CVE-2020-5841
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 · uneditedAn issue was discovered in OpServices OpMon 9.3.1-1. Using password change parameters, an attacker could perform SQL injection without authentication.
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 confidenceOpServices OpMon 9.3.1-1 contains an unauthenticated SQL injection vulnerability in the password change functionality. Attackers can exploit the password change parameters without any authentication to inject malicious SQL queries, potentially allowing full database compromise, data exfiltration, or remote code execution depending on the database configuration.

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.
-
Verify OpMon versionLocate the installed OpMon version through the product's web interface (typically in Help > About or Administration > System Info) or by inspecting version files in the installation directory. Compare the exact version to 9.3.1-1.Affected if The installed version is exactly 9.3.1-1
-
Confirm password change endpoint existsIdentify if the password change functionality is present in the OpMon web interface. This is typically found under user settings, account management, or administrative panels.Affected if The password change functionality is accessible without authentication (the vulnerability allows exploitation without being logged in)
-
Check network exposureDetermine if the OpMon web interface is accessible from untrusted networks or the public internet. Review firewall rules, network ACLs, and VPN configurations restricting access to the OpMon server.Affected if OpMon is directly exposed to the internet or untrusted networks without authentication barriers
You are affected if running OpMon version 9.3.1-1 with the password change feature accessible to unauthenticated users on your network.

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.
From vendor dataUpgrade OpMon to the latest version which contains the patched code. If no patch is available, disable the password change functionality or implement a web application firewall (WAF) rule to block SQL injection patterns in the affected parameters until a fix is applied.
