Multiple format string vulnerabilities in websrv.cpp in Dawn of Time 1.69s beta4 and earlier allow remote attackers to execute arbitrary code via format string specifiers in the (1) username or (2) password fields when accessing certain restricted zones, which are not properly handled by the (a) processWebHeader and (b) filterWebRequest functions.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

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.
