CVE-2026-22199: Voltronic Power SNMP Web Pro 1.1 Path Traversal via upload.cgi

Voltronic Power SNMP Web Pro version 1.1 contains a pre-authentication path traversal vulnerability in the upload.cgi endpoint that allows unauthenticated attackers to read arbitrary files on the device filesystem by supplying directory traversal sequences in the params parameter. Attackers can exploit this vulnerability to disclose sensitive files such as password hashes, which can be cracked offline to obtain root-level access and enable full system compromise.

Security readout for executives and security teams

Plain-English summary

CVE-2026-22199 affects Voltronic Power SNMP Web Pro 1.1. An unauthenticated attacker can abuse a path traversal flaw to read files from the device. The business risk is exposure of sensitive system files, including password hashes, which may enable later full device compromise.

Executive priority

Treat as urgent for any exposed SNMP Web Pro 1.1 device. Prioritize containment of internet-facing management interfaces and vendor guidance review because the flaw requires no login and can disclose credentials useful for deeper compromise.

Technical view

The vulnerability is CWE-22 in the pre-authentication upload.cgi endpoint. The params parameter accepts directory traversal input, allowing arbitrary file read on the device filesystem. The record assigns CVSS 4.0 score 8.7, with network attack vector, low complexity, no privileges, and no user interaction.

Likely exposure

Organizations using Voltronic Power SNMP Web Pro 1.1 are potentially exposed, especially if the web management interface is reachable from untrusted networks. Default status for other versions is unknown in the provided sources.

Exploitation context

The source bundle includes public technical descriptions and a third-party advisory. It is not listed as KEV, and the provided sources do not establish active exploitation in the wild.

Researcher notes

Evidence supports arbitrary file read, not direct code execution for this specific CVE. However, disclosed password hashes may enable offline cracking and root-level access. No patch version is named in the provided sources, so remediation should be guided by vendor or trusted advisory updates.

Mitigation direction

  • Check Voltronic Power and VulnCheck guidance for fixed versions or vendor-recommended mitigations.
  • Restrict SNMP Web Pro web management access to trusted administration networks only.
  • Block internet exposure for affected management interfaces.
  • Rotate credentials if sensitive files may have been exposed.
  • Review device access logs for suspicious upload.cgi requests.

Validation and detection

  • Inventory Voltronic Power SNMP Web Pro deployments and confirm version 1.1 presence.
  • Determine whether the web interface is reachable from the internet or untrusted networks.
  • Review logs for upload.cgi requests containing traversal-style input.
  • Assess whether exposed devices store password hashes or other sensitive local files.
  • Track vendor advisories for patch availability or configuration guidance.
