-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Remote Buffer overflow in WebSphere Application Server Administrative Console AppSecInc Team SHATTER Security Advisory WEBSP05-V0098 http://www.appsecinc.com/resources/alerts/general/WEBSPHERE-001.html June 07, 2005 Risk level: HIGH Credits: This vulnerability was discovered and researched by Esteban Martínez Fayó of Argeniss for Application Security Inc. Affected Versions: IBM WebSphere Application Server 5.0 Background: The Administrative Console is a web-based tool used to manage the IBM WebSphere Application Server administrative server. The Administrative Console supports a full range of product administrative activities. Details: There is a Unicode buffer overflow in the WebSphere Application Server Administrative Console. The security vulnerability exists in the authentication mechanism. The authentication process takes place only when the 'global security option' is enabled in the server. The vulnerability can not be exploited if the security option is disabled. The default TCP ports where this vulnerability can be exploited include 9080 (HTTP), 9090 (HTTP) and 9043 (HTTPS). Impact: Unauthenticated attackers may execute arbitrary code in the context of the server process. Workaround: There is no workaround. The attack surface can be reduced by denying access to untrusted users on TCP ports 9080, 9090 and 9043. Vendor Status: Vendor was contacted and a patch was released. Fix: Apply the WebSphere Application Server 5.0.2 Cumulative Fix 11. The patch can be found here: http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg24009775 Links: Application Security, Inc advisory: http://www.appsecinc.com/resources/alerts/general/WEBSPHERE-001.html -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) iD8DBQFCpfX7/0w1dSVRt4URAsACAJoDG9TGi30QNOUFYv2VAdg9GaoVrQCgwBPd e03smGG+fj/kGkJ2Ns1d6EE= =C3Fq -----END PGP SIGNATURE-----
