CVE-2026-1432 Overview
CVE-2026-1432 is a SQL injection vulnerability affecting the Buroweb platform version 2505.0.12. The vulnerability exists specifically within the tablon component, where several parameters fail to properly sanitize user input at the endpoint /sta/CarpetaPublic/doEvent?APP_CODE=STA&PAGE_CODE=TABLON. Successful exploitation of this vulnerability could enable an attacker to execute arbitrary SQL queries against the backend database, potentially leading to unauthorized access to confidential information.
Critical Impact
This unauthenticated SQL injection vulnerability allows remote attackers to extract sensitive data from the database, potentially compromising confidential organizational information stored in the Buroweb platform.
Affected Products
- Buroweb platform version 2505.0.12
- Buroweb tablon component

Technical Details for CVE-2026-1432
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) stems from inadequate input validation in the Buroweb platform's tablon component. The affected endpoint /sta/CarpetaPublic/doEvent?APP_CODE=STA&PAGE_CODE=TABLON accepts user-controlled parameters that are directly incorporated into SQL queries without proper sanitization or parameterization. This classic injection flaw allows attackers to manipulate the structure of SQL queries executed by the application.
The vulnerability is particularly concerning because it can be exploited remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious input containing SQL metacharacters and commands that, when processed by the vulnerable endpoint, execute unintended database operations. This could result in data exfiltration, data manipulation, or further compromise of backend systems.
Root Cause
The root cause of CVE-2026-1432 is the absence of proper input sanitization and parameterized queries in the tablon component. When user input is concatenated directly into SQL statements rather than being properly escaped or passed through prepared statements, the application becomes susceptible to injection attacks. Multiple parameters within the affected endpoint lack these essential security controls, creating multiple attack surfaces for exploitation.
Attack Vector
The attack vector for this vulnerability is network-based, requiring no prior authentication or privileges. An attacker can target the vulnerable endpoint by submitting specially crafted HTTP requests containing malicious SQL syntax within the unsanitized parameters. The injection payload is processed by the application and executed against the database, allowing the attacker to retrieve sensitive information, modify data, or potentially escalate their access depending on the database configuration and permissions.
The exploitation involves sending HTTP requests to the /sta/CarpetaPublic/doEvent endpoint with manipulated parameter values. By injecting SQL commands such as UNION SELECT statements, boolean-based conditions, or time-based payloads, attackers can systematically enumerate database contents, extract credentials, or access other confidential data stored within the system. For detailed technical information, refer to the INCIBE Security Notice.
Detection Methods for CVE-2026-1432
Indicators of Compromise
- Unusual or malformed HTTP requests to /sta/CarpetaPublic/doEvent?APP_CODE=STA&PAGE_CODE=TABLON containing SQL syntax characters such as single quotes, semicolons, or UNION keywords
- Database error messages in web server logs indicating SQL syntax errors or unexpected query behavior
- Anomalous database query patterns or increased query execution times suggesting time-based blind SQL injection attempts
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the vulnerable endpoint
- Implement database activity monitoring to identify suspicious query patterns, including UNION-based data extraction or bulk data access operations
- Review web server access logs for requests containing common SQL injection payloads or encoding obfuscation techniques
Monitoring Recommendations
- Enable verbose logging on the Buroweb application to capture full request parameters for forensic analysis
- Configure SIEM alerts for multiple failed or malformed requests to the tablon component endpoint
- Monitor database account activity for unauthorized data access patterns that may indicate successful exploitation
How to Mitigate CVE-2026-1432
Immediate Actions Required
- Restrict network access to the vulnerable endpoint /sta/CarpetaPublic/doEvent using firewall rules or access control lists until a patch is available
- Deploy WAF rules specifically targeting SQL injection attempts against the Buroweb platform
- Review database logs and application audit trails for evidence of exploitation attempts
Patch Information
Consult the vendor for official patch information regarding Buroweb platform version 2505.0.12. Monitor the INCIBE Security Notice for updates on remediation guidance and any vendor-released security updates.
Workarounds
- Implement input validation at the application or reverse proxy level to filter SQL metacharacters from request parameters
- Deploy a WAF with SQL injection detection capabilities in front of the Buroweb application
- Consider disabling or restricting access to the tablon component if it is not business-critical until a permanent fix is available
