Test ID:1.3.6.1.4.1.25623.1.0.147394
Category:Denial of Service
Title:Lighttpd 1.4.46 - 1.4.63 DoS Vulnerability
Summary:Lighttpd is prone to a denial of service (DoS) vulnerability.
Description:Summary:
Lighttpd is prone to a denial of service (DoS) vulnerability.

Vulnerability Insight:
The mod_extforward_Forwarded function of the mod_extforward
plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote
denial of service (daemon crash) in a non-default configuration. The non-default configuration
requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is
much more likely to be affected than a 64-bit system.

Affected Software/OS:
Lighttpd version 1.4.46 through 1.4.63.

Solution:
Update to version 1.4.64 or later.

CVSS Score:
4.3

CVSS Vector:
AV:N/AC:M/Au:N/C:N/I:N/A:P
