PR07-10: Frame Injection on Sun Java System Identity Manager 6.0/7.x "helpUrl" parameter

Date Found: 11th June 2007

Vendor Contacted: 18th June 2007

Severity: Medium

BID: 27214

Description:

Sun Java System Identity Manager is vulnerable to frame injection within the "helpUrl" parameter processed by the "/idm/help/index.jsp" server-side script.

Consequences:

Attackers may inject frames that embed third-party sites, which can help launching phishing attacks by injecting a frame that points to a "spoof" login page.

Additionally, this frame injection issue can result in non-persistent defacement of the target site.

Proof of concept (PoC):

The provided PoC URLs embed a third-party site (www.procheckup.com in this case):

https://target.tld/idm/help/index.jsp?helpUrl=//www.procheckup.com
https://target.tld/idm/help/index.jsp?helpUrl=http://www.procheckup.com
