TITLE:
MaxDB Web Tools Buffer Overflow and Denial of Service Vulnerabilities
SECUNIA ADVISORY ID:
SA13397
VERIFY ADVISORY:
http://secunia.com/advisories/13397/
CRITICAL:
Moderately critical
IMPACT:
DoS, System access
WHERE:
From local network
SOFTWARE:
MaxDB 7.x
http://secunia.com/product/4012/
DESCRIPTION:
Evgeny Demidov has reported two vulnerabilities in MaxDB, which can
be exploited by malicious people to cause a DoS (Denial of Service)
or compromise a vulnerable system.
1) A boundary error within the WebDAV handler can be exploited to
cause a stack-based buffer overflow by passing an overly long
"Overwrite" header.
Successful exploitation allows execution of arbitrary code.
2) A NULL pointer dereference error in WAHTTP can be exploited to
crash the service by sending a specially crafted HTTP request without
a "Host:" header.
The vulnerabilities have been reported in version 7.5.00.18 and
prior.
SOLUTION:
The vulnerabilities have reportedly been fixed in version 7.5.00.19:
