IBM DB2 method privilege escalation
| db2-method-privilege-escalation (36108) |  High Risk |
Description:
IBM DB2 could allow a remote attacker to gain elevated privileges on the system, caused by the improper revoking of privileges on methods. A remote authenticated attacker could exploit this vulnerability to gain privileges and execute authority on methods until the cache is cleared or the database is deactivated.
