CVE-2026-41551: CWE-23: Relative Path Traversal in Siemens ROS#
CVE-2026-41551 is a critical relative path traversal vulnerability in Siemens ROS# versions prior to 2.2.2. The issue arises from improper sanitization of user input, allowing remote attackers to access arbitrary files on affected devices. The vulnerability has a high CVSS score of 9.1, indicating significant confidentiality and integrity impact without requiring privileges or user interaction. No official patch or remediation guidance is currently confirmed from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability in Siemens ROS# (all versions before 2.2.2) is due to insufficient input validation leading to a relative path traversal (CWE-23). An attacker can exploit this flaw remotely without authentication or user interaction to read arbitrary files on the system, potentially exposing sensitive information or compromising system integrity. The CVSS 3.1 base score is 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), reflecting its critical severity. No official patch or remediation level has been provided by Siemens as of the publication date.
Potential Impact
Successful exploitation allows remote attackers to read arbitrary files on affected devices, compromising confidentiality and integrity of data. This could lead to exposure of sensitive information or further attacks leveraging disclosed data. There is no indication of availability impact. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the Siemens vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to ROS# instances and monitor for suspicious activity related to file access attempts. Avoid exposing vulnerable versions to untrusted networks.
