CVE-2018-1282

Vulnerability

The vulnerability resides in the Apache Hive JDBC driver (hive-jdbc) versions 0.7.1 through 2.3.2 [1][3]. The driver's PreparedStatement implementation fails to properly escape or clean user-supplied arguments, allowing an attacker to inject arbitrary SQL by crafting specially constructed arguments [1][3].

Exploitation

An attacker can exploit this vulnerability by providing malicious input to a PreparedStatement parameter. No authentication is required if the JDBC interface is exposed; the attacker only needs network access to the Hive JDBC endpoint. The crafted arguments bypass the intended escaping mechanism, enabling SQL injection [1][3][4].

Impact

Successful exploitation allows an attacker to execute arbitrary SQL commands on the Hive server. This can lead to unauthorized data access, modification, or deletion, potentially compromising the entire Hive data warehouse [1][3]. The vulnerability is rated critical (CVSS 9.8) [3].

Mitigation

The vulnerability is fixed in Apache Hive version 2.3.3 [3][4]. Users should upgrade to 2.3.3 or later. If upgrading is not immediately possible, restrict network access to the Hive JDBC endpoint and monitor for suspicious queries [1][3].
