CVE-2023-2696Network attack vector

SQL injection via columns data parameter

Published May 14, 2023 · Updated Aug 2, 2024

SQL injection in SourceCodester Online Exam System 1.0 allows remote attackers to alter database queries via the columns[1][data] POST parameter. The /matkul/data POST Parameter Handler incorporates the attacker-controlled data value into SQL without effective parameterization or neutralization. Remote reachability is sufficient and the resulting query manipulation can read or modify database-backed exam information; the published record does not establish a more specific privilege gate.
