The remote SUSE Linux SLES11 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2021:14707-1 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- curl 7.1.1 to and including 7.75.0 is vulnerable to an Exposure of Private Personal Information to an
Unauthorized Actor by leaking credentials in the HTTP Referer: header. libcurl does not strip off user
credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing
HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second
HTTP request. (CVE-2021-22876)
