CVE-2025-1809
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 was found in Pixsoft Sol up to 7.6.6c and classified as critical. This issue affects some unknown processing of the file /pix_projetos/servlet?act=login&submit=1&evento=0&pixrnd=0125021816444195731041 of the component Login Endpoint. The manipulation of the argument txtUsuario leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceSQL injection vulnerability in Pixsoft Sol's login endpoint. The txtUsuario parameter in /pix_projetos/servlet accepts unsanitized user input that is directly used in SQL queries, allowing remote attackers to inject malicious SQL commands. This could enable authentication bypass or unauthorized database access.

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 Pixsoft Sol application is runningCheck for processes or services named 'pixsoft' or 'pix_projetos', or scan network for services responding on common web ports that host the /pix_projetos/servlet endpointAffected if The application is running and accessible on the network
-
Verify the vulnerable endpoint existsAttempt to access or probe http[s]://<host>/pix_projetos/servlet to confirm the application exposes this login endpointAffected if The endpoint responds and accepts the txtUsuario parameter
-
Inspect SQL query implementation in login codeReview the source code of the servlet handling the login request, specifically look for SQL queries that incorporate the txtUsuario parameter directly without using PreparedStatement or parameterized queriesAffected if The txtUsuario parameter is concatenated directly into SQL query strings without sanitization or parameterization
-
Check for input validation on txtUsuarioExamine the login handler code to see if txtUsuario undergoes any validation, escaping, or sanitization before being used in database queriesAffected if No input validation, escaping, or sanitization is performed on txtUsuario before SQL execution
-
Confirm database user privilegesReview the database credentials and permissions used by the application login function to determine if the account has elevated privileges beyond what is necessaryAffected if The database user account has excessive privileges that could be exploited if SQL injection occurs
A user is affected if the Pixsoft Sol application is running with the /pix_projetos/servlet endpoint exposed and the txtUsuario parameter is used directly in SQL queries without parameterized statements or input sanitization.

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 dataReplace dynamic SQL queries with parameterized queries/prepared statements for the login functionality. Validate and sanitize all user inputs. Apply the principle of least privilege to database accounts used by the application.
