The version of curl installed on the remote host is prior to 7.61.1-12.100. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1549 advisory.

    A flaw was found in curl. This flaw lies in the --ssl-reqd option or related settings in libcurl. Users     specify this flag to upgrade to TLS when communicating with either IMAP, POP3 or a FTP server. An attacker     controlling such servers could return a crafted response which could lead to curl client continue its     operation without TLS encryption leading to data being transmitted in clear text over the network. The     highest threat from this vulnerability is to data confidentiality. (CVE-2021-22946)

    A flaw was found in curl. The flaw lies in how curl handles cached or pipelined responses that it receives     from either a IMAP, POP3, SMTP or FTP server before the TLS upgrade using STARTTLS. In such a scenario     curl even after upgrading to TLS would trust these cached responses treating them as valid and     authenticated and use them. An attacker could potentially use this flaw to carry out a Man-In-The-Middle     attack. The highest threat from this vulnerability is to data confidentiality. (CVE-2021-22947)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
