Tamper Protection Bypass

Description:

|

The Symantec SONAR component, prior to 12.0.2, may be susceptible to a tamper protection bypass vulnerability which could potentially allow an attacker to circumvent the existing tamper protection in use on the resident system.

MITIGATION

This issue has been validated by Symantec engineers. An update for Symantec SONAR, version 12.0.2 has been released to address this issue. Note that this release has already been pushed out automatically via Symantec LiveUpdate; no additional action is required by customers. At this time, Symantec is not aware of any exploitations or adverse customer impact from this issue.

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.
