CVE Name N/A.
Description CVE-2014-8150 reported an HTTP request injection
vulnerability in libcURL. Asterisk uses libcURL in its
func_curl.so module (the CURL() dialplan function), as well
as its res_config_curl.so (cURL realtime backend) modules.
Since Asterisk may be configured to allow for user-supplied
URLs to be passed to libcURL, it is possible that an
attacker could use Asterisk as an attack vector to inject
unauthorized HTTP requests if the version of libcURL
installed on the Asterisk server is affected by
CVE-2014-8150.
Resolution Asterisk has been patched with a similar patch as libcURL
was for CVE-2014-8150. This means that carriage return and
linefeed characters are forbidden from being in HTTP URLs
that will be passed to libcURL.
