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 · unedited
An issue was discovered in Mutare Voice (EVM) 3.x before 3.3.8. The web application suffers from SQL injection on Adminlog.asp, Archivemsgs.asp, Deletelog.asp, Eventlog.asp, and Evmlog.asp.

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 confidence

SQL injection vulnerability in Mutare Voice (EVM) 3.x allows unauthenticated attackers to inject malicious SQL queries via multiple ASP pages (Adminlog.asp, Archivemsgs.asp, Deletelog.asp, Eventlog.asp, Evmlog.asp), potentially enabling data exfiltration or complete database compromise.

MitigationUpgrade to Mutare Voice (EVM) version 3.3.8 or later to obtain the patched code. If immediate patching is not feasible, restrict network access to these administrative ASP endpoints and implement WAF rules as a compensating control.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Mutare Voice version
    Locate the installation directory or check the product About/Version information within the application interface. Common locations include the program installation folder or the web application's footer/version page.
    Affected if The installed version is 3.0.0 through 3.3.7 (any version >= 3.0.0 and < 3.3.8)
  2. Locate vulnerable ASP pages
    Check the web root directory for the presence of Adminlog.asp, Archivemsgs.asp, Deletelog.asp, Eventlog.asp, and Evmlog.asp. These are typically found in the /admin or /eva subdirectories of the web application.
    Affected if Any of these ASP pages exist in the web-accessible directory
  3. Verify network exposure
    Determine if these ASP endpoints are reachable from unauthenticated network locations. Attempt to access one of the vulnerable pages (e.g., http://[host]/[path]/Adminlog.asp) without providing credentials.
    Affected if The pages are accessible without authentication from external/untrusted networks
  4. Review database logs for suspicious queries
    Examine database transaction logs, SQL Server logs, or application audit logs for unusual or malicious SQL syntax within requests targeting the vulnerable ASP pages. Look for patterns like UNION SELECT, OR 1=1, or DROP TABLE.
    Affected if Unexpected SQL injection patterns appear in logs related to these ASP pages

A user is affected if Mutare Voice (EVM) version 3.0.0 through 3.3.7 is installed AND the vulnerable ASP pages (Adminlog.asp, Archivemsgs.asp, Deletelog.asp, Eventlog.asp, Evmlog.asp) are network-accessible without authentication.

Upgrade available Upgrade to 3.3.8 or later
Fixed in 3.3.8
Interim mitigation

Upgrade to Mutare Voice (EVM) version 3.3.8 or later to obtain the patched code. If immediate patching is not feasible, restrict network access to these administrative ASP endpoints and implement WAF rules as a compensating control.

Recommended fix High confidence

3.3.8

  1. 1. Back up the current Mutare Voice installation and its database before proceeding with any upgrade.
  2. 2. Download Mutare Voice version 3.3.8 or later from the official vendor source (www.mutare.com).
  3. 3. Follow Mutare's documented upgrade procedure to install version 3.3.8, ensuring all configuration settings are preserved.
  4. 4. After installation, verify the upgrade was successful by checking the application version.
  5. 5. Test the previously affected pages (Adminlog.asp, Archivemsgs.asp, Deletelog.asp, Eventlog.asp, Evmlog.asp) to confirm the SQL injection vulnerability is remediated.
  6. 6. Monitor the application logs for any suspicious SQL-like activity to ensure no exploitation occurred prior to patching.
