Security Bulletin

Summary

These vulnerabilities in the WebSphere eXtreme Scale monitoring console may 
allow an attacker to gain access to the monitoring console, getting read/only
access to statistics data on grid usage.

Vulnerability Details

CVEID: CVE-2015-2025

DESCRIPTION: IBM WebSphere Extreme Scale could allow a remote attacker to 
obtain sensitive information, caused by the failure to set the secure flag for
the session cookie in SSL mode. By intercepting its transmission within an 
HTTP session, an attacker could exploit this vulnerability to capture the 
cookie and obtain sensitive information.

CVSS Base Score: 3.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104053 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:S/C:P/I:N/A:N)

CVEID:CVE-2015-2026

DESCRIPTION: IBM WebSphere Extreme Scale is vulnerable to cross-site request 
forgery, caused by improper validation of user-supplied input. By persuading 
an authenticated user to visit a malicious Web site, a remote attacker could 
send a malformed HTTP. An attacker could exploit this vulnerability to perform
cross-site scripting attacks, Web cache poisoning, and other malicious 
activities.

CVSS Base Score: 3.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104054 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)

CVEID: CVE-2015-2027

DESCRIPTION: IBM WebSphere Extreme Scale could allow a local user to bypass 
security on another user's session due to it improperly logging out the 
previous user.

CVSS Base Score: 3.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104056 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)

CVEID: CVE-2015-2028

DESCRIPTION: IBM WebSphere Extreme Scale is vulnerable to a HTTP response 
splitting attack. A remote unauthenticated attacker could specify a specially
crafted URL to inject a malicious response to future requests.

CVSS Base Score: 3.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104057 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)

CVEID: CVE-2015-2029

DESCRIPTION: IBM WebSphere Extreme Scale could allow a remote attacker to 
hijack a user's session, caused by the failure to invalidate an existing 
session identifier. An attacker could exploit this vulnerability to gain 
access to another user's session.

CVSS Base Score: 3.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104058 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)

CVEID: CVE-2015-2030

DESCRIPTION: IBM WebSphere Extreme Scale uses an inadequate account lockout 
setting that could allow a remote attacker to brute force account credentials.

CVSS Base Score: 5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104070 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-2031

DESCRIPTION: IBM WebSphere Extreme Scale is vulnerable to cross-site 
scripting, caused by improper validation of user-supplied input. A remote 
attacker could exploit this vulnerability using a specially crafted URL to 
execute script in a victim's Web browser within the security context of the 
hosting Web site, once the URL is clicked. An attacker could use this 
vulnerability to steal the victim's cookie-based authentication credentials.

CVSS Base Score: 3.5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/104071 for the 
current score
