Oracle Database Local Untrusted Library Path Vulnerability
17 Jul. 2008
Summary
Oracle Database Server is "a family of database products that range from personal databases to enterprise solutions". Local exploitation of an untrusted library path vulnerability in Oracle Corp.'s Oracle Database product allows attackers to gain elevated privileges.
Vulnerable Systems:
* Oracle 11g R1 version 11.1.0.6.0 on 32-bit Linux platform
Immune Systems:
*
This vulnerability specifically exists in a set-uid root program distributed with Oracle Database for Linux and Unix platforms. By replacing a module owned by the oracle user, which is loaded by this program, an attacker can execute arbitrary code as root.
Analysis:
Exploitation allows the attacker to gain root privilege. In order to exploit the vulnerability, the attacker must have access to database owner account, typically "oracle", or be a member of oracle installation group, typically "oinstall".
Workaround:
In order to prevent exploitation, administrators can remove the set-uid bit from the vulnerable program. However, doing so could impair the functionality of the DBMS_SCHEDULER package.
