CVE-2026-1479 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 parameters 'Id_usuario' and 'Id_evaluacion’ in ‘/evaluacion_hca_ver_auto.asp', 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-2026-1479 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 /evaluacion_hca_ver_auto.asp script where the parameters Id_usuario and Id_evaluacion are susceptible to malicious input manipulation. The vulnerability classifies under CWE-643 as it involves improper neutralization of data within a sql query context, specifically targeting the application's database interaction mechanisms. The out-of-band nature of this injection means that attackers can extract data through external channels rather than relying on direct response mechanisms, making detection more challenging and the attack more sophisticated.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious input for the Id_usuario and Id_evaluacion parameters that manipulate the underlying sql query structure. Through careful manipulation of these parameters, an attacker can trigger database queries that return sensitive information through external communication channels such as dns requests or http calls to attacker-controlled servers. This approach bypasses traditional sql injection defenses that rely on detecting and blocking direct query responses, as the data exfiltration occurs through separate communication pathways. The vulnerability essentially allows for blind sql injection techniques where the attacker can extract information through secondary channels, making it particularly dangerous for applications handling confidential data.
The operational impact of CVE-2026-1479 extends beyond simple data theft, as it compromises the fundamental confidentiality of stored information within the application's database. Attackers can potentially extract user credentials, performance evaluation records, personal information, and other sensitive data without leaving obvious traces in traditional application logs. The vulnerability affects the integrity of the entire evaluation system and could lead to unauthorized access to performance data that may include personal assessments, ratings, and other confidential information. This type of vulnerability directly violates security principles outlined in the att&ck framework under technique T1071.004 for application layer protocol tunneling, where attackers establish covert communication channels for data exfiltration.
Mitigation strategies for this vulnerability should prioritize immediate patching of the affected application to properly sanitize all input parameters before database interaction. The solution involves implementing strict input validation and parameterized queries to prevent malicious sql code execution. Security measures should include input filtering that rejects or escapes special sql characters, implementing proper access controls, and monitoring for unusual external communication patterns that may indicate data exfiltration attempts. Organizations should also consider network-level monitoring to detect dns tunneling or other external channel communications that could indicate exploitation attempts. Additionally, implementing web application firewalls and database activity monitoring systems can provide additional layers of protection against similar out-of-band injection attacks. The remediation process should follow industry standards such as owasp top ten recommendations for sql injection prevention and nist cybersecurity framework guidelines for vulnerability management and incident response.
