The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 8838abf0-bc47-11ec-b516-0897988a1c07 advisory.

  • An SSRF issue was discovered in Asterisk through 19.x. When using STIR/SHAKEN, it’s possible to send arbitrary requests (such as GET) to interfaces such as localhost by using the Identity header. This is fixed in 16.25.2, 18.11.2, and 19.3.2. (CVE-2022-26499)

  • An issue was discovered in Asterisk through 19.x. When using STIR/SHAKEN, it is possible to download files that are not certificates. These files could be much larger than what one would expect to download, leading to Resource Exhaustion. This is fixed in 16.25.2, 18.11.2, and 19.3.2. (CVE-2022-26498)

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