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 References SecurityFocus, http://www.securityfocus.com, has assigned a Bugtraq ID (BID) to this issue for inclusion in the SecurityFocus vulnerability database.The BIDs assigned is 29350 which can be found at http://www.securityfocus.com/bid/29350 Credit Symantec would like to thank Nicolas Pouvesle with Tenable Security for reporting this issue.
