CVSS v3.1
Official Description
Sun Java System Directory Proxy Server in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3, when a JDBC data source is used, does not properly handle (1) a long value in an ADD or (2) long string attributes, which allows remote attackers to cause a denial of service (JDBC backend outage) via crafted LDAP requests.
Technical Analysis
CVE-2009-0609 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
