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 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.
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, where the params parameter is not properly sanitized, allowing unauthenticated attackers to traverse directories and read arbitrary files on the device filesystem. This can lead to disclosure of sensitive information including password hashes, potentially enabling offline cracking and root-level system compromise. The vulnerability is remotely exploitable without authentication and requires no user interaction.
Potential Impact
Successful exploitation allows an unauthenticated attacker to read arbitrary files on the affected device, including sensitive files such as password hashes. This can lead to offline password cracking and subsequent root-level access, resulting in full system compromise. The vulnerability poses a significant risk to confidentiality and system integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected device and its management interfaces to trusted networks only. Monitor for any updates from Voltronic Power regarding patches or mitigations.
