CVE-2026-63165 in Agora Project
Summary
by MITRE • 10/13/2026
Omnispace Agora Project before 26.10.0 contains a SQL injection vulnerability in the calendar functionality that allows attackers to inject malicious SQL by manipulating the sortEvents parameter, which is concatenated into the ORDER BY clause without sanitization in app/ModCalendar/CtrlCalendar.php. Attackers can exploit this flaw using error-based techniques such as extractvalue payloads to extract database information, including version data, from the underlying system.

The Omnispace Agora Project prior to version 26.10.0 contains a critical SQL injection vulnerability within its calendar management subsystem, specifically located in the file app/ModCalendar/CtrlCalendar.php. This flaw arises from improper input validation and sanitization of user-supplied data passed through the sortEvents parameter. When processing requests for event sorting, the application directly concatenates this unsanitized input into an SQL ORDER BY clause without applying any filtering or escaping mechanisms. This architectural oversight allows remote attackers to inject arbitrary Structured Query Language code, fundamentally compromising the integrity and confidentiality of the underlying database system.
The technical nature of this vulnerability is classified as a classic injection flaw where user input is treated as executable code rather than data. By manipulating the sortEvents parameter, an attacker can alter the structure of the SQL query executed by the backend application server. The specific exploitation vector highlighted involves error-based extraction techniques using payloads such as extractvalue. This method leverages database errors to leak sensitive information that would otherwise be hidden from standard output. Through this mechanism, attackers can successfully retrieve detailed database metadata, including version numbers and potentially other schema details, which serve as critical intelligence for further targeted attacks against the infrastructure.
From an operational perspective, the impact of this vulnerability extends beyond simple data disclosure. While the immediate exploit described focuses on information gathering via error-based extraction, SQL injection vulnerabilities often provide a pathway to more severe consequences such as unauthorized data access, modification, or deletion depending on the database user privileges assigned to the application. The exposure of database versioning allows attackers to identify specific known exploits associated with that software release, facilitating rapid escalation of attacks. This compromises the confidentiality and integrity aspects of the CIA triad for any sensitive calendar data stored within the Omnispace Agora system.
This vulnerability aligns with Common Weakness Enumeration identifier CWE-89, which describes Improper Neutralization of Special Elements used in an SQL Command. In terms of offensive security frameworks, this exploitation technique corresponds to MITRE ATT&CK tactic T1059, specifically subtechnique T1059.004 for command and scripting interpretation via database commands, and aligns with the discovery phase under TA0007 as it enables reconnaissance through error-based data extraction. The lack of parameterized queries or strict input validation represents a fundamental deviation from secure coding standards recommended by OWASP for preventing SQL injection attacks in web applications.
To mitigate this vulnerability, immediate remediation is required by upgrading the Omnispace Agora Project to version 26.10.0 or later where these issues have been addressed. For systems that cannot be immediately upgraded, implementing strict input validation on the sortEvents parameter is essential. Developers should ensure that only predefined sorting options are accepted and reject any input containing SQL special characters such as single quotes, semicolons, or comment sequences. Additionally, employing prepared statements with parameterized queries for all database interactions involving user-supplied data will prevent the injection of malicious code into the ORDER BY clause. Enabling detailed logging and monitoring can also aid in detecting attempted exploitation activities based on unusual query patterns or error responses generated by the application server.
