Exploitation Summary

EIP tracks 1 public exploit for CVE-2007-4639. PoCs published by Joxean Koret.

AI-analyzed exploit summary This exploit demonstrates an uninitialized-pointer vulnerability in EnterpriseDB Advanced Server 8.2. By executing a specific SQL query with a crafted argument, an authenticated attacker can trigger a denial-of-service (DoS) condition, potentially leading to remote code execution.

Description

EnterpriseDB Advanced Server 8.2 does not properly handle certain debugging function calls that occur before a call to pldbg_create_listener, which allows remote authenticated users to cause a denial of service (daemon crash) and possibly execute arbitrary code via a SELECT statement that invokes a pldbg_ function, as demonstrated by (1) pldbg_get_stack and (2) pldbg_abort_target, which triggers use of an uninitialized pointer.
