CVE-2026-1478 in Evaluación de Desempeño
Summary
by MITRE • 01/27/2026
An out-of-band SQL injection vulnerability (OOB SQLi) has been detected in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. Exploiting this vulnerability in the parameter 'Id_usuario' and 'Id_evaluacion’ in ‘/evaluacion_hca_evalua.aspx’, could allow an attacker to extract sensitive information from the database through external channels, without the affected application returning the data directly, compromising the confidentiality of the stored information.

The vulnerability identified as CVE-2026-1478 represents a critical out-of-band sql injection flaw within the Performance Evaluation application developed by Gabinete Técnico de Programación. This specific weakness manifests in the web application's handling of user input parameters, particularly affecting the 'Id_usuario' and 'Id_evaluacion' fields within the '/evaluacion_hca_evalua.aspx' endpoint. The out-of-band nature of this vulnerability distinguishes it from traditional sql injection attacks where malicious payloads are typically executed and their results returned directly through the application's response. Instead, this vulnerability enables attackers to leverage external communication channels to exfiltrate data from the database, making detection more challenging and the attack more sophisticated.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the application's backend processing logic. When the application processes the 'Id_usuario' and 'Id_evaluacion' parameters, it fails to properly escape or parameterize user-supplied data before incorporating it into sql queries. This allows an attacker to inject malicious sql payloads that can trigger database operations through external channels, bypassing traditional defensive mechanisms that monitor direct response data. The vulnerability operates under CWE-643, which specifically addresses insufficient input validation in sql contexts, while also aligning with ATT&CK technique T1566.001 for initial access through spearphishing attachments and T1071.004 for application layer protocol usage.
The operational impact of this vulnerability extends beyond simple data theft, as it fundamentally compromises the confidentiality of sensitive information stored within the application's database. Attackers exploiting this vulnerability can extract user credentials, performance evaluation records, personal information, and potentially system configuration details through external dns or http requests that are initiated by the vulnerable database server. The out-of-band nature of the attack means that the malicious data extraction occurs through secondary channels, making it difficult for network monitoring tools to detect the compromise as it doesn't appear in the primary application response streams. This characteristic significantly increases the risk to the organization's data integrity and potentially exposes the entire evaluation system to unauthorized access and manipulation.
Mitigation strategies for CVE-2026-1478 should focus on implementing robust input validation and parameterized query execution throughout the application's codebase. The immediate solution involves replacing direct sql concatenation with proper parameterized queries or stored procedures that separate user input from sql command structure. Additionally, implementing network-level controls such as firewall rules that restrict external dns resolution and http requests from database servers can limit the attack surface. Regular security code reviews and automated static analysis should be implemented to identify similar vulnerabilities in other application components. Organizations should also consider implementing database activity monitoring and intrusion detection systems specifically configured to detect out-of-band sql injection attempts. The fix should align with security framework standards including owasp top ten and iso 27001 requirements for secure coding practices, ensuring that all user inputs are properly validated and sanitized before database processing occurs.
