CVE-2025-3245 is a medium severity (CVSS 6.3) SQL injection in itsourcecode Library Management System 1.0. The txtuname argument reaches a database query unsafely in the function Search in library_management/src/Library_Management/Forgot.java. The record names no fixed release, so restrict access, patch the query if you run the code, and check the vendor for updates.
What's affected
itsourcecode Library Management System 1.0, per the CVE record. The record says the issue affects the function Search in library_management/src/Library_Management/Forgot.java, and that manipulating the txtuname argument leads to SQL injection. It says the attack can be launched remotely.
The record also says the exploit has been disclosed publicly and may be used, with a public write-up linked as a reference. It does not say the flaw is exploited in the wild, and the CVE is not on the CISA KEV list.
No fixed version is named. Software of this kind is often published as sample or learning code and may not receive security updates, so look at the project or vendor site for a patch and plan to fix the query yourself if none exists.
How to check if you're exposed
This is a desktop style Java application, so the first step is to see whether it is in use anywhere in your organization. Search source trees and file shares for the project:
grep -rn "txtuname" --include=*.java .
If you find it, read the Search function in Forgot.java and see how the txtuname value reaches the SQL statement. String concatenation is the sign of the problem, and a prepared statement with bound values is the sign of a fix.
Check the database account the application uses and what it can read and change.
What to do now
- Find every copy of the application, including test and demo installs, and decide whether it needs to stay online.
- Take it off the public internet, or put it behind a VPN or authentication layer you control.
- Change the query to a prepared statement with bound parameters, and review the other queries in the same file and project.
- Give the application's database user only the permissions it needs, with no administrative rights.
- Contact the vendor or check the project page for a fixed release, and apply it when it is available.
- If the product is no longer maintained and holds real data, plan a move to a supported alternative.
Why it matters
The classes are CWE-74 (Injection) and CWE-89 (SQL Injection). SQL injection happens when input from a request ends up inside a database query as part of the query text instead of as a separate value. The database cannot tell the developer's query from the caller's input, so the caller can change what the query does. Parameterized queries remove the problem at its source.
Small management systems like this one are often written for learning or for a single customer. They tend to share one habit, which is building queries by joining strings, and that is why several CVEs arrive for one product at once. The fix is a pattern, not a patch: bind every value, in every query.
The record does not mark this CVE as CISA KEV and makes no claim of exploitation in the wild.
Quick check
Does an SQL injection in a small app matter if it holds little data?
Yes. The database account may also be used by other applications, and the host may be reachable from internal networks. The record also says the exploit details are public.
