Summary 0001426: Make ConsoleCommand whitelist-based
Revision 2013-07-23 12:09 by Dusk
Description In light of all these exploits and abuse going about, I thought I'd put this on the table: Make ConsoleCommand whitelist-based. Instead of blacklisting the bad commands, white-list the ones we want ConsoleCommand to use until we're ready to cut it off. It'd be at least a partial fix to this security issue.

Further it'd also give us a list of stuff we need to allow ACS to do before we can finally say bye bye to ConsoleCommand - while we patch the use cases, we could prevent new ones from arising. I'm not too sure exactly what ones need to be set. Also I'd suggest changing the new cvar flag to CVAR_ALLOWSETBYACS or something like that to do the same whitelisting to cvars.

Description In light of recent events of exploits and abuse, I'm becoming more and more convinced this would be a good idea.

Make ConsoleCommand whitelist-based. Instead of blacklisting the bad commands, white-list the ones we want ConsoleCommand to use... for now. It'd be at least a partial fix to this number one security issue.

Further it'd also give us a list of stuff we need to allow ACS to do before we can finally say bye bye to ConsoleCommand - while we patch the use cases, we could prevent new ones from arising.
