CVE-2026-110733
Description
A flaw was found in the Apache SIS SQL storage module. When sorting a stream of features, the application appends sort clauses to database queries after the ORDER BY statement without properly quoting identifier characters. An attacker capable of supplying a crafted sort clause could exploit this issue to execute arbitrary Structured Query Language (SQL) commands. This could lead to unauthorized data disclosure, modification, or unintended backend database operations.
Statement
This vulnerability is rated as Important because successful exploitation allows remote unauthenticated attackers to execute unauthorized database queries, potentially compromising backend database confidentiality and integrity. The risk is constrained to applications specifically integrating the Apache SIS SQL storage module and exposing feature sorting operations directly to untrusted input. Other components and modules within Apache SIS remain unaffected by this issue.
Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability
Technical Impact: Execute Unauthorized Code or Commands
Adversaries could execute system commands, typically by changing the SQL statement to redirect output to a file that can then be executed.
Confidentiality
Technical Impact: Read Application Data
Since SQL databases generally hold sensitive data, loss of confidentiality is a frequent problem with SQL injection vulnerabilities.
Authentication
Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism
If poor SQL commands are used to check user names and passwords or perform other kinds of authentication, it may be possible to connect to the product as another user with no previous knowledge of the password.
Access Control
Technical Impact: Bypass Protection Mechanism
If authorization information is held in a SQL database, it may be possible to change this information through the successful exploitation of a SQL injection vulnerability.
Integrity
Technical Impact: Modify Application Data
Just as it may be possible to read sensitive information, it is also possible to modify or even delete this information with a SQL injection attack.
