GroupWise < 7.0.0 SP2 WebAccess GWINTER.exe Base64 Decoding Overflow
Medium Nessus Network Monitor Plugin ID 3971
SynopsisThe remote host is vulnerable to a buffer overflow.
DescriptionThe remote host is running a version of GroupWise WebAccess from Novell that fails to sanitize HTTP authentication requests. An overly long request will generate an overflow on the remote WebAccess server. An attacker exploiting this flaw would only need to be able to connect to the service and send an HTTP basic authentication request. Successful exploitation would result in the attacker executing arbitrary code.
SolutionUpgrade to version 7.0.0 SP2 or higher.
