Text of original posting to Sun: >>Originator: EDS Information Assurance Group - Jim Hardisty, Mark Brewis >>Date of Contact: 22nd April 2003 >>Issue:During a recent Penetration Test, a member of the team, Jim Hardisty, identified an issue with an installation of >>iPlanet Administration Express. It is possible to escape the log viewer under iPlanet Administration Express, and >>since the application runs with root privilege, it is possible to access any file on the host server, including >>security critical files. >>Version: iPlanet Administration Server 5.1 >>The following URL will return the last 5000 accesses to passwd: >>http://192.168.192.168:5000/admin-serv/tasks/configuration/ViewLog?file=pa sswd&num=5000 &str=&directories=admin-serv%2Flogs%2f..%2f..%2f..%2f..%2f..%2f..%2fetc&id=a dmin-serv >>Once an escape has been made, the drop-down menu details all files under the called directory, e.g., /etc will lists >>shadow, hosts, hosts.allow, hosts.deny etc. >>We have identified users: >> 1) Failing to recognise the nature of the application, seeing it only as a web configuration app, and not >> appreciating that it runs setuid 0. As a result, they have been cavalier with password security, applying >> poor password controls, and have not applied ACLs to prevent unlimited internal access to the application. >> 2) Failing to apply a password to the application. During install, there must be a forced set password, and >> end-user must understand that this is a root level password they are setting. >> 3) Exposing the application to the Internet. >>Whether there are other escape sequences that will work is unknown. >>__________________ >>We will abide by the RFP Disclosure Guidelines v2.0 - www.wiretrip.net/rfp/policy.html. >>Should credit be forthcoming coming, please acknowledge Jim Hardisty as the discoverer, me as second string. >>Mark Brewis >>Security Consultant >>Information Assurance Group >>EDS SOLUTION ========= Sun have now informed me that the issue was addressed in: SunOne DS5.2 and in iDS5.1 SP2 Hotfix2 Sun(tm) ONE Directory Server 5.2 Release Notes Version 5.2 http://docs.sun.com/source/816-6703-10/index.html iPlanet Directory Server 5.1 Service Pack 2 Release Notes Updated June 11, 2003 http://docs.sun.com/db/doc/816-6403-10 I am unable to find a reference for Hotfix 2, so if anyone can supply one I'd be grateful, or if anyone can find a reference to this issue in either of the above, I'd be even more grateful!
