Description:
Jack Louis has discovered a vulnerability in Webmin, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a vulnerable system.
The vulnerability is caused due to a format string error in the "miniserv.pl" script when logging failed authentication attempts. This can be exploited to consume a large amount of CPU and memory resources on a vulnerable system by attempting to login with a specially crafted username.
It has also been reported that the vulnerability can be exploited in conjunction with a vulnerability in Perl for arbitrary code execution. However, this has not been shown.
For more information:
SA17802
The vulnerability has been confirmed in version 1.240. Other versions may also be affected.
