Synopsis

lighttpd < 1.4.30 base64_decode Function Out-of-Bounds Read Error DoS

Description

According to its banner, the version of lighttpd running on the remote host is prior to 1.4.30. It is, therefore, affected by a denial of service vulnerability. The HTTP server allows out-of-bounds values to be decoded during the auth process and later uses these values as offsets. Using negative values as offsets can result in application crashes.

Note that the scanner has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to lighttpd version 1.4.30 or later.
