CVE-2026-81675 in iSquad
Summary
by MITRE • 08/27/2026
The endpoint ‘/ws/apiprensa/getVideoUltimasSeccion’ contains an SQL injection vulnerability in the id_seccion parameter. The parameter is directly embedded in a complex SQL query that includes grouping and sorting operations. By injecting SQL syntax, an attacker can disrupt the query structure and cause database errors, exposing the internal logic of the queries. The complexity of the query increases the potential impact, as it could allow for broader manipulation of the content retrieval logic.

The vulnerability identified in the endpoint /ws/apiprensa/getVideoUltimasSeccion represents a classic SQL injection flaw rooted in improper input validation and unsafe database query construction. The specific weakness lies within the id_seccion parameter, which is directly concatenated into a complex SQL statement without adequate sanitization or the use of prepared statements with parameterized queries. This architectural oversight allows an attacker to inject arbitrary SQL syntax that alters the intended logic of the database operation. Because the underlying query involves grouping and sorting operations, the injection point offers significant leverage for manipulating how data is aggregated and presented, rather than merely extracting static records from a single table.
From a technical perspective, this vulnerability aligns with CWE-89, which classifies SQL Injection as a critical category of input validation failures where untrusted data is sent to an interpreter as part of a command or query. The complexity of the target query amplifies the risk because it likely utilizes functions such as GROUP BY and ORDER BY that are sensitive to structural changes in the SQL string. An attacker can exploit this by injecting payloads designed to break out of the current context, potentially using techniques like UNION-based injection to append additional SELECT statements or error-based injection to trigger database errors that reveal schema details. The presence of grouping operations means that an injected clause could fundamentally change which records are selected and how they are categorized, leading to severe data integrity issues.
The operational impact of this vulnerability extends beyond simple data exfiltration. By disrupting the query structure, an attacker can cause denial-of-service conditions through resource-intensive queries or logical errors that crash the application layer. More critically, the exposure of internal database logic allows for reconnaissance activities where attackers map out table structures and column names by observing error messages returned to the client. This information is often a precursor to more destructive attacks, such as modifying administrative credentials, deleting critical records, or extracting sensitive user data stored in related tables that are joined within the complex query structure. The ability to manipulate content retrieval logic also poses a risk of integrity compromise, where an attacker could alter what videos or news items are displayed to end-users by injecting conditions that filter results differently than intended.
This vulnerability is closely associated with MITRE ATT&CK technique T1059, specifically Command and Scripting Interpreter sub-techniques if the database engine allows for OS-level command execution via functions like xp_cmdshell in Microsoft SQL Server or similar capabilities in other databases. Even without direct system access, this flaw facilitates data exfiltration as described by MITRE ATT&CK technique T1005. The lack of input validation on a web service endpoint makes it particularly attractive to automated scanning tools and script-kiddies who frequently target common API endpoints for SQL injection opportunities.
To mitigate this vulnerability, immediate remediation should focus on implementing parameterized queries or prepared statements for all database interactions involving the id_seccion parameter. This ensures that user input is treated strictly as data rather than executable code, neutralizing any injected syntax. Additionally, applying strict input validation by enforcing expected data types and formats can provide a secondary layer of defense; since section IDs are typically numeric integers, rejecting non-numeric inputs before they reach the database layer would prevent most injection attempts. Implementing a Web Application Firewall with rules specifically tuned to detect SQL injection patterns in API parameters can also help block malicious traffic while longer-term code fixes are deployed. Regular security testing and static application security testing should be integrated into the development lifecycle to catch such flaws early, ensuring that complex queries remain secure against evolving attack vectors.
