Solution 253287 : Security Vulnerability in the VERITAS (Symantec)
NetBackup Network Daemon may Allow Escalation of Privileges
Bug ID: 6803212, 6803215, 6797673, 6797674
Product
Veritas NetBackup 6.0
Veritas NetBackup 6.5
Date of Resolved Release: 16-Apr-2009
SA Document Body
Security Vulnerability in the VERITAS (Symantec) NetBackup network daemon
may allow escalation of privileges:
1. Impact
A Security Vulnerability in the VERITAS (Symantec) NetBackup network
daemon may allow an unprivileged local user to leverage the Veritas
network daemon (vnetd) to gain elevated privileges on the system.
This issue is referenced in Symantec Security Advisory SYM09-002 at:
* http://seer.entsupport.symantec.com/docs/317828.htm
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* VERITAS (Symantec) NetBackup 6.0 GA version without patch
136859-01
* VERITAS (Symantec) NetBackup 6.0 MP4 CD version without patch
136860-01
* VERITAS (Symantec) NetBackup 6.5 without patch 136863-01
x86 Platform
* VERITAS (Symantec) NetBackup 6.5 without patch 136864-01
Note 1: NetBackup 5.x and earlier versions are no longer supported and
will require an upgrade to a later supported version with the
appropriate patches to resolve this issue.
Note 2: NetBackup 6.0 and earlier versions are not shipped for the
x86 Platform.
Note 3: To determine if a system is running the 6.0 GA version or the
6.0 MP4 CD version, execute the following command:
$ pkgparam VRTSnetbp VERSION
VERSION=6.0,REV=2005.09.07.19.13
The 6.0 GA version responds with VERSION=6.0,REV=2005.09.07.19.13
The 6.0 MP4 CD version responds with VERSION=6.0,REV=2006.11.09.18.12
3. Symptoms
There are no predictable symptoms to indicate that the described issue
has been exploited to gain elevated privileges.
4. Workaround
Sites unable to update immediately to the recommended solution should
restrict inbound access to the vnetd listening port (TCP/13724) on all
systems. This may be done by using firewall applications on the
affected systems. Please refer to the firewall documentation on how to
setup the access authorizations. Normal operations should restrict
client to client communications and allow master server to media
server, media server to media server, and master/media server to
client communications only.
As part of normal best practices, Symantec strongly recommends the
following:
* Restrict access to administration or management systems to
privileged users.
* Restrict remote access, if it is required, to trusted/authorized
systems only.
* Run under the principle of least privilege where possible to limit
the impact of potential exploits.
* Keep all operating systems and applications updated with the
latest vendor patches.
* Follow 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.
* Deploy 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.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* VERITAS (Symantec) NetBackup 6.0 GA version with patch
136859-01 or later
* VERITAS (Symantec) NetBackup 6.0 MP4 CD version with patch
136860-01 or later
* VERITAS (Symantec) NetBackup 6.5 with patch 136863-01 or later
x86 Platform
* VERITAS (Symantec) NetBackup 6.5 with patch 136864-01 or later
Notes:
Patches 136859-01 and 136860-01 have identical binaries, with
the only difference being the version of VRTSnetbp being patched. Only
one of the patches will be applied to a NetBackup system based on the
following:
Patch 136859-01 is applicable to VERITAS NetBackup 6.0 Product for
GA, with version string VERSION=6.0,REV=2005.09.07.19.13.
Patch 136860-01 is applicable to VERITAS NetBackup 6.0 MP4 CD with
version string VERSION=6.0,REV=2006.11.09.18.12.
