cURL/libcURL 7.x < 7.33.0 Host Name Validation Bypass
Medium Nessus Network Monitor Plugin ID 9979
SynopsisThe host is running a version of cURL/libcurl that is vulnerable to a host name validation bypass attack vector.
DescriptionVersions of cURL/libcURL older than 7.33.0 are unpatched for a flaw that is due to a file retrieval tool that would disable the 'CURLOPT_SSLVERIFYHOST' check when the 'CURLOPT_SSL_VERIFYPEER' setting was disabled. This may allow a remote attacker to disable SSL certificate host name checks.
SolutionUpgrade cURL to version 7.33.0 or higher.
