SQL Injection Through Unquoted Identifiers in DBIx::QuickORM

DBIx::QuickORM versions before 0.000026 for Perl allow SQL injection via unquoted SQL identifiers. The default SQL builder, a SQL::Abstract subclass, sets bindtype in its constructor but never quote_char, so SQL::Abstract emits identifiers verbatim. Caller-supplied identifiers (order_by, where-clause column keys, field and returning lists, upsert columns, and join aliases) reach the SQL string raw, while values are placeholder-bound and unaffected. A caller that forwards untrusted input to an affected identifier position, such as a user-controlled order_by value, enables SQL injection: the row order can be made to depend on a sub-select over columns the query never selected, and the where and update identifier positions permit further data disclosure and tampering.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

DBIx::QuickORM versions before 0.000026 contain a critical SQL injection vulnerability stemming from improper identifier quoting in the default SQL builder. The vulnerability allows attackers to inject arbitrary SQL code through caller-supplied identifiers such as order_by clauses, where-clause column keys, field lists, returning lists, upsert columns, and join aliases. While the library properly uses parameterized queries for values, it fails to quote SQL identifiers, causing them to be emitted verbatim into the SQL string. This affects any Perl application using vulnerable versions of DBIx::QuickORM that processes untrusted user input as part of query construction, potentially allowing complete database compromise through data exfiltration, modification, or deletion.

Casky's 322 mapped security skills leverage Claude's extended reasoning to detect the attack patterns associated with this vulnerability across the MITRE ATT&CK framework. The platform's analysis focuses on TA0001 (Reconnaissance) and TA0043 (Reconnaissance via resource scanning), identifying how attackers probe for parameter injection points in database query construction. Practitioners using Casky would observe findings highlighting anomalous identifier patterns in database logs, suspicious column name references that deviate from application schema, and unquoted SQL constructs appearing in query execution traces. The extended reasoning engine correlates identifier injection attempts with CWE-89 (SQL Injection) patterns, flagging instances where user-controlled data flows directly into identifier positions rather than value parameters—a critical distinction that distinguishes this vulnerability from standard parameterized query bypasses.
