According to its self-reported version number, the version of JFrog Artifactory installed on the remote host is prior to 6.23.0. It is, therefore, affected by multiple vulnerabilities:

  - The Alias feature in SnakeYAML 1.18 allows entity expansion during a load operation. (CVE-2017-18640)

  - The file name encoding algorithm used internally in Apache Commons Compress 1.15 to 1.18 can get into an infinite     loop when faced with specially crafted inputs. This can lead to a denial of service attack if an attacker can choose     the file names inside of an archive created by Compress. (CVE-2019-12402)

  - The OpenID client application in Atlassian Crowd before version 3.6.2, and from version 3.7.0 before 3.7.1     allows remote attackers to perform a Denial of Service attack via an XML Entity Expansion vulnerability. (CVE-2019-20104)

  - Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers, as demonstrated by the     httputil.ReverseProxy Handler, because it reads a request body and writes a response at the same time. (CVE-2020-15586)

  - PKCE support is not implemented in accordance with the RFC for OAuth 2.0 for Native Apps. Without the use of PKCE,     an attacker is able to obtain the authorization code using a malicious app on the client-side and use it to gain     authorization to the protected resource. (CVE-2020-7692)
