ProductVersionSolution(s)
Symantec Backup Exec System Recovery Manager7.07.0.3

Details
A flaw exists in the FileUpload Class running on the Symantec LiveState Apache Tomcat server. An unauthorized file can be uploaded to the server through a malicious HTTP Post and placed anywhere on the server. Remote code execution with System level access is possible.

Symantec Response
Symantec has released an update for all affected versions of Symantec Backup Exec System Recovery Manager. The update can be downloaded from https://fileconnect.symantec.com. The update should be installed over your current version of Backup Exec System Recovery Manager. This will create new Easy Installer packages for 7.03. Push out the new Backup Exec System Recovery 7.03/Management Control package to all machines. (This can be done either through email, SMS, Logon Script, or downloaded from each machine). The machine must be rebooted for the update to be available.

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
