CVE-2026-22199: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Voltronic Power SNMP Web Pro
Voltronic Power SNMP Web Pro version 1.1 contains a pre-authentication path traversal vulnerability in the upload.cgi endpoint. This flaw allows unauthenticated attackers to read arbitrary files on the device filesystem by using directory traversal sequences in the params parameter. Exploitation can lead to disclosure of sensitive files such as password hashes, which may be cracked offline to gain root-level access and full system compromise. The vulnerability has a high severity with a CVSS score of 8.7. No patch or official fix information is currently provided by the vendor.
AI Analysis
Technical Summary
CVE-2026-22199 is a path traversal vulnerability (CWE-22) in Voltronic Power SNMP Web Pro version 1.1. The vulnerability exists in the upload.cgi endpoint, which improperly limits pathname access, allowing unauthenticated attackers to supply directory traversal sequences via the params parameter. This enables reading of arbitrary files on the device filesystem, including sensitive data like password hashes. Successful exploitation can lead to offline cracking of credentials and root-level system compromise. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality.
Potential Impact
An attacker can read arbitrary files on the affected device without authentication, potentially disclosing sensitive information such as password hashes. This can lead to offline password cracking and full system compromise with root privileges. The vulnerability poses a significant confidentiality and system integrity risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the affected device and monitor for suspicious activity related to the upload.cgi endpoint. Avoid exposing the device to untrusted networks.
