Directory traversal

Description:

|

The Symantec Management Console can be susceptible to a directory traversal exploit, which is a type of attack that can occur when there is insufficient security validation / sanitization of user-supplied input file names, such that characters representing “traverse to parent directory” are passed through to the file APIs. The goal of this attack is to use an affected application to gain unauthorized access to the file system.

MITIGATION

This issue was validated by the product team engineers. A Symantec Management Console update, version ITMS 8.1 RU4 as well as patches ITMS 8.0 POST HF6 & ITMS 7.6 POST HF7, have been released which address the aforementioned issue. Note that the latest Symantec Management Console release and patches are available to customers through normal support channels. At this time, Symantec is not aware of any exploitations or adverse customer impact from this issue.

BEST PRACTICES

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 to 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.
