Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU15287

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-1794

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data within OAuth ear. The vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

For V9.0.0.0 through 9.0.0.9:
· Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PH01753
--OR--
· Apply Fix Pack 9.0.0.10 or later (targeted availability 4Q 2018).

For V8.5.0.0 through 8.5.5.14:
· Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PH01753
--OR--
· Apply Fix Pack 8.5.5.15 or later (targeted availability 1Q 2019).

For V8.0.0.0 through 8.0.0.15:
· Upgrade to a minimal fix pack levels as required by interim fix and then apply Interim Fix PH01753

For V7.0.0.0 through 7.0.0.45:
· Upgrade to a minimal fix pack levels as required by interim fix and then apply Interim Fix PH01753
