10/20/2005 - Adding notice to users of public posting of exploit code
|Exploit publicly available||Yes|
NOTE: Exploit code for the Linux, Win32, and Mac OS X platforms is publicly available. Customers who have not patched yet, should do so immediately.
The remote exploitation of a format string overflow vulnerability in the Java user-interface authentication service, bpjava-msvc, running on VERITAS NetBackup servers and agents, could potentially allow remote attackers to execute arbitrary code on a targeted system with elevated privileges.

Note: VERITAS NetBackup DataCenter and BusinesServer 4.5MP for Windows does NOT use the bpjava-msvc component.
TippingPoint, a division of 3Com, notified Symantec of a format string overflow vulnerability in VERITAS NetBackup that could potentially allow a remote attacker to execute arbitrary code. The vulnerability exists in the authentication service, bpjava-msvc daemon, in the Java user-interface. If a remote attacker were able to access the service and successfully exploit this vulnerability, they could potentially execute arbitrary code with the privileges of the bpjava-msvc daemon, normally root or SYSTEM, on the targeted system.
Symantec Engineers have verified this issue and made security updates available for the supported VERITAS NetBackup products. Symantec strongly recommends all customers immediately apply the latest updates for their supported product versions to protect against these types of threats.
The patches listed above for NetBackup DataCenter and NetBackup BusinessServer 4.5 and for NetBackup Enterprise Server and NetBackup Server 5.0, 5.1, and 6.0 are available from the following location:
NOTE: In a recommended installation, VERITAS NetBackup should be restricted to trusted access only. The VERITAS NetBackup Server or clients should never be visible external to the network which greatly reduces opportunities for unauthorized access.
Symantec Security Response has released IPS/IDS signatures to detect and prevent attempts to exploit this issue.
Symantec ManHunt 3.0 signatures are available for update from the Symantec Security Response Update Center at:
Symantec Network Security Appliance 7100 signatures are available for update from the Symantec Security Response Update Center at:
Symantec Gateway Security 3.0 signatures are available for update from the Symantec Security Response Update Center at:
Symantec Client Security 2.0 and 3.0 signatures are available for update via LiveUpdate and from the Security Response Update Center at:
Customers using Symantec Client Security 2.0 and 3.0 should have already uploaded this signature if they run LiveUpdate regularly. If not, Symantec recommends customers manually run Symantec LiveUpdate to ensure they have the most current protection.
As part of normal best practices, Symantec strongly recommends:
- Restricting access to administration or management systems to privileged users.
- Restricting remote access, if required, to trusted/authorized systems only.
- Running under the principle of least privilege where possible to limit the impact of exploit by threats such as this.
- Keeping all operating systems and applications updated with the latest vendor patches.
- Following a multi-layered approach to security. Run both firewall and antivirus applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.
- Deploying network 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
The Common Vulnerabilities and Exposures (CVE) initiative has assigned CVE Candidate CAN-2005-2715 to this issue.
This issue is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems.
