Well yes it is a possibly, but so is anything with remote connections involved, says Valve’s John McCaskey. There’s ”no evidence” at this time.
”This is total fear mongering and is unrelated to having dedicated servers or not. Anytime you have a network enabled application accepting data from a remote host (dedicated server or not) you have a risk that the application code has bugs in it allowing buffer overruns that hackers may exploit,” offered McCaskey on the Steam forums.
”These are the same type of vulnerabilities often found and patched in your operating system.” This started from talk of hosting for hacker clients of Modern Warfare 2, or being hosted by a hacker client. It’s all about those packets of data you see.
”However, there is no evidence of any bugs or vulnerabilities of this kind with MW2 or IWNet at this time. If any exploits do come up I’m sure you can expect quick patching from Infinity Ward. We don’t need to continue fear mongering around the possibility of software bugs here.” Clever fellows have already hacked in dedicated server support.
