CA BrightStor 'AddColumn()' ListCtrl.ocx ActiveX Control Buffer Overflow Vulnerability

Risk

High

Date Discovered

March 16, 2008

Description

The Unicenter DSM r11 List Control ATX ActiveX control, included with CA BrightStor ARCserve Backup, is prone to a buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer. An attacker can exploit this issue to execute arbitrary code in the context of an application running the control (typically Internet Explorer). Failed attacks will cause denial-of-service conditions.

Recommendations

Run all software as a nonprivileged user with minimal access rights.

To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not follow links provided by unknown or untrusted sources.

To reduce the likelihood of successful attacks, never follow links provided by unknown or untrusted individuals.

Set web browser security to disable the execution of script code or active content.

Since a successful exploit of these issues allows malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.

Implement multiple redundant layers of security.

Since these issues may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
