Date: Wed, 4 Apr 2018 14:58:43 -0700 From: Daniel Dai <daijy@...che.org> To: user@...e.apache.org, dev@...e.apache.org, announce@...che.org, security <security@...e.apache.org>, oss-security@...ts.openwall.com, Danny Grander <danny@...k.io> Subject: [SECURITY] CVE-2018-1315 'COPY FROM FTP' statement in HPL/SQL can write to arbitrary location if the FTP server is compromised CVE-2018-1315: 'COPY FROM FTP' statement in HPL/SQL can write to arbitrary location if the FTP server is compromised Severity: Moderate Vendor: The Apache Software Foundation Versions Affected: Hive 2.1.0 to 2.3.2 Description: When 'COPY FROM FTP' statement is run using HPL/SQL extension to Hive, a compromised/malicious FTP server can cause the file to be written to an arbitrary location on the cluster where the command is run from. This is because FTP client code in HPL/SQL does not verify the destination location of the downloaded file. This does not affect hive cli user and hiveserver2 user as hplsql is a separate command line script and needs to be invoked differently. Mitigation: User who use HPL/SQL with Hive 2.1.0 through 2.3.2 should upgrade to 2.3.3 which removes support for "COPY FROM FTP". Alternatively, the usage of HPL/SQL can be disabled through other means. Credit: This issue was discovered by Danny Grander of Snyk
