Description Vasyl Kaigorodov 2015-01-29 11:46:26 UTC
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.

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.
