## Content

**VULNERABILITY DETAILS: **

**CVE ID: ****_CVE-2013-0597 (PM85834 and PM87131) _****
****
DESCRIPTION: **WebSphere Application Server using OAuth could allow a remote attacker to obtain someone else’s credentials. A remote attacker could exploit this vulnerability to steal the victim’s cookie-based authentication credentials. **

CVSS:** _

CVSS Base Score: 3.5
CVSS Temporal Score: See _[_https://exchange.xforce.ibmcloud.com/vulnerabilities/83609_]() _for the current score
CVSS Environmental Score*: Undefined
CVSS String: (AV:N/AC:M/Au:S/C:N/I:P/A:N)_**

AFFECTED VERSIONS: **

The problem affects the following IBM WebSphere Application Server Versions:

* Version 8.5.0.0 through 8.5.0.2
* Version 8.0.0.0 through 8.0.0.6
* Version 7.0.0.25 through 7.0.0.27 – OAuth functionality was added in Version 7 Fix Pack 25 so this does not exist in fix packs prior to 7.0.0.25 or earlier early versions such as 6.0 or 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 PM85834, as noted below: **
