Summary
Omnispace Agora Project contains a SQL injection vulnerability in its calendar functionality because the sortEvents parameter is incorporated into an ORDER BY clause without adequate sanitization. An attacker who can reach the affected calendar functionality may manipulate this parameter to cause database errors and potentially extract information from the underlying database.

Affected context
The vulnerability occurs in the calendar functionality of Omnispace Agora Project before version 26.10.0, specifically in app/ModCalendar/CtrlCalendar.php. It becomes risky when externally influenced sortEvents input reaches SQL query construction without parameter-aware handling or strict allowlisting of permitted sort values.

It becomes risky when externally influenced sortEvents input reaches SQL query construction without parameter-aware handling or strict allowlisting of permitted sort values.
Exploit preconditions
- Attack surface: Calendar functionality that accepts the
sortEventsparameter - Required access: Access sufficient to submit requests to the affected calendar endpoint; authentication requirements depend on deployment configuration
- Trigger point: Processing the parameter while constructing the SQL
ORDER BYclause - Why exploitation is possible: User-controlled input is concatenated into a SQL statement without sufficient validation or constrained query construction

Why this happens
The underlying bug is improper neutralization of externally controlled input used in a SQL statement, which maps to CWE-89: Improper Neutralization of Special Elements used in an SQL Command (SQL Injection). The application treats a sorting value as trusted SQL syntax and concatenates it into an ORDER BY clause instead of restricting it to known-safe columns and directions. Because sorting identifiers generally cannot be safely handled with ordinary value placeholders, they require explicit allowlisting and separate query construction logic.

Potential impact
- Database metadata or other accessible information may be disclosed
- Database version details could be extracted through error-based behavior
- Query errors may expose implementation or schema information
- Application data could potentially be modified or deleted if the database account permits it
- The application or connected services could be affected through database compromise
- Database metadata or other accessible information may be disclosed
- Database version details could be extracted through error-based behavior
- Query errors may expose implementation or schema information
- Application data could potentially be modified or deleted if the database account permits it
- The application or connected services could be affected through database compromise
General mitigation guidance
Mitigation typically focuses on preventing user-controlled values from becoming SQL syntax.
Common defensive patterns include:
- Map client-facing sort options to a fixed allowlist of known database columns
- Accept only explicitly supported sort directions and reject unexpected values
- Keep sorting identifiers separate from ordinary query values and construct them through trusted mappings
- Apply least-privilege permissions to the application database account
- Avoid returning detailed database errors to clients
- Centralize query-building controls and reduce trust in request parameters through schema validation
- Use secure-by-default query helpers and review dynamically assembled SQL paths

How teams detect issues like this
Organizations commonly detect SQL injection risks through:
- Static analysis rules for string concatenation or interpolation in SQL construction
- Code review checks for request parameters used in
ORDER BY,GROUP BY, filtering, or projection clauses - Dynamic testing that supplies unexpected sort names, directions, and malformed values to observable query paths
- Database and application logging policies that identify repeated query errors or unusual metadata access
- Policy enforcement requiring allowlisted query fragments and least-privilege database accounts
Automated security review tools may help identify unsafe query construction, but findings should be validated against the actual data-access layer.
