Description Preview
The vulnerability in cURL and libcurl versions prior to 7.36.0 occurs when using the OpenSSL, axtls, qsossl, or gskit libraries for TLS. These libraries recognize a wildcard IP address in the subject's Common Name (CN) field of an X.509 certificate, potentially enabling attackers to impersonate arbitrary SSL servers by creating a malicious certificate issued by a legitimate Certification Authority.
Overview
This vulnerability affects cURL and libcurl versions before 7.36.0 when utilizing certain TLS libraries, allowing for potential man-in-the-middle attacks through spoofed SSL servers.
Remediation
To remediate this vulnerability, users are advised to update their cURL and libcurl installations to version 7.36.0 or later. It is crucial to ensure that the TLS libraries being used are not susceptible to recognizing wildcard IP addresses in the CN field of X.509 certificates.
