CVE-2021-45477
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 · uneditedImproper Handling of Parameters vulnerability in Bordam Information Technologies Library Automation System allows Collect Data as Provided by Users. This issue affects Library Automation System: before 19.2.
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 confidenceThe Library Automation System before version 19.2 contains an improper handling of parameters vulnerability that allows attackers to supply malicious input which the system processes without proper sanitization. This enables data collection or manipulation through user-supplied parameters, likely via injection vectors such as SQL injection or similar parameter tampering attacks.

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.
-
Identify if Yordam Library Automation System is installedSearch for Yordam-related files, services, or web applications on the system. Common locations include /var/www/, /opt/, or C:\Program Files\ on Windows servers. Check for processes named 'yordam' or related services.Affected if Yordam Library Automation System is found running on the system
-
Determine the installed versionLocate version information in configuration files, about pages, or the application metadata. Check for files like version.txt, config.xml, or look for version strings in the application binaries or web interface.Affected if The installed version is lower than 19.2
-
Check if web interface or user-facing parameter inputs are exposedIdentify if the system exposes a web interface or API endpoints that accept user parameters. Look for HTTP services, web servers, or API endpoints used for library operations such as search, user management, or catalog access.Affected if The web interface or parameter-accepting endpoints are accessible to users or network callers
-
Inspect application logs for suspicious parameter tamperingReview application logs, web server logs, and database logs for unusual or malformed parameter values, SQL syntax in parameter fields, or repeated failed queries that may indicate injection attempts.Affected if Logs show evidence of parameter tampering, SQL injection patterns, or unexpected query behavior
-
Check for unparameterized query implementationsIf access to application source code or configuration is available, examine database query implementations for direct string concatenation of user inputs rather than parameterized queries.Affected if User-supplied parameters are used directly in database queries without parameterization
You are affected if Yordam Library Automation System version below 19.2 is installed and exposes web interfaces or parameter-accepting features to users or network access.

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 · scoped19.2
Upgrade to Library Automation System version 19.2 or later. Additionally, implement proper input validation, parameterized queries, and context-aware output encoding to prevent injection-based attacks.
Version 19.2
- Identify current installed version of Bordam Library Automation System
- Contact Bordam Information Technologies to obtain version 19.2 or later
- Schedule a maintenance window for the upgrade
- Back up current system configuration and data
- Apply version 19.2 upgrade following vendor documentation
- Verify the upgrade was successful and system functions normally
- Monitor logs for any anomalies post-upgrade
