NetVault configure.cfg file buffer overflow
| netvault-configurecfg-bo (19932) |  High Risk |
Description:
NetVault is vulnerable to a stack-based buffer overflow caused by improper bounds checking of user-supplied input in the processing of the configure.cfg file. By creating a specially-crafted computername 'Name=' entry containing more than 111 bytes, a local attacker with access to the configure.cfg file, could overflow a buffer and execute arbitrary code on the system with SYSTEM level privileges, once the NetVault Process Manager restarts.
Note: A remote attacker could also exploit this vulnerability by connecting to port 20031 and sending a specially-crafted clientname entry in the Available NetVault Machines list to overflow a buffer and execute arbitrary code on the system.
Platforms Affected:
- BakBone, NetVault 7.3 and prior
- Microsoft, Windows 2003 Server
