Symantec Backup Exec System Recovery Manager
Tenable Security reported a directory traversal vulnerability in Symantec Backup Exec System Recovery manager. Successfully exploitation could potentially allow an authorized network user to be able to read privileged system files and potentially gain unauthorized access on the targeted system.
Symantec has verified this issue and 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.
For additional information, see the tech note at: http://entsupport.symantec.com/docs/304224 .
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.
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.
Symantec would like to thank Nicolas Pouvesle with Tenable Security for reporting this issue.
