TITLE:
MiniWeb HTTP Server Buffer Overflow and Directory Traversal

SECUNIA ADVISORY ID:
SA28512

VERIFY ADVISORY:
http://secunia.com/advisories/28512/

CRITICAL:
Highly critical

IMPACT:
Exposure of system information, Exposure of sensitive information,
DoS, System access

WHERE:
>From remote

SOFTWARE:
MiniWeb HTTP Server 0.x
http://secunia.com/product/14459/

DESCRIPTION:
Hamid Ebadi has discovered two vulnerabilities in MiniWeb HTTP
Server, which can be exploited by malicious people to disclose
sensitive information, to cause a DoS (Denial of Service), or to
potentially compromise a vulnerable system.

1) A boundary error exists within the "_mwProcessReadSocket()"
function in http.c. This can be exploited to cause a heap-based
buffer overflow via a URL that is 3600-4000 characters long.

Successful exploitation of this vulnerability allows performing a DoS
(Denial of Service) or the potential execution of arbitrary code.

2) Input passed in the URL to the "mwGetLocalFileName()" function in
http.c is not properly sanitised before being used. This can be
exploited to display arbitrary files with directory traversal attacks
of the form ".%2e/.%2e/" or "%2e%2e/%2e%2e/".

The vulnerabilities are confirmed in version 0.8.19. Other versions
may also be affected.

SOLUTION:
Restrict access to the web service.

Use another product.
