Technical details

A SQL injection vulnerability exists in the phpBB profile field migration component (CWE-89). The root cause is the improper neutralization of user-supplied profile field data during the migration process. An attacker with low-level privileges (PR:L) could exploit this over the network, though it requires high complexity (AC:H) and potentially user interaction (UI:R). Successful exploitation allows the execution of arbitrary SQL queries, potentially leading to unauthorized data access or modification. The vulnerability specifically impacts forums updated from versions prior to 3.3.8 that have not yet reached version 3.3.11.
