The weakness is an improper privilege escalation vulnerability (CWE\u2011266), which can lead to confidentiality and integrity violations and potentially facilitate further system compromise if exploited successfully.", "risk_and_exploitability": "The CVSS score of 9.9 indicates a critical severity, but the EPSS score of less than 1% suggests a low current exploitation probability. The vulnerability is not listed in the CISA KEV catalog. The likely attack vector is inferred to be remote. An attacker could exploit a software flaw exposed over the device\u2019s network interface or possibly through a local privileged channel if the device is physically accessed. Successful exploitation would allow the attacker to read and modify files on the host, enabling further privilege escalation, persistence, or sabotage of device operation."}}}}, "created": "2026-01-16T14:08:54.437023+00:00", "title": "Unauthorized Access to Host Filesystem via TDC\u2011X401GL Vulnerability", "updated": "2026-04-18T06:15:15.874386+00:00", "vendors": ["sick_ag", "sick_ag$PRODUCT$tdc-x401gl"]}
