Description Josh Bressers 2006-02-27 15:15:09 EST
Mysql log file obfuscation


The following text is from tgl:

Yeah, problem confirmed locally: the query log message is truncated,

060227 11:15:47       6 Connect     root@localhost on test
6 Query       /* x */ select 2+2
6 Quit
060227 11:16:24       7 Connect     root@localhost on test
7 Query       /*
7 Quit

The report is perhaps deliberately obscure: you can *not* exploit this
through mysql_query() because it expects a null-terminated string
anyway.  But you can exploit it through mysql_real_query() which takes
a pointer and count.

I'd class the severity as pretty low, since all it allows is hiding
some traces of an attack after the attacker has already broken into
the database.  But since MySQL make a point of how mysql_real_query()
supports embedded nulls in the query string, it's certainly a bug.

This issue also affects RHEL3
This issue also affects RHEL2.1

Testcase from tgl

    I've attached a test case.	Start the server with query logging enabled
    (easiest way is to modify the init script to add "--log" to the
    mysqld_safe command line), run program, look at log file.
