Heya lists & 3APA3A, 3APA3A a écrit :
Dear full-disclosure@lists.grok.org.uk, There is interesting thing with event logging on Windows. The only security aspect of it is event log record tampering and performance degradation, but it may become sensitive is some 3rd party software is used for automated event log analysis. The problem is a kind of "Format string" vulnerability where user-supplied input is used for event log record. For ReportEvent() function %1, %2, etc have a special meaning and are replaced with corresponding string from lpStrings.
It looks more like a variable replacement (like $0 $1 ... in bash shell) than a format string issue to me. And it seems indeed to be a relevant information disclosure bug. Cheers, endrazine- _______________________________________________ Full-Disclosure - We believe in it.
