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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 1% (30-day exploitation probability)+9
Technical severity (high)+6
CISA SSVC: exploitation "poc"+5
Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Gvectors Wpdiscuz, Voltronic Power SNMP Web Pro).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?

CVE-2026-22199 is "Voltronic Power SNMP Web Pro 1.1 Path Traversal via upload.cgi", rated High. It affects Wpdiscuz (Gvectors); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.5 describes technical severity. EPSS 1.01% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
