Name of the Vulnerable Software and Affected Versions lighttpd versions 1.4.46 through 1.4.63

Description The mod extforward Forwarded function of the mod extforward plugin in lighttpd has a stack-based buffer overflow, which can be exploited for remote denial of service (daemon crash) in a non-default configuration. This configuration requires handling of the Forwarded header in a somewhat unusual manner. Additionally, 32-bit systems are more likely to be affected than 64-bit systems.

Recommendations For lighttpd versions 1.4.46 through 1.4.63, consider disabling the mod extforward Forwarded function of the mod extforward plugin as a temporary workaround to minimize the risk of exploitation. Restrict access to the mod extforward plugin to reduce the likelihood of a daemon crash. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
