Subject: Security Advisory (BEA08-189.00)
From: Oracle Corporation
Minor Subject: Cross-site scripting (XSS) vulnerabilities in Web applications using either WebLogic Workshop NetUI or Apache Beehive NetUI page flows
Product(s) Affected: WebLogic Workshop, BEA Workshop for WebLogic
Threat level: High
Although this requires careful orchestration, this method of attack has been publicly documented.
An attacker may be able to gain the enhanced privileges of clients of a particular web site.
A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Workshop and BEA Workshop for WebLogic. Patches and upgrades are available to correct this problem (see Section II). Oracle treats potential security problems with a high degree of urgency and endeavors to take appropriate steps to help ensure the security of our customers� systems. As a result, Oracle strongly suggests the following actions:
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 included in this advisory.
Background: Cross-Site Scripting (XSS) vulnerabilities are well documented in the industry. An XSS vulnerability requires three parties:
- A susceptible Web site.
- A valid user of the Web site.
- An attacker.
The attacker tricks the user (usually via misleading links on web pages or emails) to exploit the XSS vulnerability in the Web site. This allows the attacker to run arbitrary client-side (i.e. browser) scripts that execute as the identity of the valid user. Typically this is used to steal session cookies thereby allowing the attacker to impersonate the valid user. XSS vulnerabilities can arise due to bugs in the Web server or in applications running on it.
Applications implemented using the WebLogic Workshop or Apache Beehive NetUI framework with page flows may be vulnerable to XSS via a framework defined request parameter.
This advisory resolves this issue within the NetUI framework by sanitizing request parameters.
