Descriptions
The ConnectionExists function in lib/url.c in libcurl before 7.47.0 does not properly re-use NTLM-authenticated proxy connections, which might allow remote attackers to authenticate as other users via a request, a similar issue to CVE-2014-0015.
La función ConnectionExists en lib/url.c en libcurl en versiones anteriores a 7.47.0 no reutiliza correctamente las conexiones proxy autenticadas por NTML, lo que podría permitir a atacantes remotos autenticarse como otros usuarios a través de una petición, un problema similar a CVE-2014-0015.
Isaac Boukris discovered that cURL, an URL transfer library, reused NTLM-authenticated proxy connections without properly making sure that the connection was authenticated with the same credentials as set for the new transfer. This could lead to HTTP requests being sent over the connection authenticated as a different user.
