Format string vulnerability in the cryactio function in Crysis 1.1.1.5879 allows remote authenticated users to execute arbitrary code via format string specifiers in the user name, which is triggered when the game character is killed.

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
Crysis Crytek 1.1.1.5879 1.1.1.5879

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.
