CVE-2023-31193
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSnap One OvrC Pro versions prior to 7.3 use HTTP connections when downloading a program from their servers. Because they do not use HTTPS, OvrC Pro devices are susceptible to exploitation.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOvrC Pro devices prior to version 7.3 download programs from remote servers using unencrypted HTTP connections instead of HTTPS. This allows man-in-the-middle attackers on the same network to intercept, modify, and inject malicious code into the downloaded programs, potentially leading to arbitrary code execution on the device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check OvrC Pro device firmware versionAccess the device management interface or check system information to identify the currently installed firmware versionAffected if Version is below 7.3.0
-
Verify if remote program download feature is enabledCheck device configuration settings to determine if programs are being downloaded from remote serversAffected if Remote download feature is configured and active
-
Inspect network traffic for HTTP program downloadsMonitor network connections from the device to remote servers on port 80 (HTTP) for program download activityAffected if Device is communicating with remote servers over unencrypted HTTP for program downloads
A user is affected if their OvrC Pro device runs a version lower than 7.3.0 and uses the remote program download feature over unencrypted HTTP connections.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.3.0
Update OvrC Pro devices to version 7.3 or later which implements HTTPS for program downloads. Until updated, ensure devices are on isolated networks away from untrusted users to reduce MITM attack surface.
7.3.0
- 1. Check the current version of OvrC Pro by accessing the device settings or management interface
- 2. Navigate to the software update section in the OvrC Pro administration panel
- 3. Upgrade OvrC Pro to version 7.3.0 or later
- 4. After upgrade, verify that the device now uses HTTPS connections for downloading programs from servers
- 5. Confirm the upgrade was successful by checking the updated version number
