versions of Symantec Backup Exec System Recovery Manager. The update can be 
downloaded from https://fileconnect.symantec.com.

Mitigation
Symantec has released an IPS signature to detect and block attempts to exploit 
this vulnerability. The signature, HTTP Backup Exec Sys Recovery Dir Trav, is 
available in signatures dated 05/28/2008 and later.

Best Practices
As part of normal best practices, Symantec strongly recommends:

    * Restrict access to administration or management systems to privileged 
      users.
    * Restrict remote access, if required, to trusted/authorized systems only.
    * Run under the principle of least privilege where possible to limit the 
      impact of exploit by threats.
    * Keep all operating systems and applications updated with the latest 
      vendor patches.
    * Follow a multi-layered approach to security. Run both firewall and 
      anti-malware applications, at a minimum, 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 detection of attacks or malicious activity related to exploitation
      of latent vulnerabilities
