Vulnerability Information

Severity: Critical
Vulnerability Published: 2011-07-26
Patch Published: 2011-08-04
CVE [?]: CVE-2011-3011
CPE [?]: N/A

Synopsis

The remote web server hosts a Java servlet that is affected by an information disclosure vulnerability.

Description

The installed version of ARCserve D2D, a disk-based backup product from Computer Associates, allows an unauthenticated, remote attacker to discover the username and password used by the affected application. This can be accomplished by sending a specially crafted POST request to the 'homepageServlet' servlet that contains the getLocalHost message as well as the name of the Google Web Toolkit Procedure Call (GWT RPC) descriptor.

Note that these are credentials for the Windows user with Administrator privileges supplied during the ARCserve install process.

Note also that an attacker reportedly can use these credentials to gain access to the application and run arbitrary commands with the associated privileges on the affected host by, for example, configuring a command to run before a backup is started and then starting a backup.

Solution

Apply the RO33517 fix.
