Vigil@nce: MySQL, altering tables

September 2008 by Vigil@nce

SYNTHESIS

A local attacker can use DATA DIRECTORY and INDEX DIRECTORY to alter database tables.

Gravity: 2/4

Consequences: data creation/edition

Provenance: user shell

Means of attack: no proof of concept, no attack

Ability of attacker: expert (4/4)

Confidence: multiples sources (3/5)

Diffusion of the vulnerable configuration: high (3/3)

Creation date: 16/09/2008

Identifier: VIGILANCE-VUL-8109

IMPACTED PRODUCTS

- MySQL [confidential versions]
- MySQL Community Server [confidential versions]
- MySQL Enterprise Server [confidential versions]

DESCRIPTION

The DATA DIRECTORY and INDEX DIRECTORY options indicates paths where data and index files of a table are located. An attacker can use them to access to tables with the same name. This vulnerability has the reference CVE-2008-2079 (VIGILANCE-VUL-7804 (https://vigilance.aql.fr/tree/1/7804), VIGILANCE-VUL-7803 (https://vigilance.aql.fr/tree/1/7803), VIGILANCE-VUL-7802 (https://vigilance.aql.fr/tree/1/7802)).

This vulnerability was corrected. However, patches were incorrect:

- the official patch can be bypassed using symbolic links (CVE-2008-4098)
- the Debian patch can be by passed by changing the path (CVE-2008-4097)

A local attacker can thus still use DATA DIRECTORY and INDEX DIRECTORY to alter database tables.

CHARACTERISTICS

Identifiers: 32167, CVE-2008-2079, CVE-2008-4097, CVE-2008-4098, VIGILANCE-VUL-8109
