Multiple format string vulnerabilities in the configuration file in SonicWALL GLobal VPN Client 3.1.556 and 4.0.0.810 allow user-assisted remote attackers to execute arbitrary code via format string specifiers in the (1) Hostname tag or the (2) name attribute in the Connection tag. NOTE: there might not be any realistic circumstances in which this issue crosses privilege boundaries.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Affected Software

Name Vendor Start Version End Version
Global_vpn_client Sonicwall 3.1.556 3.1.556
Global_vpn_client Sonicwall 4.0.0.810 4.0.0.810

Extended Description

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
