Unauthorized Access

Description:

|

Symantec Industrial Control System Protection (ICSP), versions 6.x.x, may be susceptible to an unauthorized access issue that could potentially allow a threat actor to create or modify application user accounts without proper authentication.

MITIGATION

An update of the Industrial Control System Protection (ICSP), version 6.1.1.123, has been released which addresses this issue. The latest Industrial Control System Protection (ICSP) releases and patches are available to customers through normal support channels or via auto-update with an internet connection. Currently, there is no evidence of any attempts at this exploit in the wild.

Symantec recommends the following measures to reduce risk of attack:

• Restrict access to administrative or management systems to authorized privileged users.
• Restrict remote access to trusted/authorized systems only.
• Run under the principle of least privilege, where possible, to limit the impact of potential exploit.
• Keep all operating systems and applications current with vendor patches.
• Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications to provide multiple points of detection and protection for both inbound and outbound threats.
• Deploy network and host-based intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.
