CVE-2025-6749
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 · uneditedA vulnerability classified as critical was found in huija bicycleSharingServer up to 7b8a3ba48ad618604abd4797d2e7cf3b5ac7625a. Affected by this vulnerability is the function searchAdminMessageShow of the file AdminController.java. The manipulation of the argument Title leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable.
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 confidenceSQL injection vulnerability in the searchAdminMessageShow function of AdminController.java in huija bicycleSharingServer. The Title argument is not properly sanitized before being used in a database query, allowing remote attackers to inject malicious SQL statements.

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 huija bicycleSharingServer installationLocate the application by searching for files named 'bicycleSharingServer', 'AdminController.java', or related application directories on the systemAffected if The huija bicycleSharingServer application is present on the system
-
Determine application versionCheck version information in application configuration files, build manifests (pom.xml, build.gradle), or the application banner/startup logsAffected if The installed version falls within any affected version range for this CVE (compare your version to the affected release timeline)
-
Locate vulnerable AdminController.javaFind the AdminController.java file in the application source code or decompiled classes, then locate the searchAdminMessageShow functionAffected if The file contains the searchAdminMessageShow function with a Title parameter used in database queries
-
Verify admin interface is accessibleCheck network configuration and application routing to determine if the AdminController endpoints are exposed externally or accessible to untrusted usersAffected if The admin interface containing the vulnerable function is reachable from untrusted networks or users
-
Inspect database query implementationExamine the searchAdminMessageShow function code to confirm the Title parameter is concatenated directly into SQL queries without parameterized statements or input sanitizationAffected if The Title parameter is used in raw SQL queries without prepared statements or input validation
You are affected if huija bicycleSharingServer is installed, the vulnerable searchAdminMessageShow function exists in AdminController.java, and the admin interface is accessible with the Title parameter being used in unsanitized SQL queries.

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 or prepared statements for all database interactions involving user-supplied input. Apply input validation and output encoding as defense-in-depth measures.
