VERITAS NetBackup Enterprise Server delivers mainframe-class data
protection for the largest UNIX, Windows, Linux, and NetWare enterprise
environments, especially for corporate data centers.
VERITAS NetBackup Server software is cost-effective heterogeneous backup and
recovery solution designed for mid-size organizations, workgroups, and remote
Exploitation of a buffer overflow vulnerability in Veritas Netbackup
could lead to a remote Denial Of Service or remote code execution. The
Veritas Netbackup Volume Manager keeps track of the location of volumes
(tapes) needed for backup or restore.
By sending a specially crafted packet to the Volume Manager stack overflow occurs.
This is caused by improper bounds checking.
Exploitation does not require authentication, thereby allowing any remote
attacker to take over the entire system or to disrupt the backup capabilities.
The following versions are confirmed vulnerable:
- Veritas Netbackup 5.0 with MP1 (vmd.exe 220.127.116.110)
- Veritas Netbackup 5.0 with MP2 (vmd.exe 18.104.22.1682)
- Veritas Netbackup 5.0 with MP3 (vmd.exe 22.214.171.1247)
- Veritas Netbackup 5.0 with MP4 (vmd.exe 126.96.36.1992)
- Veritas Netbackup 5.0 with MP5 (vmd.exe 188.8.131.527)
- Veritas Netbackup 5.1 without MP (vmd.exe 184.108.40.206)
- Veritas Netbackup 5.1 with MP1 (vmd.exe 220.127.116.11)
- Veritas Netbackup 5.1 with MP2 (vmd.exe 18.104.22.168)
- Veritas Netbackup 5.1 with MP3A (vmd.exe 22.214.171.124)
Use a firewall to restrict incoming connections to trusted workstations
running the Backup Exec client software, which uses port 13701 TCP.
Latter details released by Symantec state that the vulnerable code may
be able to be exploited through other NetBackup ports/services.
