Security Advisory

1) Cross-site scripting

Description

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

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

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.

2) Permissions, Privileges, and Access Controls

Description

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists due to insecure directory permissions set on a JCF created directory. A local attacker with the ability to access an affected directory can create a hard link to an arbitrary location, convince another user that has administrative privileges to perform an install or update the Cisco Jabber for Mac client to perform such actions, allowing files to be created in an arbitrary location on the disk or an arbitrary file to be corrupted when it is appended to or overwritten.

Remediation

Install updates from vendor's website.
