CVE-2021-3029
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 · uneditedEVOLUCARE ECSIMAGING (aka ECS Imaging) through 6.21.5 has an OS Command Injection vulnerability via shell metacharacters and an IFS manipulation. The parameter "file" on the webpage /showfile.php can be exploited to gain root access. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
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 confidenceEVOLUCARE ECSIMAGING through version 6.21.5 contains an OS Command Injection vulnerability in the /showfile.php endpoint. The 'file' parameter accepts shell metacharacters and IFS (Internal Field Separator) manipulation, allowing unauthenticated attackers to execute arbitrary operating system commands with root privileges.

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.
-
Confirm Evolucare Ecs Imaging is installedLocate the application by checking for the Ecs Imaging web root directory (commonly under /var/www, /htdocs, or C:\inetpub), or look for a running web service on typical HTTP/HTTPS ports serving Ecs Imaging content.Affected if The product is found on the system.
-
Determine the installed versionCheck for a version file in the application root, examine the application header or footer displayed in the web interface, or query the application for version information if such an endpoint exists.Affected if The version is 6.21.5 or lower.
-
Verify the /showfile.php endpoint existsAttempt to access the /showfile.php endpoint via HTTP or HTTPS (for example: http://[hostname]/showfile.php). A 200 OK response indicates the endpoint exists and may be vulnerable.Affected if The endpoint returns a valid response rather than a 404 error.
-
Check network exposure of the vulnerable endpointDetermine if the web server hosting Ecs Imaging is accessible from untrusted networks by reviewing firewall rules, NAT configurations, or reverse proxy settings.Affected if The /showfile.php endpoint is reachable from outside the trusted network without authentication.
The system is affected if Evolucare Ecs Imaging version 6.21.5 or lower is installed and the /showfile.php endpoint is accessible over the network, as this allows unauthenticated command injection.

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 · scopedSince the product is no longer supported, the recommended mitigation is to replace ECSIMAGING with a supported alternative or, if immediate replacement is not feasible, isolate the affected system from the network and disable the vulnerable /showfile.php endpoint.
- This vulnerability affects EVOLUCARE ECSIMAGING version 6.21.5 and below, which the vendor has stated is no longer supported.
- There is no vendor-provided patch or upgrade path available for this end-of-life product.
- If this product is still in use, it should be decommissioned and replaced with a supported solution.
- If continued use is absolutely required, implement network segmentation to isolate the affected system and restrict all access to the /showfile.php endpoint via firewall rules or web application firewall configuration.
