Format string vulnerability in the logging function in the IM Server (aka IMserve or IMserver) in Ipswitch Instant Messaging (IM) 2.0.8.1 and earlier allows remote authenticated users to cause a denial of service (daemon crash) and possibly have unspecified other impact via format string specifiers in an IP address field.

Weakness

The software 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
Imserver Ipswitch * 2.0.8.1
Instant_messaging Ipswitch * 2.0.8.1

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.
