Content
VULNERABILITY DETAILS:
CVE ID: CVE-2012-0720 (PM52274)
DESCRIPTION: WebSphere Application Server Administration Console is vulnerable
to cross-site scripting, caused by improper validation of user-supplied input
by the Administrative Console. A remote attacker could exploit this
vulnerability using unspecified attack vectors to inject script in a victims
Web browser within the security context of the hosting Web site.
CVSS:
CVSS Base Score: 4.3
CVSS Temporal Score: Seehttp://xforce.iss.net/xforce/xfdb/74044 for the current
score
CVSS Environmental Score*: Undefined
CVSS String: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
AFFECTED PLATFORMS: The following IBM WebSphere Application Server for
distributed operating systems, IBM i operating systems, and z/OS operating
system Versions are affected:
Version 8
Version 7
Version 6.1
REMEDIATION: The recommended solution is to apply the Fix Pack or PTF for each
named product as soon as practical
Fix:
Apply a Fix Pack or PTF containing this APAR PM52274, as noted below:
For IBM WebSphere Application Server
For V8.0 through 8.0.0.2:
o Install Fix Pack 3 (8.0.0.3), or later.

enabled by default, SSLClientAuth required not affected
SSLv2 has not been disabled with SSLProtocolDisable SSLv2
SSLClientAuthRequire is not configured
