Subject: SECURITY ADVISORY (BEA03-29.00)
Minor Subject: Remedy available to prevent deletion of subcontexts
Product(s) Affected: WebLogic Server and Express
Threat Level: Low
Recently a problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server and Express. Patches are available to correct this problem (see section II below). BEA treats such possibilities with the highest degree of urgency and does everything possible to ensure the security of all customer assets. As a result, we strongly suggest the following action:
I. Read the following advisory.
II. Apply the suggested action.
III. If you know of any additional users interested in future security advisories, please forward them the registration instructions below.
JNDI access is protected by the WebLogic Server via policies that are set in the console. We protect the JNDI tree with three permissions: "lookup", "modify" and "list". The ""modify" permission is supposed to protect against items in the JNDI tree being added, deleted or changed. Due to a coding mistake in WebLogic Server, the "modify" permission does not protect against the deletion of empty sub-contexts. That is, all users can delete empty sub-contexts.
The following versions of WebLogic Server and Express are affected by this vulnerability
- WebLogic Server and Express 7.0 and 220.127.116.11, on all platforms
II. SUGGESTED ACTION
Oracle strongly recommends the following course of actions:
- WebLogic Server and Express 7.0 and 18.104.22.168
- Upgrade to Service Pack 2
Oracle strongly suggests that customers apply the remedies recommended in all our security advisories. Oracle also urges customers to apply every Service/Maintenance Pack as they are released. Service/Maintenance Packs include a roll-up of all bug fixes for each version of the product, as well as each of the prior Service/Maintenance Packs. Service/Maintenance Packs and information about them can be found at:

We strongly encourage you to review this documentation to ensure your server deployment is securely configured.
As a policy, if there are any security-related issues with any Oracle product, Oracle will distribute an advisory and instructions with the appropriate course of action.
