Summary
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the PDO Firebird driver improperly handles NUL bytes when preparing SQL queries. During token-by-token query construction, a string token containing a NUL byte is copied via strncat(), which stops at the NUL byte, dropping the closing quote and causing subsequent SQL tokens to be interpreted as part of the string.
Risk Assessment
An attacker can exploit this vulnerability for SQL injection when attacker-controlled values are quoted via PDO::quote() and embedded in SQL statements, potentially leading to unauthorized data access or modification.
Recommendation
Immediately upgrade PHP to version 8.2.31, 8.3.31, 8.4.21, or 8.5.6 depending on the branch used. If an upgrade is not possible, avoid using PDO::quote() with data containing NUL bytes in Firebird database queries.
