CVE-2026-10880
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 · uneditedOSNexus QuantaStor SDS Manager is vulnerable to SQL injection in the login endpoint. The username field is not properly sanitized before being incorporated into a SQL query, allowing an unauthenticated remote attacker to bypass authentication and log in as an administrator without supplying a valid password.
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 · moderate confidenceOSNexus QuantaStor SDS Manager contains a SQL injection vulnerability in the login endpoint where the username field is not properly sanitized before being incorporated into a SQL query. An unauthenticated remote attacker can exploit this to bypass authentication and gain administrator access without supplying a valid password.

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 QuantaStor SDS Manager is installedIdentify if the OSNexus QuantaStor SDS Manager software is running on the system. Look for processes named 'quantastor' or check for the installation directory typically at /usr/local/quantastor or /opt/quantastor.Affected if QuantaStor SDS Manager is installed and running.
-
Determine the installed versionRun the command to retrieve the QuantaStor version, such as 'quanta --version' or check the software version through the management UI under System > About. Compare your version to the affected range.Affected if The installed version falls within any vulnerable version range (if known) or is an unpatched version.
-
Verify network exposure of management interfaceCheck if the QuantaStor management port (typically 443, 8443, or as configured) is exposed to unauthenticated network access. Use 'netstat -tlnp | grep -E "(443|8443)"' or review firewall rules.Affected if The management interface is accessible from untrusted networks without VPN or firewall restrictions.
-
Review authentication logs for admin bypass attemptsExamine QuantaStor authentication logs (typically in /var/log/quantastor/ or through the UI logs) for failed login attempts followed by successful admin logins from the same IP, or for SQL syntax patterns in username fields.Affected if Logs show successful admin logins without corresponding failed attempts, or contain SQL syntax in username fields.
-
Check for unauthorized admin accountsThrough the QuantaStor management UI, review the list of admin users under User Management. Look for unexpected admin accounts or accounts created around the time of potential exploitation.Affected if Unexpected admin accounts exist or admin accounts were created without explicit administrator action.
A system is affected if it runs QuantaStor SDS Manager with a vulnerable version and has its login endpoint exposed to network access where unauthenticated SQL injection could be attempted.

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 dataImplement parameterized queries (prepared statements) for all database queries in the login functionality, or implement proper input validation and sanitization for the username field before using it in SQL queries.
