg8500-0aa00-0aa0_firmware","siemens:7kg8500-0aa00-2aa0_firmware","siemens:7kg8500-0aa10-0aa0_firmware","siemens:7kg8500-0aa10-2aa0_firmware","siemens:7kg8500-0aa30-0aa0_firmware","siemens:7kg8500-0aa30-2aa0_firmware","siemens:7kg8501-0aa01-0aa0_firmware","siemens:7kg8501-0aa01-2aa0_firmware","siemens:7kg8501-0aa02-0aa0_firmware","siemens:7kg8501-0aa02-2aa0_firmware","siemens:7kg8501-0aa11-0aa0_firmware","siemens:7kg8501-0aa11-2aa0_firmware","siemens:7kg8501-0aa12-0aa0_firmware","siemens:7kg8501-0aa12-2aa0_firmware","siemens:7kg8501-0aa31-0aa0_firmware","siemens:7kg8501-0aa31-2aa0_firmware","siemens:7kg8501-0aa32-0aa0_firmware","siemens:7kg8501-0aa32-2aa0_firmware","siemens:7kg8550-0aa00-0aa0_firmware","siemens:7kg8550-0aa00-2aa0_firmware","siemens:7kg8550-0aa10-0aa0_firmware","siemens:7kg8550-0aa10-2aa0_firmware","siemens:7kg8550-0aa30-0aa0_firmware","siemens:7kg8550-0aa30-2aa0_firmware","siemens:7kg8551-0aa01-0aa0_firmware","siemens:7kg8551-0aa01-2aa0_firmware","siemens:7kg8551-0aa02-0aa0_firmware","siemens:7kg8551-0aa02-2aa0_firmware","siemens:7kg8551-0aa11-0aa0_firmware","siemens:7kg8551-0aa11-2aa0_firmware","siemens:7kg8551-0aa12-0aa0_firmware","siemens:7kg8551-0aa12-2aa0_firmware","siemens:7kg8551-0aa31-0aa0_firmware","siemens:7kg8551-0aa31-2aa0_firmware","siemens:7kg8551-0aa32-0aa0_firmware","siemens:7kg8551-0aa32-2aa0_firmware"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-29878","score":0.0112,"percentile":0.66176,"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).
